Proteins-Based Nanoparticles for Benznidazole Enteric Delivery.

Chagas disease, caused by Trypanosoma cruzi (T. cruzi), affects millions worldwide, particularly in Latin America. Despite its prevalence, treatment options remain limited. Current drugs, such as benznidazole, cause adverse effects possibly due to ineffective administration. In this context, nanoparticles offer a promising solution to target and control drug delivery by leading the effector site and minimizing side effects. This article focuses on zein-casein-based nanoparticles (Bioparticles, BP) coated with Eudragit L100-55 (BP:EU) for enteric delivery of benznidazole. BP:EU structures are synthesized to minimize premature drug release in the stomach, promoting release in the small intestine. Physical characterization confirmed the successful synthesis of BP:EU and their pH-responsive trigger for drug release. These findings suggest that this material can be a promising approach for Chagas disease treatment, addressing challenges in benznidazole delivery that can lead to improved therapeutic responses.

Semisynthetic Ecdysteroid Cinnamate Esters and tert-Butyl Oxime Ether Derivatives with Trypanocidal Activity.

The parasite Trypanosoma cruzi is the causative agent of Chagas disease, a neglected tropical disease that affects the lives of millions of indigenous people in Latin America. As medications to treat Chagas disease are limited to the application of benznidazole and nifurtimox, which are not ideal treatments for the chronic stage of the disease, the search for new antichagasic drug candidates is an important need. Ecdysone has previously been shown to interfere with the life cycle of T. cruzi. Here, we report the biological profiling and subsequent semisynthetic structure optimization of 47 ecdysteroids against T. cruzi with the aim of identifying selective trypanocidal ecdysteroids. Two moderately trypanocidal pharmacophores were identified: ecdysteroids containing a 6-tert-butyl oxime ether and a cinnamic ester moiety. These functional groups were combined into the structures of four new semisynthetic ecdysteroids (44-47), among which 44 exerted potent and selective trypanocidal activity (IC50 < 2 μM). Cellular infection assays showed that ecdysteroid 44 potently and efficiently inhibited amastigote replication as determined by trypomastigote release after cellular infection with an IC50 of 2.7 ± 0.1 μM. The compound was similarly potent to benznidazole (IC50 = 3.8 ± 0.7 μM) and more than 5-fold more cytotoxic toward T. cruzi over RAW264.7 host macrophages. Overall, the ecdysteroid cinnamate ester 44 is a novel trypanocidal lead structure that needs to be further characterized in follow-up studies.

Anti-staphylococcal, antibiofilm and trypanocidal activities of CrataBL encapsulated into liposomes: Lectin with potential against infectious diseases

The present study aimed to evaluate the anti-staphylococcal, antibiofilm, cytotoxicity and trypanocidal activity, mechanisms of parasite death and immunomodulatory effect of CrataBL encapsulated into liposomes (CrataBL-Lipo). CrataBL-Lipo were prepared by the freeze-thaw technique and characterized. Anti-staphylococcal and antibiofilm activities of CrataBL and CrataBL-Lipo were evaluated against standard and clinical strains of Staphylococcus aureus susceptible and resistant. Thus, broth microdilution method was performed to determine the Minimum Inhibitory Concentration (MIC). Antibiofilm activity at subinhibitory concentrations was evaluated using the crystal violet staining method. Cytotoxicity of CrataBL-Lipo was verified in L929 fibroblasts and J774A.1 macrophages by determining the inhibitory concentration necessary to kill 50 % of cells (IC50). Trypanocidal activities of CrataBL-Lipo was evaluated in Trypanosoma cruzi and the efficacy was expressed as the concentration necessary to kill 50 % of parasites (EC50). The mechanisms of parasite death and immunomodulatory effect of CrataBL-Lipo were evaluated using flow cytometry analysis. CrataBL-Lipo presented Ø of 101.9 ± 1.3 nm (PDI = 0.245), ζ of +33.8 ± 1.3 mV and %EE = 80 ± 0.84 %. CrataBL-Lipo presented anti-staphylococcal activity (MIC = 0.56 mg/mL to 0.72 mg/mL). CrataBL-Lipo inhibited 45.4 %–75.6 % of biofilm formation. No cytotoxicity of CrataBL-Lipo was found (IC50 > 100 mg/L). CrataBL-Lipo presented EC50 of 1.1 mg/L, presenting autophagy, apoptosis and necrosis as death profile. In addition, CrataBL-Lipo reduced the production of IL-10 and TNF-α levels, causing an immunomodulatory effect. CrataBL-Lipo has a therapeutic potential for the treatment of staphylococcal infections and Chagas disease exhibiting a high degree of selectivity for the microorganism, and immunomodulatory properties.

1,3,4-oxadiazoles as inhibitors of the atypical member of the BET family bromodomain factor 3 from Trypanosoma cruzi (TcBDF3).

Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, affects millions globally, with increasing urban cases outside of Latin America. Treatment is based on two compounds, namely, benznidazole (BZ) and nifurtimox, but chronic cases pose several challenges. Targeting lysine acetylation, particularly bromodomain-containing proteins, shows promise as a novel antiparasitic target. Our research focuses on TcBDF3, a cytoplasmic protein, which is crucial for parasite differentiation that recognizes acetylated alpha-tubulin. In our previous study, A1B4 was identified as a high-affinity binder of TcBDF3, showing significant trypanocidal activity with low host toxicity in vitro. In this report, the binding of TcBDF3 to A1B4 was validated using differential scanning fluorescence, fluorescence polarization, and molecular modeling, confirming its specific interaction. Additionally, two new 1,3,4-oxadiazoles derived from A1B4 were identified, which exhibited improved trypanocide activity and cytotoxicity profiles. Furthermore, TcBDF3 was classified for the first time as an atypical divergent member of the bromodomain extraterminal family found in protists and plants. These results make TcBDF3 a unique target due to its localization and known functions not shared with higher eukaryotes, which holds promise for Chagas disease treatment.

American trypanosomiasis

Objective: Due to the importance of Chagas disease as a public health problem in Brazil, this study aims to present a review of the epidemiological, treatment and control aspects of Chagas disease in Brazil. Literature review: American trypanosomiasis, popularly known as Chagas disease, is considered one of the most important neglected diseases in Latin America. The etiologic agent is Trypanosoma cruzi, which is primarily transmitted by hematofagous insects, known as kissing bugs, that belong to the subfamily Triatominae. Besides the primary form of transmission, other forms of transmission have been discovered over the years, such as oral, congenital, blood transfusion, transplant and accidental transmission. It is difficult to diagnose it in the acute phase because it presents generic and non-specific symptoms. It is usually diagnosed in the chronic stage, when the digestive and cardiac systems may be compromised. Since the end of 1960, treatment has been restricted to two drugs, but they are not so effective, and alternative medicines are necessary to improve the treatment and life quality of patients. Final considerations: In order to reduce Chagas disease transmission, Latin American countries, especially Brazil, must improve the surveillance system and provide primary care to the population.

Electrochemical Halogenation of Naphthoquinones: A Modular and Sustainable Strategy towards Trypanocidal Compounds.

An eco-friendly electrochemical halogenation of 2-amino-1,4-naphthoquinones has been developed. The new mild and energy efficient methodology comprises sustainable features like oxidant free and double role of the halogen source as electrolyte, originating twenty-six amino-halogenated naphthoquinoidal derivatives in good yields under mild conditions. This novel methodology permitted access to new potent trypanocidal prototypes, where six compounds were more active than benznidazole, the current market drug used in the treatment of Chagas Disease.

Cyclodextrin Complexes for the Treatment of Chagas Disease: A Literature Review.

Cyclodextrins are ring-shaped sugars used as additives in medications to improve solubility, stability, and sensory characteristics. Despite being widespread, Chagas disease is neglected because of the limitations of available medications. This study aims to review the compounds used in the formation of inclusion complexes for the treatment of Chagas disease, analyzing the incorporated compounds and advancements in related studies. The databases consulted include Scielo, Scopus, ScienceDirect, PubMed, LILACS, and Embase. The keywords used were "cyclodextrin AND Chagas AND disease" and "cyclodextrin complex against Trypanosoma cruzi". Additionally, a statistical analysis of studies on Chagas disease over the last five years was conducted, highlighting the importance of research in this area. This review focused on articles that emphasize how cyclodextrins can improve the bioavailability, therapeutic action, toxicity, and solubility of medications. Initially, 380 articles were identified with the keyword "cyclodextrin AND Chagas disease"; 356 were excluded for not being directly related to the topic, using the keyword "cyclodextrin complex against Trypanosoma cruzi". Over the last five years, a total of 13,075 studies on Chagas disease treatment were found in our literature analysis. The studies also showed interest in molecules derived from natural products and vegetable oils. Research on cyclodextrins, particularly in the context of Chagas disease treatment, has advanced significantly, with studies highlighting the efficacy of molecules in cyclodextrin complexes and indicating promising advances in disease treatment.

Adverse events associated with benznidazole treatment for Chagas disease in children and adults.

Chagas disease (ChD) affects approximately 7 million people in Latin America, with benznidazole being the most commonly used treatment. Data from a retrospective cohort study in Argentina, covering January 1980 to July 2019, was reanalysed to identify and characterize benznidazole-related adverse drug reactions (ADRs). The study included 518 patients: 449 children and 69 adults (median age in children: 4years; adults: 25 years; age ranges: 1month-17.75 years and 18-59 years, respectively). The median benznidazole doses received were 6.6mg/kg/day for at least 60 days in children and 5.6mg/kg/day for a median of 31 days in adults. Overall, 29.34% (152/518) of patients developed benznidazole-related ADRs, with an incidence of 25.83% (116/449) in children and 52.17% (36/69) in adults (odds ratio [OR] = 0.32, 95% confidence interval [CI] = 0.19-0.54, P < .001). The incidence rate was 177 cases per 1000 person-years (95% CI = 145-214) in children and 537 per 1000 person-years (95% CI = 360-771) in adults. There were 240 ADRs identified, primarily mild to moderate. Severe ADRs occurred in 1.11% (5/449) of children and 1.45% (1/69) of adults. The skin was the most affected system. A total of 10.23% (53/518) of patients discontinued treatment. More adults than children discontinued treatment (OR = 3.36, 95% CI = 1.7-6.4, P < .001). Although 29.34% of patients experienced ADRs, most were mild to moderate, indicating a manageable safety profile for benznidazole. While optimized dosing schedules and new drugs are needed, avoiding benznidazole solely due to safety concerns is not justified.

Chagas Disease: Epidemiology, Diagnosis, and Treatment.

This review seeks to describe the updates in the literature - particularly with regards to the epidemiology and diagnosis of Chagas disease. Additionally, this paper describes updates to the antiparasitic treatment for Chagas disease. With regards to changing epidemiology, autochthonous cases are being found within the USA in addition to Latin America. Additionally, there appears to be more intermixing of discrete typing units-meaning, they are not confined to specific geographic regions. Screening for Chagas disease is recommended in persons who lived in areas with endemic Chagas, persons wtih family member diagnosed with Chagas Disease, persons who have lived in homes of natural material in Latin America, and persons with history of kissing bug bites. Treatment for the parasitic infection remains limited to benznidazole and nifurtimox, and the role of these treatments in Chagas cardiomyopathy has not yet been definitively defined. Finally, indications for and management of heart transplant in the setting of Chagas disease are discussed. Use of antiparasitics during chronic chagas disease should be further explored. Additionally, future research identifying other markers of infection would be valuable to defining cure from infection.

Treatment options applied to the preclinical studies using animal models for Chagas Disease: a systematic review and meta-analysis

Background Chagas disease (CD) is a neglected tropical disease endemic to Latin America, has emerged as a global health concern due to the migration of infected individuals. With its epidemiological complexity, by difficulty to obtain appropriate diagnoses and poor treatment, the search for novel therapeutic options remains. Methods In this context, we conducted a systematic review and meta-analysis of preclinical studies employing animal models to verify the progress in CD treatment. We searched the PubMed database for CD treatment studies published between 1990 and 2023, adhering to the PRISMA guidelines. Results Twelve papers met the inclusion criteria. The findings indicate that the fifteen treatment alternatives examined, mainly between 2010 and 2014, demonstrated efficacy in experimental CD models, evidenced by significant parasitemia reduction. Bis-triazole DO870 and VNI were effective in the acute and chronic phases, respectively. However, of these emerging therapies, only posaconazole and fexinidazole have progressed to clinical trials, yielding unsatisfactory outcomes as CD monotherapies Conclusions This meta-analysis highlights the existence of promising new drug candidates for CD treatment, but most remain in the preclinical stages. Those that reached clinical trials did not demonstrate optimal results, underscoring the ongoing challenges in CD therapy. Collaborative efforts among the academic community, pharmaceutical industries, funding agencies, and government agencies are urgently needed to accelerate the development of more effective medications against CD.

Organic solvent-free benznidazole nanosuspension as an approach to a novel pediatric formulation for Chagas disease.

Aim: Benznidazole (BNZ), a class-II drug, is the primary treatment for Chagas disease, but its low aqueous solubility presents challenges in formulation and efficacy. Nanosuspensions (NS) could potentially address these issues.Methods: BNZ-NS were prepared using a simple, organic solvents-free nano-milling approach. Physicochemical characterizations were conducted on both NS and lyophilized solid-state BNZ-nanocrystals (NC).Results: BNZ-NS exhibited particle size <500nm, an acceptable polydispersity index (0.23), high Z-potential, and physical stability for at least 90days. BNZ-NC showed tenfold higher solubility than pure BNZ. Dissolution assays revealed rapid BNZ-NS dissolution. BNZ-NC demonstrated biocompatibility on an eukaryotic cell and enhanced BNZ efficacy against trypomastigotes of Trypanosoma cruzi.Conclusion: BNZ-NS offers a promising alternative, overcoming limitations associated with BNZ for optimized pharmacotherapy.

Treatments and the Perspectives of Developing a Vaccine for Chagas Disease.

Chagas disease (CD) treatment and vaccine development are critical due to the significant health burden caused by the disease, especially in Latin America. Current treatments include benznidazole and nifurtimox, which are most effective in the acute phase of the disease but less so in the chronic phase, often with significant side effects. Here, using the available literature, we summarize the progress in vaccine development and new treatments that promise to reduce CD incidence and improve the quality of life for those at risk, particularly in endemic regions. New treatment options, such as posaconazole and fexinidazole, are being explored to improve efficacy and reduce adverse effects. Vaccine development for CD remains a high priority. The complex life stages and genetic diversity of Trypanosoma cruzi present challenges, but several promising vaccine candidates are under investigation. These efforts focus on stimulating a protective immune response through various innovative approaches.

Causalidade e Gravidade das Reações Adversas e Alterações Laboratoriais ao Tratamento com Benznidazol em Pacientes com Doença de Chagas Crônica

Abstract Background Chagas disease (CD) is a serious public health problem in Latin America. Benznidazole (BNZ) is used for the treatment of CD and, despite its wide use, little information is available about its toxicity and mechanisms of adverse drug reactions (ADR). Objectives To identify and classify clinical and laboratory adverse reactions caused by BNZ in terms of causality and severity. Methods Prospective cohort study from January 2018 to December 2021. Treatment follow-up included visits and biochemical tests (complete blood count, liver and kidney function tests) before, during and after treatment. ADR were classified according to causality and severity. In the statistical analysis, the significance level was set at p&lt;0.05. Results Forty patients with chronic CD were included. A high prevalence of ADR was observed 161 ADR in 30 patients [90%]; of these, 104 (64.6%) were classified as possible and 57 (35.4%) as probable. The ADR were classified as moderate and mild. Of the 40 patients, nine (22.5%) discontinued treatment. ADR associated with treatment discontinuation and interventions were those that affected the dermatological system, central and peripheral nervous system and sense organs such as ageusia. Mild hematological and biochemical changes such as lymphopenia were observed after 30 days of treatment. Conclusion Many patients were able to complete the treatment even with ADR, which can be attributed to the successful follow-up strategy with symptomatic treatment and counseling, leading to patient’s awareness of symptoms and treatment adherence.

A guide for the generation of repositories of clinical samples for research on Chagas disease.

Chagas disease, caused by the parasite Trypanosoma cruzi, affects over 6 million people, mainly in Latin America. Two different clinical phases, acute and chronic, are recognised. Currently, 2 anti-parasitic drugs are available to treat the disease (nifurtimox and benznidazole), but diagnostic methods require of a relatively complex infrastructure and trained personnel, limiting its widespread use in endemic areas, and the access of patients to treatment. New diagnostic methods, such as rapid tests (RDTs) to diagnose chronic Chagas disease, or loop-mediated isothermal amplification (LAMP), to detect acute infections, represent valuable alternatives, but the parasite's remarkable genetic diversity might make its implementation difficult. Furthermore, determining the efficacy of Chagas disease treatment is complicated, given the slow reversion of serological anti-T. cruzi antibody reactivity, which may even take decades to occur. New biomarkers to evaluate early therapeutic efficacy, as well as diagnostic tests able to detect the wide variety of circulating genotypes, are therefore, urgently required. To carry out studies that address these needs, high-quality and traceable samples from T. cruzi-infected individuals with different geographical backgrounds, along with associated clinical and epidemiological data, are necessary. This work describes the framework for the creation of such repositories, following standardised and uniform protocols, and considering the ethical, technical, and logistic aspects of the process. The manual can be adapted according to the resources of each laboratory, to guarantee that samples are obtained in a reproducible way, favouring the exchange of data among different work groups, and their generalizable evaluation and analysis. The main objective of this is to accelerate the development of new diagnostic methods and the identification of biomarkers for Chagas disease.

Crystal structure of glycerol kinase from Trypanosoma cruzi, a potential molecular target in Chagas disease.

Chagas disease is a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi. It bears a significant global health burden with limited treatment options, thus calling for the development of new and effective drugs. Certain trypanosomal metabolic enzymes have been suggested to be druggable and valid for subsequent inhibition. In this study, the crystal structure of glycerol kinase from T. cruzi, a key enzyme in glycerol metabolism in this parasite, is presented. Structural analysis allowed a detailed description of the glycerol binding pocket, while comparative assessment pinpointed a potential regulatory site which may serve as a target for selective inhibition. These findings advance the understanding of glycerol metabolism in eukaryotes and provide a solid basis for the future treatment of Chagas disease.

Efficacy of a Zn-based metalorganic framework doped with benznidazole on acute experimental Trypanosoma cruzi infection.

Metal-Organic Frameworks (MOFs) have been shown to enhance the activity of encapsulated compounds by facilitating their passage across cell membranes, thereby enabling controlled and selective release. This study investigates the efficacy of BNZ@Zn-MOFs against the acute phase of Trypanosoma cruzi infection in a mouse model. The particles were synthesized by electroelution (EL), doped with BZN via mechanochemistry, and characterized using scanning electron microscopy (SEM), infrared spectroscopy (FTIR), and X-ray diffraction (XRD). BNZ@Zn-MOFs released 80% of the encapsulated BZN within 3h, demonstrating no cytotoxicity in NIH-3T3 and HeLa cells. Furthermore, in a model of acute experimental T. cruzi-infection in BALB/c mice, the delivery system exhibited antiparasitic activity at a significantly lower BZN concentration compared to free BZN treatment. PCR analysis of treated mice revealed no parasite DNA in their tissues, and hematoxylin-eosin staining showed no apparent damage to tissue architecture. Additionally, serum levels of liver function enzymes remained unchanged, indicating no adverse effects on liver function. This delivery system, utilizing suboptimal BZN doses, enables the preservation of drug activity while potentially facilitating a substantial decrease in side effects associated with Chagas disease treatment.

Phase 2 pilot trial to optimise pharmacometric evaluations in Chagas disease (CHARM: CHAgas disease PharMacometrics)

Chagas disease is a neglected disease caused by Trypanosoma cruzi that currently affects about 7 million people in the Americas and the American diaspora. Only two drugs are available to treat Chagas disease, both are associated with a high incidence of adverse events, particularly in adults, and they are also complex to administer. New treatments are needed urgently, but there is no established method of evaluating new drugs. We describe the study protocol for a pilot phase 2 descriptive observational study of parasite dynamics within the host, followed by a randomised evaluation of the pharmacokinetic-pharmacodynamic properties of subcurative doses of anti-chagasic drugs in patients with chronic Chagas disease. This study is divided into three stages. The general objective of the study is to characterise the dynamics of the parasite within the host at steady state and the pharmacokinetic-pharmacodynamic relationships for each of the three drugs studied. This is based on characterising the structure and parameters of a pharmacodynamic model of parasite turnover within the host. Each stage of the study targets specific key parameters in the pharmacodynamic model of parasite dynamics (both the blood stage and the tissue stage) for individual research participants. The primary outcome measure for all three stages is blood-stage parasite density, measured by quantitative PCR. Upon completion, research participants will receive definitive treatment for Chagas disease in accordance with national guidelines. Registration ISRCTN (ISRCTN26467068; 01/07/2021).

Evaluation of the interaction between new trypanocide 1,2,4-triazolo-3-thiones with human serum albumin

There is a strong demand for the development of new drugs for the treatment of Chagas disease, a neglected tropical disease. This work investigates human serum albumin (HSA) interaction with a new series of 1,2,4-triazolo-3-thiones derived from piperine (1b, 1c, 1d, and 1e), which were demonstrated by our group to present trypanocide activity in the low micromolar range. The study was carried out by spectroscopic techniques, including UV–vis absorption, circular dichroism, steady-state and time-resolved fluorescence combined with theoretical calculations (molecular docking). The binding is spontaneous (ΔG° < 0) and strong (Ka ≈ 105 M−1), resulting in a non-conventional ground state association (there is a combination of static and dynamic quenching mechanisms). The positive values of ΔH° and ΔS° are indicative that the binding is entropically driven and suggest that the interaction between the compounds and HSA is governed by hydrophobic interactions. Interestingly, competitive binding results show that compounds containing a cyclohexyl substituent at N4 (1c and 1e) bind preferentially to Sudlow’s site I, whereas compounds containing a phenylethyl substituent at N4 (1b and 1d) bind preferentially to Sudlow’s site II. Docking results indicate that the interaction profiles of 1c and 1e to Sudlow’s site I are quite similar, as are those of 1b and 1d in Sudlow’s site II. In all cases, the interactions are predominantly hydrophobic, in accordance with the thermodynamic data. The favorable interaction profiles with HSA should have a positive effect on the pharmacokinetics of the trypanocide piperine derivatives and probably a major influence on their in vivo efficacy.

Benznidazole-Loaded Polymeric Nanoparticles for Oral Chemotherapeutic Treatment of Chagas Disease.

Chagas disease (CD) is a worldwide public health problem. Benznidazole (BZ) is the drug used to treat it. However, in its commercial formulation, it has significant side effects and is less effective in the chronic phase of the infection. The development of particulate systems containing BZ is therefore being promoted. The objective of this investigation was to develop polymeric nanoparticles loaded with BZ and examine their trypanocidal impact in vitro. Two formulas (BNP1 and BNP2) were produced through double emulsification and freeze drying. Subsequent to physicochemical and morphological assessment, both formulations exhibited adequate yield, average particle diameter, and zeta potential for oral administration. Cell viability was assessed in H9C2 and RAW 264.7 cells in vitro, revealing no cytotoxicity in cardiomyocytes or detrimental effects in macrophages at specific concentrations. BNP1 and BNP2 enhanced the effect of BZ within 48 h using a treatment of 3.90 μg/mL. The formulations notably improved NO reduction, particularly BNP2. The findings imply that the compositions are suitable for preclinical research, underscoring their potential as substitutes for treating CD. This study aids the quest for new BZ formulations, which are essential in light of the disregard for the treatment of CD and the unfavorable effects associated with its commercial product.
