Molecular Modeling of some 1,3,4-Oxadiazole Derivatives as EGFR Inhibitors for the Treatment of Cancer

Background: Cancer is a group of illnesses characterised by the impartial increase and unfolding of somatic cells. A variety of natural compounds, such as curcumin, zingiberine and their composites, and synthetic organic derivatives of imidazole, benzothiazole, oxadiazole, quinazoline etc., have been developed as anticancer agents. But many of these show various side effects, drug resilience, and toxicity to the normal cells of the host body. Therefore, there is still demand to develop new synthetic derivatives to improve their pharmacological profile. Objective: The Aim of this study is to understand the binding mode and to check the drug likeliness of numerous 1,3,4-oxadiazole derivatives as EGFR inhibitors for the treatment of cancer. The objective of the study is to screen newly designed derivatives of 1,3,4-oxadiazole using molecular docking and ADMET studies as EGFR inhibitors. Methods: In silico docking studies were performed using AutoDockVina software, and compounds were further studied for ADME and toxicity using SwissADME and pkCSM software, respectively. Results: Considering the docking results, pharmacokinetic behaviour and toxicity profile, eight derivatives (derivatives 2,3,4,5,10,13,16, and 17) showed potential as EGFR inhibitors. Conclusion: Compounds 2 and 3 showed the highest binding affinity in the pocket of EGFR and also displayed a better pharmacokinetic profile. Therefore, these derivatives can be used in the management of cancer and can be taken further for wet-lab studies.

Nanoparticle-mediated metronomic chemotherapy in cancer: A paradigm of precision and persistence

Current methods of cancer therapy have demonstrated enormous potential in tumor inhibition. However, a high dosage regimen of chemotherapy results in various complications which affect the normal body cells. Tumor cells also develop resistance against the prescribed drugs in the whole treatment regimen increasing the risk of cancer relapse. Metronomic chemotherapy is a modern treatment method that involves administering drugs at low doses continuously, allowing the drug sufficient time to take its effect. This method ensures that the toxicity of the drugs is to a minimum in comparison to conventional chemotherapy. Nanoparticles have shown efficacy in delivering drugs to the tumor cells in various cancer therapies. Combining nanoparticles with metronomic chemotherapy can yield better treatment results. This combination stimulates the immune system, improving cancer cells recognition by immune cells. Evidence from clinical and pre-clinical trials supports the use of metronomic delivery for drug-loaded nanoparticles. This review focuses on the functionalization of nanoparticles for improved drug delivery and inhibition of tumor growth. It emphasizes the mechanisms of metronomic chemotherapy and its conjunction with nanotechnology. Additionally, it explores tumor progression and the current methods of chemotherapy. The challenges associated with nano-based metronomic chemotherapy are outlined, paving the way for prospects in this dynamic field.

Abstract LT08: Extracellular Vesicle Surface Display Enhances the Therapeutic Efficacy and Safety Profile of Cancer Immunotherapy

Abstract As our understanding of the complex interactions between the immune system and cancer has progressed, so has the identification of novel targets and ligands that can modulate effective anti-cancer immune responses. While immunotherapy has emerged as a mainstay in cancer therapy, its efficacy has been limited by the potential for off-target toxicity against normal body cells. In this study, we present a nanoparticle-based delivery system that enhances the signaling efficacy of immunomodulatory ligands while concurrently limiting systemic toxicity. We demonstrate that extracellular vesicles (EVs), lipid bilayer enclosed nanoparticles released by cells, can be efficiently engineered to display multiple immunomodulatory ligands on their surface. Display of immunomodulatory ligands such as agonistic CD137 and CD40 antibodies on the EV surface significantly enhanced their therapeutic efficacy over equivalent doses of free ligands by inducing ligand multimerization, efficient receptor crosslinking and the formation of immune synapses. EVs conjugated with a complementary combination of immune stimulatory ligands and immune checkpoint inhibitors were able to shift the tumor immune milieu towards an anti-tumorigenic phenotype in a lung metastatic melanoma allograft and suppress tumor progression to a greater extent than an equivalent dose of free ligands. We also demonstrate the ability of EVs to co-deliver intraluminally loaded TLR agonists which synergize with surface displayed agonistic CD40 antibodies to induce effective anti-tumor responses and tumor regression in a metastatic autochthonous cell-derived model of PDAC. Remarkably, we also observed that EV-associated immunotherapeutics were limited in their biodistribution to the tumor microenvironment, resulting in significantly lower off-target toxicity than treatment with free ligands. In summary, we present an EV-based delivery approach that allows the use of potent cancer immunotherapy combinations to achieve superior anti-tumor responses at significantly lower doses with less side-effects than is possible with conventional administration methods for cancer immunotherapy.

Plant mediated biosynthesis of Mn3O4 nanostructures and their biomedical applications

Nanomaterials have drawn significant attention for their biomedical and pharmaceutical applications. In the present study, manganese tetra oxide (Mn3O4) nanoparticles were prepared greenly, and their physicochemical properties were studied. Taxus baccata acetone extract was used as a safely novel precursor for reducing and stabilizing nanoparticles. The synthesized nanoparticles were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), Brunauer–Emmett–Teller (BET), and Barrett-Joyner-Halenda (BJH) and X-ray diffraction (XRD). The cytotoxicity of Mn3O4 (hausmannite) nanostructures was evaluated against murine macrophage cell line J774-A1 and U87 glioblastoma cancer cells for approximately 72 h. Spherical Mn3O4 nanoparticles with tetragonal spinel structures demonstrated minimal toxicity against normal body cells with CC50 around 876.38 μg mL−1. Moreover, Mn3O4 nanoparticles as well as the combination of antimoniate meglumine and Mn3O4 nanoparticles exhibited maximum mortality in Leishmania major. The synthesized nanominerals displayed a significant inhibitory effect against glioblastoma cancer cells at 100 μg mL−1. The selective cytotoxicity of Mn3O4 nanoparticles indicates that these biogenic agents can be employed simultaneously for diagnostic and therapeutic applications in medical applications.

An overview on 2-indolinone derivatives as anticancer agents

2-Indolinone nucleus is considered one of a promising heterocyclic core in medicinal chemistry that showed numerous range of activity among which antimicrobial, antioxidant, antiviral, antitubercular and anticancer activities. Cancer targeting is still an issue so there is a need for developing new agents that inhibit cancer growth without or low effect on normal body cells. Some derivatives of indolin-2-one are known to be a critical structure in some inhibitors of receptor tyrosine kinases (RTKs); a cancer target therapy, for example, Sunitinib. Herein in this review we focus on 2-indolinone derivatives as RTKs inhibitors as cancer targeting therapy.

Anticancer activity of cloned Nisin as an alternative therapy for MCF-7 brest cancer cell line.

Despite advancements in treatment and detection, cancer remains one of the most common causes of death worldwide. Conventional chemotherapeutic drugs used to treat cancer have non-specific toxicity toward normal body cells, which leads to several adverse effects. Second, malignancies are known to develop resistance to chemotherapy over time. As a result, the demand for novel anticancer drugs is growing daily. The most frequent type of cancer among women is breast cancer. Utilizing cloned Nisin as an anticancer was the purpose of this study using Gibson cloning and a cell-free peptide synthesis system, then purification of the target protein. The antiproliferative effect of Nisin against a breast cancer MCF-7 cell line was also determined using an MTTassay, and viability in cell lines was measured using acridine orangeand propidium iodide. Our findings demonstrate the successful isolation and cloning of the NisA, gene in addition to inducing of peptide synthesis system and then purification of a target protein. MTTassay results indicate that Nisin exhibits a high and selective cytotoxicity against the MCF-7 cell line with an IC50 value of 11.68 μg/ml. This data suggest that the NisA gene had in vitro antiproliferative effect against breast cancer cell. However, more research, including a combination of the NisA gene with other anticancer therapy in clinical use. In addition, in vivo studies are required.

Oncolytic potential of autonomous parvoviruses

Background. In many countries, more than 40 oncolytic viruses from 10 different families are undergoing clinical trials (phase I, II, III) against various types of cancer; some of them have already been approved for use. The results of the experimental studies that deal with the development of oncolytic drugs based on autonomous parvoviruses deserve special attention.
 Purpose. The purpose of the study was to analyze and summarize literature sources that are concerned with the development of oncolytic drugs based on autonomous parvoviruses.
 Materials and Methods. Publications were selected using keywords in PubMed (https://pubmed.ncbi.nlm.nih.gov/) and Google Scholar (https://scholar.google.com/) databases published over the period from 2010 to 2023.
 Results. Among autonomous parvoviruses, protoparvoviruses are the most promising for the development of anticancer drugs. They detect CPE mainly in tumor cells, CPE is absent or limited in non-transformed human and rodent cell lines. Many of them are capable of actively replicating in cancer cells without destroying normal body cells. They primarily block the pathways of activation of type I interferons. The main non-structural viral protein NS1 plays a significant role in the manifestations of oncolytic activity of protoparvoviruses.
 Conclusions. Numerous studies continue to be directed at studying the mechanisms associated with the oncolytic properties of autonomous parvoviruses. The use of recombinant parvoviruses allows their oncolytic potential to be enhanced.

Paraneoplastic Syndromes from Head to Toe: Pathophysiology, Imaging Features, and Workup

Patients often have symptoms due to the mass effect of a neoplasm on surrounding tissues or the development of distant metastases. However, some patients may present with clinical symptoms that are not attributable to direct tumor invasion. In particular, certain tumors may release substances such as hormones or cytokines or trigger an immune cross-reactivity between malignant and normal body cells, resulting in characteristic clinical features that are broadly referred to as paraneoplastic syndromes (PNSs). Recent advances in medicine have improved the understanding of the pathogenesis of PNSs and enhanced their diagnosis and treatment. It is estimated that 8% of patients with cancer develop a PNS. Diverse organ systems may be involved, most notably the neurologic, musculoskeletal, endocrinologic, dermatologic, gastrointestinal, and cardiovascular systems. Knowledge of various PNSs is necessary, as these syndromes may precede tumor development, complicate the patient's clinical presentation, indicate tumor prognosis, or be mistaken for metastatic spread. Radiologists should be familiar with the clinical presentations of common PNSs and the selection of appropriate imaging examinations. Many of these PNSs have imaging features that can assist with arriving at the correct diagnosis. Therefore, the key radiographic findings associated with these PNSs and the diagnostic pitfalls that can be encountered during imaging are important, as their detection can facilitate early identification of the underlying tumor, reveal early recurrence, and enable monitoring of the patient's response to therapy. © RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Body image and the level of stress in cervical cancer patients

Introduction: Chemotherapy is one of the management applied to cervical cancer patients. Chemotherapy is beneficial to kill cancer cells, but it affects normal body cells, such as hair roots, skin, and changes in physical appearance. These physical changes result in poor self-assessment and stress. This study was conducted to describe the correlation between body image and stress level of cervical cancer patients undergoing chemotherapy at the Gynecology Polyclinic, Dr. Kariadi General Hospital Medical Center Semarang. Methods: This type of research is quantitative using a correlational research design. The research process was carried out in 2020 at Dr. Kariadi General Hospital Medical Center Semarang with the number of samples obtained was 87 respondents. Results: It showed that there was a relationship between body image and stress levels in cervical cancer patients receiving chemotherapy (r = -0.313 and p-value = 0.003). With a change in physical appearance, patients would feel something different which affects psychological situations and further causes stress. Conclusions: The level of stress has a significant correlation with the body image score of cervical cancer.

Hyaluronic Acid-Based Nanomaterials Applied to Cancer: Where Are We Now?

Cancer cells normally develop the ability to rewire or reprogram themselves to become resistant to treatments that were previously effective. Despite progress in understanding drug resistance, knowledge gaps remain regarding the underlying biological causes of drug resistance and the design of cancer treatments to overcome it. So, resistance acquisition remains a major problem in cancer treatment. Targeted therapeutics are considered the next generation of cancer therapy because they overcome many limitations of traditional treatments. Numerous tumor cells overexpress several receptors that have a high binding affinity for hyaluronic acid (HA), while they are poorly expressed in normal body cells. HA and its derivatives have the advantage of being biocompatible and biodegradable and may be conjugated with a variety of drugs and drug carriers for developing various formulations as anticancer therapies such as micelles, nanogels, and inorganic nanoparticles. Due to their stability in blood circulation and predictable delivery patterns, enhanced tumor-selective drug accumulation, and decreased toxicity to normal tissues, tumor-targeting nanomaterial-based drug delivery systems have been shown to represent an efficacious approach for the treatment of cancer. In this review, we aim to provide an overview of some in vitro and in vivo studies related to the potential of HA as a ligand to develop targeted nanovehicles for future biomedical applications in cancer treatment.

The effects of amitriptyline on human embryonic kidney cells growth and proliferation in vitro

Many studies have shown that antidepressants, including amitriptyline, can cause side effects on normal human cells, although the exact effects of amitriptyline on normal human cells are unclear. Accordingly, the present study investigated the cytotoxic effects of amitriptyline on the human embryonic kidney cell line. In this experimental-laboratory study, cells were divided into control group (no drug-treated) and amitriptyline treatment groups (treated with 39.06, 12.78, 156.25, 312.5, 625, 1250 and 2500 μg/ml of amitriptyline). MTT method was used to assay the cytotoxic effects of amitriptyline at 24 and 48 hours. The data were analyzed by one-way analysis of variance. Treatment with 39.06 and 78.12 μg/ml of amitriptyline for 24 hours had no significant effect on the viability of Hek-293 cells, but treatment with 156.25 μg/ml and higher concentrations of amitriptyline significantly reduced the viability of Hek-293 cells. Treatment of cells for 48 hours showed a significant reduction in cell viability at all concentrations. Amitriptyline has cytotoxic effects on normal human embryonic kidney cells and these effects depend on the dose and duration of treatment. The findings of this study can be of significant importance in terms of the side effects of amitriptyline consumption on normal cells of the human body.

Photonic crystal race track ring resonator design for the detection of cancer cells

Some of body’s cells grow in an uncontrolled manner and spreads to the other parts of the body due to cancer. Also in cancer, normal body cells infiltrate and destroy rapidly. Though the advanced treatment process has improved the survival rates of cancer, but still the cancer holds the second highest place as the leading cause of death throughout the world. But diagnosis at the earlier stage may cure the disease and improve the survival rates. In the reported article, photonic crystal based racetrack shaped ring resonator is designed using FDTD simulation to conduct study of cancer cell detection and a very high sensitivity of 900 nm/RIU is obtained from the analysis.

Investigation of Eutectic Mixtures of Fatty Acids as a Novel Construct for Temperature-Responsive Drug Delivery.

BackgroundMost of the traditional nanocarriers of cancer therapeutic moieties present dose-related toxicities due to the uptake of chemotherapeutic agents in normal body cells. The severe life-threatening effects of systemic chemotherapy are well documented. Doxorubicin, DOX is the most effective antineoplastic agent but with the least specific action that is responsible for severe cardiotoxicity and myelosuppression that necessitates careful monitoring while administering. Stimuli-sensitive/intelligent drug delivery systems, specifically those utilizing temperature as an external stimulus to activate the release of encapsulated drugs, have become a subject of recent research. Thus, it would be ideal to have a nanocarrier comprising safe excipients and controllable drug release capacity to deliver the drug at a particular site to minimize unwanted and toxic effects of chemotherapeutics. We have developed a simple temperature-responsive nanocarrier based on eutectic mixture of fatty acids. This study aimed to develop, physicochemically characterize and investigate the biological safety of eutectic mixture of fatty acids as a novel construct for temperature-responsive drug release potential.MethodsWe have developed phase change material, PCM, based on a series of eutectic mixtures of fatty acids due to their unique and attractive physicochemical characteristics such as safety, stability, cost-effectiveness, and ease of availability. The reversible solid-liquid phase transition of PCM is responsible to hold firm or actively release the encapsulated drug. The eutectic mixtures of fatty acids (stearic acid and myristic acid) along with liquid lipid (oleic acid) were prepared to exhibit a tunable thermoresponsive platform. Doxorubicin-loaded lipid nanocarriers were successfully developed with combined hot melt encapsulation (HME) and sonication method and characterized to achieve enhanced permeability and retention (EPR) effect-based solid tumor targeting in response to exogenous temperature stimulus. The cytotoxicity against melanoma cell lines and in vivo safety studies in albino rats was also carried out.ResultsDoxorubicin-loaded lipid nanocarriers have a narrow size distribution (94.59–219.3 nm), and a PDI (0.160–0.479) as demonstrated by photon correlation microscopy and excellent colloidal stability (Z.P value: −22.7 to −32.0) was developed. Transmission electron microscopy revealed their spherical morphology and characteristics of a monodispersed system. A biphasic drug release pattern with a triggered drug release at 41°C and 43°C and a sustained drug release was observed at 37°C. The thermoresponsive cytotoxic potential was demonstrated in B16F10 cancer cell lines. Hemolysis assay and acute toxicity studies with drug-free and doxorubicin lipid nanocarrier formulations provided evidence for their non-toxic nature.ConclusionWe have successfully developed a temperature-responsive tunable platform with excellent biocompatibility and intelligent drug release potential. The formulation components being from natural sources present superior characteristics in terms of cost, compatibility with normal body cells, and adaptability to preparation methods. The reported preparation method is adapted to avoid complex chemical processes and the use of organic solvents. The lipid nanocarriers with tunable thermoresponsive characteristics are promising biocompatible drug delivery systems for improved localized delivery of chemotherapeutic agents.

Pan-cancer analysis of microRNA expression profiles highlights microRNAs enriched in normal body cells as effective suppressors of multiple tumor types: A study based on TCGA database

BackgroundMicroRNAs (miRNAs) are frequently deregulated in various types of cancer. While antisense oligonucleotides are used to block oncomiRs, delivery of tumour-suppressive miRNAs holds great potential as a potent anti-cancer strategy. Here, we aim to determine, and functionally analyse, miRNAs that are lowly expressed in various types of tumour but abundantly expressed in multiple normal tissues.MethodsThe miRNA sequencing data of 14 cancer types were downloaded from the TCGA dataset. Significant differences in miRNA expression between tumor and normal samples were calculated using limma package (R programming). An adjusted p value < 0.05 was used to compare normal versus tumor miRNA expression profiles. The predicted gene targets were obtained using TargetScan, miRanda, and miRDB and then subjected to gene ontology analysis using Enrichr. Only GO terms with an adjusted p < 0.05 were considered statistically significant. All data from wet-lab experiments (cell viability assays and flow cytometry) were expressed as means ± SEM, and their differences were analyzed using GraphPad Prism software (Student’s t test, p < 0.05).ResultsBy compiling all publicly available miRNA profiling data from The Cancer Genome Atlas (TCGA) Pan-Cancer Project, we reveal a small set of tumour-suppressing miRNAs (which we designate as ’normomiRs’) that are highly expressed in 14 types of normal tissues but poorly expressed in corresponding tumour tissues. Interestingly, muscle-enriched miRNAs (e.g. miR-133a/b and miR-206) and miRNAs from DLK1-DIO3 locus (e.g. miR-381 and miR-411) constitute a large fraction of the normomiRs. Moreover, we define that the CCCGU motif is absent in the oncomiRs’ seed sequences but present in a fraction of tumour-suppressive miRNAs. Finally, the gain of function of candidate normomiRs across several cancer cell types indicates that miR-206 and miR-381 exert the most potent inhibition on multiple cancer types in vitro.ConclusionOur results reveal a pan-cancer set of tumour-suppressing miRNAs and highlight the potential of miRNA-replacement therapies for targeting multiple types of tumour.

Ex Vivo Expansion and Activation of Natural Killer Cells from Thalassemia Patients for Adoptive Immunotherapy of Tumors

Therapeutic outcomes for high grade soft tissue and bone sarcomas still remains poor, which is largely due to severe chemoresistance of this aggressive tumor type. Therefore, alternative approaches are needed addressing novel targets that are different from current multimodal chemotherapy. Natural killer cells are a major component of the innate immune system due to their ability to exert direct cytotoxicity against malignant cells or otherwise stressed cells. Interest in natural killer cell-based immunotherapy has increased since new protocols for the purification and expansion of large numbers of highly cytotoxic cells have become available. Peripheral blood mononuclear cells from patients with different thalassemia subtypes were co-cultured with irradiated, genetically engineered K562-mb15-41BBL cells in the presence of interleukin-2 for 14 d. Expansion efficiency, natural killer cell receptor repertoire and the expression of natural killer cell ligands on cell lines were investigated by flow cytometry. Cytolytic activity of natural killer cells was tested using the europium target detection assay based on time-resolved fluorometry. Ex vivo expansion of peripheral blood mononuclear cells from thalassemia patients allowed the generation of large numbers of natural killer cells exhibiting enhanced activation characteristics and high cytolytic activity against tumor-cell lines, yet retaining tolerance towards normal body cells. Moreover, this method has been adapted to clinical-grade conditions, producing a sufficient quantity of highly cytotoxic natural killer cells for immunotherapy. Based on these data, adoptive transfer of ex vivo expanded and activated natural killer cells deserve further clinical evaluation as a possible new treatment option for tumor and other blood diseases patients.

A Comparison Between Organic and Inorganic Nanoparticles: Prime Nanoparticles for Tumor Curation

In the modern era, nanotechnology is one of the rapidly growing fields in many biomedical applications especially in delivering therapeutics for the curation of tumor cells. Cancer is a lethal disease that grows silently in the human body, caused by mutations in the genetic material of cells. The presence of a high number of physiologically active chemicals on the cancer cell surface does not particularly lead to tumor cell targeting. The lack of effective targeting of tumor cells by conventionally administered chemotherapeutic drugs demands the use of nanomedicine. Conventional medicines have immense cytotoxic effects, i.e., they do not kill tumor cells only but also destroy normal body cells. Nanoparticles (NPs) have an advantage over conventional therapeutic methods due to their small size, large surface area, and especially for targeting tumor cells without harming normal body cells. Based on durability and molecular weight, NPs are classified as organic and inorganic nanoparticles. Common organic and inorganic nanoparticles are highly effective against cancer curation and have high efficacy values along with their mechanism of action.

The Devastating Disease Cancer- A Theoretical Study and Recent Trends: Review

Cancer is a lethal disease and the whole world is affected by this. Cancer is the second most dangerous and death-leading disease all over the world. In the normal human body, cells can grow and after some time a cell leads to death and another cell grows, by this procedure, particular cells and all types of cells remain constant but in Cancer disease, abnormal cells develop and divide uncontrollably and destroy the normal body cells and tissues mainly mutation is responsible for cancer. This research paper is trying to help in understanding all the important points about cancer disease. Cancer is the elementary unit of tumors, it leads to uncontrolled division of cells. Chronological growth of mutation in oncogenesis is responsible for the origin of cancer. Unbounded division of cells gives birth to the tumor, which is of two types, benign tumor and another is a malignant tumor which is also known as cancer. There are many types of tumor antigens that are present in the human body and sometimes react against these antigens in the form of destroying tumors, NK cell activity, and many other ways. This lethal sickness is of many types like breast cancer, lung cancer, bladder cancer, kidney, and renal pelvis cancer, thyroid cancer, melanoma of the skin, pancreatic cancer, and liver cancer. In all among Cancer pancreatic cancer is difficult to recognize and diagnose that's why it is rapidly killing cancer. The death rate is higher among men than women. According to IARC in the year 2020, the graph of death by cancer increases, a total of 19.3 million cases appear and 10 million had to lose their lives. As reported by the National Cancer Institute there are some methods that are helping in the healing of carcinoma disease:- Hormone therapy, immunotherapy, radiotherapy, surgery, stem cell transplantation, etc. This research paper outlines the current research and development to prevention and cure of cancer and explains all about cancer, and we try to give some little contribution to get rid of this dangerous disease.

Inhibitory mechanism of BAC-IB17 against β-lactamase mediated resistance in methicillin-resistant Staphylococcus aureus and application as an oncolytic agent

Cancer remains a foremost cause of deaths worldwide, despite several advances in the medical science. The conventional chemotherapeutic methods are not only harmful for normal body cells but also become inactive due to the development of resistance by cancer cells. Therefore, the demand of safe anticancer agents is increasing and enforced the bottomless research on the bacteriocins. Several studies have reported the selective anticancer property of bacteriocins. Current research is the contribution to explore the exact mechanism of action and in vitro application of bacteriocin (BAC-IB17) as an oncolytic agent. In this study, β-lactamase mediated resistance of methicillin resistant Staphylococcus aureus (MRSA) was studied and inhibitory mechanism of MRSA by BAC-IB17 was investigated. Cytotoxic studies were conducted to analyze the anticancerous potential of BAC-IB17. Results revealed that BAC-IB17 inhibited the β-lactamase and produced profound effect on the membrane integrity of MRSA confirmed by scanning electron microscope (SEM). FTIR spectroscopic analysis revealed the changes in the functional groups of bacterial cells before and after treatment with BAC-IB17. BAC-IB17 also found anticancer in nature as it kills HeLa cell lines with the IC50 value of 12.5 μg mL−1 with no cytotoxic effect on normal cells at this concentration. This specific anticancer property of BAC-IB17 will make it a promising candidate for the treatment of cancer after further clinical trials. Moreover, BAC-IB17 may control MDR bacteria responsible for the secondary complications in cancer patients.

Thymoquinone-chemotherapeutic combinations: new regimen to combat cancer and cancer stem cells.

Cancer is a worldwide disease that causes millions of cases of mortality and morbidity. The major problem associated with the cancer is its resistance to conventional therapy and a high relapse rate. The use of chemotherapy to treat cancer began at the start of the twentieth century with attempts to control cancer. In time advance, many cancer chemotherapeutic agents have been developed for cancer treatment with different mechanisms of action including the alkylating agents, antimetabolites, antimicrotubule, topoisomerase inhibitors, and cytotoxic antibiotics, all of which have toxic effects toward normal cells in the body. Here, we reviewed chemotherapeutics' anticancer role potentiation and safety by thymoquinone (TQ) alone or in combination with the most common therapeutic drugs. Our search was done through PubMed, Science Direct, Springer Link, Taylor & Francis Online, Wiley Online Library, Nature publication group, SAGE Journals, and Web of Science databases. We recognized that TQ-chemotherapeutics combination increased chemo-modulation to the anticancer effect of different chemotherapeutics and protected the normal body cells from the toxic injuries that are induced by chemotherapeutics based on its antioxidant power. Moreover, the current study investigates the possible combinatory effect of TQ and chemotherapeutics to control cancer stem cells through molecular docking targeting of wingless/integrated (Wnt) and Hedgehog (Hh). We found that TQ modulates the Wnt and Hh pathways, by binding with tankyrase-2 and smoothened 7TM receptor, respectively, more efficiently than most chemotherapeutics drugs, while methotrexate showed high-binding affinity compared with TQ. Therefore, we encourage researchers to investigate the chemo-modulatory potential and protective effects of TQ in combination with chemotherapeutics for either cancer or cancer stem cell treatment.
