Streptomyces Paradigm in Anticancer Therapy: A State-of-the Art Review

Abstract: Cancer is one of the biggest threats to human health with a global incidence of 23.6 million, mortality of 10 million, and an estimated 250 million lost in disability-adjusted life years (DALYs) each year. Moreover, the incidence, mortality, and DALYs have increased over the past decade by 26.3%, 20.9%, and 16.0%, respectively. Despite significant evolutions in medical therapy and advances in the DNA microarray, proteomics technology, and targeted therapies, anticancer drug resistance continues to be a growing concern and invites regular discovery of potent agents. One such agent is the microbe-producing bioactive compounds like Streptomyces, which are proving increasingly resourceful in anticancer therapy of the future. Streptomyces, especially the species living in extreme conditions, produce bioactive compounds with cytolytic and anti-oxidative activity which can be utilized for producing anticancer and chemo-preventive agents. The efficacy of the derived compounds has been proven on cell lines and some of these have already established clinical results. These compounds can potentially be utilized in the treatment of a variety of cancers including but not limited to colon, lung, breast, GI tract, cervix, and skin cancer. The Streptomyces, thus possess the armory to fuel the anticancer agents of the future and help address the problem of rising resistance to currently available anti-cancer drugs. We conducted a state-of-art review using electronic databases of PubMed, Scopus, and Google scholar with an objective to appraise the currently available literature on Streptomyces as a source of anti-cancer agents and to compile the clinically significant literature to update the clinicians.

A Review on Indole as a Cardinal Scaffold for Anticancer Drugs Development

Abstract: Chemotherapy is the mainstay of therapeutic cancer therapy; however, the development of resistance typically makes it less effective. There are continuous efforts by researchers to find novel lead compounds with potent anti-cancer activity. Generally, synthetic or natural heterocyclic compounds have been investigated in detail as a scaffold for cancer therapeutics. Among them, indole, owing to its unique physiochemical and biological properties, provides a promising platform for the development of pharmacophores for drug development against cancer, acting via various mechanisms. Till now, several indole-based derivatives have been identified as anti-cancer agents, which are either being used in clinics or are in various phases of clinical trials, suggesting their importance in anti-cancer drug development. These anti-cancer drugs have been classified into different classes depending on their mechanism of action. For example, histone deacetylase inhibitors (HDAC inhibitors), silent mating type information regulation 2 homolog (SIRT) inhibitors, tubulin inhibitors, proviral insertion site in Moloney murine leukemia virus (Pim) inhibitors, DNA Topoisomerase inhibitors, and kinase inhibitors. In this review, the author's approach is to compile the recent developments on indole-based anti-cancer drugs and provide insight into the respective structureactivity relationships (SARs) of the compounds. We hope the review will provide a thorough understanding to the reader and guide to developing novel and potent indole-based anticancer agents against drug-sensitive and drug-resistant cancer in the future.

What facets of physical function are most important to adults diagnosed with cancer?

Successful patient-focused drug development involves selecting and measuring outcomes in clinical trials that are important to patients. The U.S. Food & Drug Administration's definition of clinical benefit includes how patients feel, function, or survive. Patients are considered the experts in describing how they feel and function. In cancer trials, patient-reported measures of physical function provide insight into how patients function at baseline, benefit from the interventions being studied, and the impact of treatment side effects. We conducted a qualitative study with adults diagnosed with cancer to describe facets of physical function from their perspective and to identify which facets are most important to this patient population. Using concept elicitation and cognitive interviewing techniques, we conducted semi-structured interviews with 72 adults ≥ 22years of age with cancer who received treatment with an anticancer drug or biologic within six months of the interview. We selected participants using purposive sampling with the aim to elicit diverse experiences regarding how they may interpret and respond to questions related to physical function. Participants were presented with patient-reported outcome (PRO) items representative of PRO measures used in cancer and general populations. Five facets of how physical function relates to activities were defined from the patient perspective: ability, difficulty, limitation, satisfaction, and completion. More than half of the participants indicated that ability was the most important facet of physical function. The next most important were satisfaction (18.3%), limitation (14.1%), difficulty (5.6%), and completion (2.8%). This study demonstrates that we must be more specific about the facets of physical function that we set out to assess when we use PRO measures to describe the patient experience. These results have implications for the specificity of physical function facets when measured in cancer clinical trials.

A Review on Nanostructured Lipid Carriers as Promising Drug Delivery Vehicle to Target Various Cancers via Oral Route: A Step towards “Chemotherapy at Home”

Abstract: Oral drug administration is largely preferred owing to enhanced patient compliance, convenience of self-intake of dose, non-invasiveness, and low manufacturing cost. Cancer is a condition that starts with aberrant cell division at an uncontrolled rate. The clinical effectiveness of many anticancer drugs is limited by their physicochemical characteristics and physiological circumstances in the GI tract. Nanostructured lipid carriers have the potential to enhance the bio-availability of anticancer drugs by entrapping them. The NLCs, by virtue of their nanosize and their biocompatibility, can bypass the first-pass metabolism and be taken up by M cells of Peyer’s patches to deliver the drug to the deeper tumours. The proposed review highlights the potential of NLCs in oral drug delivery for the management of various cancers. It discusses various strategies, method of preparation, mechanism of uptake, and their applications in the treatment of cancer via oral delivery. Further, it explains the recent advances and future perspectives.

The role of HSP40 in cancer: Recent advances.

Heat shock proteins (HSPs) are a family of proteins involved in protein folding and maturation that are expressed by cells in response to stressors including heat shock. Recent studies have demonstrated that HSPs play major roles in carcinogenesis by regulating angiogenesis, cell proliferation, migration, invasion, metastasis, apoptosis, as well as therapy resistance to certain anticancer drugs. Despite being the largest and most diverse subgroup of the HSP family, HSP40 (DNAJ) is an understudied family of co-chaperones. HSP40 family members are also known to be involved in various types of cancers. In this article, we review the involvement of human HSP40 family members in various aspects of cancer biology. In addition, we highlight the possible potential of HSP40 as a tumor biomarker or drug target for improving the prognosis and treatment of cancer patients in the future.

Anticancer activity of synthesized 5-benzyl juglone on selected human cancer cell lines.

Cancer is a malignant disease that causes millions of deaths each year worldwide. As one of the cancer therapeutic strategies, chemotherapy is a means to destroy rapidly dividing cells. The main problem with cancer chemotherapy is the lack of selectivity of conventional chemotherapeutic drugs, leading to toxicity towards normal cells. Therefore, the discovery of anticancer agents with selectivity for fast-growing cancer cells was desirable. In this study, we report the synthesis and identification of the novel 5-benzyl juglone as a potential anticancer agent with selectivity toward certain cancer cell lines. An efficient synthetic method for 5-benzyl juglone has been established. The proliferation of cancer cell lines and a normal cell line treated by the target compound were studied using an MTT assay. In addition, the cell cycle arrest and apoptosis were determined by flow cytometry. Based on the Diels-Alder (D-A) reaction between 3,6-dimethoxy benzyne intermediate with furan, further acid-catalyzed intramolecular rearrangement and CAN-mediated oxidation, a convenient synthesis of 5-benzyl juglone has been achieved with high overall yield. The results from in vitro biological evaluation indicated that the juglone derivative exhibited potent antiproliferative activity against HCT-15 human colorectal cancer cells with an IC50 value of 12.27 μM. It exerted high inhibitory activity toward MCF-7 human breast cancer cells and, to a much lesser extent, to corresponding MCF-10A human breast epithelial normal cells with the IC50 ratio (IC50 in MCF-7 divided by IC50 in MCF-10A) of 0.62. The mechanistic investigations indicated that 5-benzyl juglone could induce cell cycle arrest at the G0/G1 phase and promote apoptosis of HCT-15 cells. The apoptotic effects possibly also contributed to its higher selectivity toward cancer cells than normal cell lines.

Stress relief of chemo illness.

New studies (Tang et al. 2024. J. Exp. Med.https://doi.org/10.1084/jem.20231395) describe a liver stress pathway that is activated by certain chemotherapeutic drugs, which in turn induces a peptide hormone which partially mediates the lower food intake and body weight loss during chemotherapy treatment.

An Insight into Mesoporous Silica Nanoparticles: Ray of Hope for Cancer Management

Abstract: Cancer is one of the fatal diseases leading to a high mortality rate. The conventional formulations available for the treatment of cancer are associated with several drawbacks. The major ones are increased side effects due to improper tumor selectivity, metastasis of cancer cells and development of multi-drug resistance to available chemotherapeutic drugs. The development of nanobased formulations for the treatment of cancer has been found to be beneficial up to a great extent. Mesoporous Silica nanoparticles are one of the nanotechnology-based formulations that could overcome major disadvantages associated with conventional therapy, such as metastasis, multi-drug resistance and side effects to normal cells. MSN-based nanoformulations could provide dual therapeutic effects against cancer cells. Due to their small size and large surface, which could be functionalized by using different targeting and therapeutic moieties, they provide targeted and enhanced drug delivery. This review highlights Mesoporous silica nanoparticles along with their properties, drug encapsulation and various applications in drug delivery, such as multi-targeting strategy, and multimodal combined therapy by using ultrasound, photodynamic etc. In the future, MSN-based nanomedicines could be used to develop other innovative strategies for cancer treatment.

The Development of Organotin(IV) N-Ethyl-N-Benzyldithiocarbamate Complexes: A Study on Their Synthesis, Characterization, and Cytocidal Effects on A549 Cell Line

Background: Organotin(IV) complexes of dithiocarbamate are vital in medicinal chemistry, exhibiting potential in targeting cancer cells due to their unique properties that enhance targeted delivery. This study aimed to synthesize and characterize organotin(IV) N-ethyl-N-benzyldithiocarbamate complexes (ONBDCs) and evaluate their cytotoxicity against A549 cells, which are commonly used as a model for human lung cancer research. Method: The two ONBDC derivatives – ONBDC 1 (dimethyltin(IV) N-ethyl-N-benzyldithiocarbamate) and ONBDC 2 (triphenyltin(IV) N-ethyl-N-benzyldithiocarbamate) – were synthesized via the reaction of tin(IV) chloride with N-ethylbenzylamine in the presence of carbon disulfide. A range of analytical techniques, including elemental analysis, IR spectroscopy, NMR spectroscopy, UV-Vis spectrometry, TGA/DTA analysis, and X-ray crystallography, was conducted to characterize these compounds comprehensively. The cytotoxic effects of ONBDCs against A549 cells were evaluated using MTT assay. Results: Both compounds were synthesized and characterized successfully via elemental and spectroscopies analysis. MTT assay revealed that ONBDC 2 demonstrated remarkable cytotoxicity towards A549 cells, with an IC50 value of 0.52 μM. Additionally, ONBDC 2 displayed significantly higher cytotoxic activity against the A549 cell line when compared to the commercially available chemotherapeutic agent cisplatin (IC50: 32 μM). Conclusion: Thus, it was shown that ONBDC 2 could have important anticancer properties and should be further explored as a top contender for creating improved and specialized cancer treatments.

Dissecting the pleiotropic roles of reactive oxygen species (ROS) in lung cancer: From carcinogenesis towardtherapy.

Lung cancer is a major cause of morbidity and mortality. The specific pulmonary structure to directly connect with ambient air makes it more susceptible to damage from airborne toxins. External oxidative stimuli and endogenous reactive oxygen species (ROS) play a crucial role in promoting lung carcinogenesis and development. The biological properties of higher ROS levels in tumor cells than in normal cells make them more sensitive and vulnerable to ROS injury. Therefore, the strategy of targeting ROS has been proposed for cancer therapy for decades. However, it is embarrassing that countless attempts at ROS-based therapies have had very limited success, and no FDA approval in the anticancer list was mechanistically based on ROS manipulation. Even compared with the untargetable proteins, such as transcription factors, ROS are more difficult to be targeted due to their chemical properties. Thus, the pleiotropic roles of ROS provide therapeutic potential for anticancer drug discovery, while a better dissection of the mechanistic action and signaling pathways is a prerequisite for future breakthroughs. This review discusses the critical roles of ROS in cancer carcinogenesis, ROS-inspired signaling pathways, and ROS-based treatment, exemplified by lung cancer. In particular, an eight considerations rule is proposed for ROS-targeting strategies and drug design and development.

Performance of Green Desymmetrization Methods toward Bioactive Cephalostatin Analogues.

Since the discovery of cephalostatins, which have shown remarkable activity against human cancer cells, they have attracted the attention of researchers to target the synthesis of such impressive, complicated molecules using the green desymmetrization approach. In the current review, we report the progress in the desymmetrization of symmetrical bis-steroidal pyrazines (BSPs) as an approach toward potentially active anti-cancer agents, namely cephalostatins/ ritterazines. The achievement of synthesizing a gram-scaled prodrug with comparable activity to the potent natural cephalostatins using green methods is our primary target. These synthetic methods can be scaled up based on the symmetrical coupling (SC) of two steroidal units of the same type. Our secondary target is the discovery of new green pathways that help in structural reconstruction programming toward the total synthesis of at least one potentially active family member. The strategy is based on functional group interconversions with high flexibility and brevity using green selective methods. The introduction of controlling groups using nontrivial reconstruction methodologies forms the backbone of our work. After certain modifications to the symmetrical BSP starting material, the resulting analogs underwent several chemoselective transformations through three main routes in rings F, D, and C. One of these routes is the chemoselective spiroketal opening (ring-F). The second route was the functionalization of the ∆14,15 bond (ring-D), including chlorination/dechlorination, in addition to epoxidation/ oxygenation processes. Finally, the introduction of the C-11 methoxy group as a directing group on ring-C led to several chemoselective transformations. Moreover, certain transformations on C-12 (ring-C), such as methylenation, followed by hydroboration-oxidation, led to a potentially active analog. The alignment of these results directs us toward the targets. Our efforts culminated in preparing effective anti-cancer prodrugs (8, 24, 30, and 31), which are able to overcome cancer drug resistance (chemoresistance) by inducing the atypical endoplasmic reticulum-mediated apoptosis pathway, which works through the release of Smac/Diablo and the activation of caspase-4.

Advances in chitosan-based drug delivery systems in melanoma: A narrative review.

Melanoma accounts for the minority of skin cancer cases. However, it has the highest mortality rate among the subtypes of skin cancer. At the early stages of the disease, patients show a good prognosis after the surgery, but developing metastases leads to a remarkable drop in patients' 5-year survival rate. Despite the advances made in the therapeutic approaches to this disease, melanoma treatment is still facing several obstacles. Systemic toxicity, water insolubility, instability, lack of proper biodistribution, inadequate cellular penetration, and rapid clearance are some of the challenges that should be addressed in the field of melanoma treatment. While various delivery systems have been developed to circumvent these challenges, chitosan-based delivery platforms have indicated significant success. Chitosan that is produced by the deacetylation of chitin can be formulated into different materials (e.g., nanoparticle, film, and hydrogel) due to its characteristics. Both in vitro and in vivo studies have reported that chitosan-based materials can be used in drug delivery systems while offering a solution for the common problems in this area, such as enhancing biodistribution and skin penetration as well as the sustained release of the drugs. Herein, we reviewed the studies concerning the role of chitosan as a drug delivery system in melanoma and discussed how these drug systems are used for delivering chemotherapeutic drugs (e.g., doxorubicin and paclitaxel), genes (e.g., TRAIL), and RNAs (e.g., miRNA199a and STAT3 siRNA) successfully. Furthermore, we take a look into the role of chitosan-based nanoparticles in neutron capture therapy.

Green Formulation of Descurainia sophia Aqueous Extract Mediated Ag NPs and Determination of Its Anti-Hemangioma Effects

Hemangioma is a common cancer with severe clinical signs. Finding a new anti-hemangioma supplement or drug inside of the chemotherapeutic drug is valuable. We synthesized silver nanoparticles containing Descurainia sophia leaf for investigating the anti-hemangioma, cytotoxicity, and antioxidant effects. Characterization of AgNPs was performed by Field Emission Scanning Electron Microscopy (FE-SEM), UV–Visible Spectroscopy (UV-Vis), and X-Ray diffraction analysis (XRD). The plain peak in the wavelength 449 nm revealed the AgNPs synthesis. TEM and FE-SEM analyses showed that synthesized AgNPs were found to be 16.9 to 48.43 nm mean particle size. For investigating the antioxidant efficacy, the DPPH assay was conducted. AgNPs prevented 50% of DPPH in the dilation of 40 μg/mL. To measure the anti-hemangioma efficacy of AgNPs, MTT assay was applied on SK HEP-1 and HAEND cell lines. AgNPs had high anti-hemangioma efficacy on above tumor cells without any significant toxicity on HUVEC. The best finding of anti-hemangioma properties of AgNPs was seen in the case of the HAEND cell line. This study indicated significant anti-hemangioma and antioxidant potentials of AgNPs containing Descurainia sophia.

Oncogenic alterations of metabolism associated with resistance to chemotherapy.

Metabolic reprogramming in cancer cells is a strategy to meet high proliferation rates, invasion, and metastasis. Also, several researchers indicated that the cellular metabolism changed during the resistance to chemotherapy. Since glycolytic enzymes play a prominent role in these alterations, the ability to reduce resistance to chemotherapy drugs is promising for cancer patients. Oscillating gene expression of these enzymes was involved in the proliferation, invasion, and metastasis of cancer cells. This review discussed the roles of some glycolytic enzymes associated with cancer progression and resistance to chemotherapy in the various cancer types.

Synthesis and Molecular Docking of some new Thiazolidinone and Thiadiazole Derivatives as Anticancer Agents.

New sets of functionalized thiazolidinone and thiadiazole derivatives were synthesized, and their cytotoxicity was evaluated on HepG2, MCF-7, HTC-116, and WI38 cells. The synthetic approach is based on the preparation of 4-(4-acetamidophenyl)thiosemicarbazide (4) and their thiosemicarbazones 5 a-e, which are converted to the corresponding thiazoldin-4-one compounds 6 a-e upon cyclization with ethyl bromoacetate. The thiadiazole compounds 9 and 12 were obtained by reacting 4-(4-acetamidophenyl)thiosemicarbazide with isothiocyanates and/or ethyl 2-cyano-3,3-bis(methylthio)acrylate, respectively. The thiazolidinone compounds 6 c and 6 e exhibited strong cytotoxicity against breast cancer cells, with an IC50 (6.70±0.5 μM) and IC50 (7.51±0.8 μM), respectively, very close to that of doxorubicin (IC50: 4.17±0.2 μM). In addition, the anti-cancer properties of the tested thiazolidinone and thiadiazole scaffolds were further explored by the molecular docking program (MOE)-(PDB Code-1DLS). Compounds 5 d, 5 e, 6 d, 6 e, and 7 have the best binding affinity, ranging from -8.5386 kcal.mol-1 to -8.2830 kcal.mol-1.

Chinese expert consensus on the guidance of anti-tumor drugs for patients with tumor combined chronic kidney disease (2024 edition)

The incidence of malignant tumors has steadily increased year by year in China in recent decades. The emergence of innovative anti-cancer drugs has bolstered the prognosis of cancer patients, making it a chronic disease. Kidney injuries are frequent complications of cancer treatment clinically manifested as acute kidney injury (AKI), chronic kidney disease (CKD), proteinuria, and electrolyte disorders, etc. Although kidney injuries affect up to 50% of the patients, there is a lack of professional management guidance for anti-cancer drug dosage adjustment. The clinical pharmacology branch of the Chinese Medical Association has initiated the "Chinese expert consensus on the guidance of anti-tumor drugs for patients with tumor combined chronic kidney disease (2024 edition)". We unified national multidisciplinary experts to analyze clinical evidence with the Delphi method, and conducted expert interviews and seminars focusing on kidney function assessment, anti-tumor drug dosage adjustment for kidney disease patients. We make recommendations on selection and dose adjustment of anti-tumor drugs (chemotherapy, small molecules and antibodies) according to chemotherapeutic drug classifications, providing practical and feasible scientific guidance for clinicians.

Synergistic effects of quercetin-loaded CoFe2O4@Liposomes regulate DNA damage and apoptosis in MCF-7 cancer cells: based on biophysical magnetic hyperthermia

Introduction Breast cancer (BC) is the most common malignancy in women globally. Significant progress has been made in developing structural nanoparticles (NPs) and formulations for targeted smart drug delivery (SDD) of pharmaceuticals, improving the precision of tumor cell targeting in therapy. Significance Magnetic hyperthermia (MHT) treatment using magneto-liposomes (MLs) has emerged as a promising adjuvant cancer therapy. Methods CoFe2O4 magnetic NPs (MNPs) were conjugated with nanoliposomes to form MLs, and the anticancer drug quercetin (Que) was loaded into MLs, forming Que-MLs composites for antitumor approach. The aim was to prepare Que-MLs for DD systems (DDS) under an alternating magnetic field (AMF), termed chemotherapy/hyperthermia (chemo-HT) techniques. The encapsulation efficiency (EE), drug loading capacity (DL), and drug release (DR) of Que and Que-MLs were evaluated. Results The results confirmed successful Que-loading on the surface of MLs, with an average diameter of 38 nm and efficient encapsulation into MLs (69%). In vitro, experimental results on MCF-7 breast cells using MHT showed high cytotoxic effects of novel Que-MLs on MCF-7 cells. Various analyses, including cytotoxicity, apoptosis, cell migration, western blotting, fluorescence imaging, and cell membrane internalization, were conducted. The Acridine Orange-ethidium bromide double fluorescence test identified 35% early and 55% late apoptosis resulting from Que-MLs under the chemo-HT group. TEM results indicated MCF-7 cell membrane internalization and digestion of Que-MLs, suggesting the presence of early endosome-like vesicles on the cytoplasmic periphery. Conclusions Que-MLs exhibited multi-modal chemo-HT effects, displaying high toxicity against MCF-7 BC cells and showing promise as a potent cytotoxic agent for BC chemotherapy.

Synthesis and Biological Evaluation of Thiazole-Based Fibroblast Growth Factor Receptor-1 Inhibitors.

The Fibroblast Growth Factor Receptor-1 (FGFR-1) is a tyrosine kinase and a validated target for the treatment of different cancer types. Design and synthesis of novel thiazole-based analogues of anticancer agents. Series of 2-aryl-5-methylthiazole analogues linked to structurally variable basic heads were synthesized as novel anticancer agents. Developed compounds were tested for their cytotoxic activities against several cancer cell lines. Many analogues exhibited strong antiproliferative activities against breast cancer cell lines, with higher potency towards the highly metastatic form (MDA-MB-231). Pharmacophoric profiling using an in-house pharmacophore database identified FGFR-1 as a molecular target of active analogues. Synthesized compounds were bio-assayed for their FGFR-1 inhibitory activities and many hits exhibited IC50 values in the low micromolar to nanomolar range The 2-aryl-5-methylthiazole linked to a basic head is a novel chemical scaffold of ATP-competitive inhibitor of FGFR-1 with potential therapeutic activities against different types of cancer.
