Introduction Cancer stem cells (CSCs) drive the initiation, maintenance, and therapy response of breast tumors. CD49f is expressed in breast CSCs and functions in the maintenance of stemness. Thus, blockade of CD49f is a potential therapeutic approach for targeting breast CSCs. In the present study, we aimed to repurpose drugs as CD49f antagonists. Materials and methods We performed consensus molecular docking using a subdomain of CD49f that is critical for heterodimerization and a collection of pharmochemicals clinically tested. Molecular dynamics simulations were employed to further characterize drug-target binding. Using MDA-MB-231 cells, we evaluated the effects of potential CD49f antagonists on 1) cell adhesion to laminin; 2) mammosphere formation; and 3) cell viability. We analyzed the effects of the drug with better CSC-selectivity on the activation of CD49f-downstream signaling by Western blot (WB) and co-immunoprecipitation. Expressions of the stem cell markers CD44 and SOX2 were analyzed by flow cytometry and WB, respectively. Transactivation of SOX2 promoter was evaluated by luciferase reporter assays. Changes in the number of CSCs were assessed by limiting-dilution xenotransplantation. Results Pranlukast, a drug used to treat asthma, bound to CD49f in silico and inhibited the adhesion of CD49f+ MDA-MB-231 cells to laminin, indicating that it antagonizes CD49f-containing integrins. Molecular dynamics analysis showed that pranlukast binding induces conformational changes in CD49f that affect its interaction with β1-integrin subunit and constrained the conformational dynamics of the heterodimer. Pranlukast decreased the clonogenicity of breast cancer cells on mammosphere formation assay but had no impact on the viability of bulk tumor cells. Brief exposure of MDA-MB-231 cells to pranlukast altered CD49f-dependent signaling, reducing focal adhesion kinase (FAK) and phosphatidylinositol 3-kinase (PI3K) activation. Further, pranlukast-treated cells showed decreased CD44 and SOX2 expression, SOX2 promoter transactivation, and in vivo tumorigenicity, supporting that this drug reduces the frequency of CSC. Conclusion Our results support the function of pranlukast as a CD49f antagonist that reduces the CSC population in triple-negative breast cancer cells. The pharmacokinetics and toxicology of this drug have already been established, rendering a potential adjuvant therapy for breast cancer patients.

Background: The 2020 pandemic of SARS-CoV-2 causing COVID-19 disease is an unprecedented global emergency. COVID-19 appears to be a disease with an early phase where the virus replicates, coinciding with first presentation of symptoms, followed by a later ‘inflammatory’ phase which results in severe disease in some individuals. It is known from other rapidly progressive infections such as sepsis and influenza that early treatment with antimicrobials is associated with better outcome. The hypothesis is that this holds for COVID-19 and that early antiviral treatment may prevent progression to the later phase of the disease.Methods: Trial design: Phase IIA randomised, double-blind, 2 x 2 design, placebo-controlled, interventional trial.Randomisation: Participants will be randomised 1:1 by stratification, with the following factors: age (≤ 55 vs > 55 years old), gender, obesity (BMI Discussion: We propose to conduct a proof-of-principle placebo-controlled clinical trial of favipiravir plus or minus nitazoxanide in health workers, their household members and patients treated at the Mexican Social Security Institute (IMSS) facilities. Participants with or without symptomatic COVID-19 or tested positive will be assigned to receive favipiravir plus nitazoxanide or favipiravir plus nitazoxanide placebo. The primary outcome will be the difference in the amount of virus (‘viral load’) in the upper respiratory tract after 5 days of therapy. Secondary outcomes will include hospitalization, major morbidity and mortality, pharmacokinetics, and impact of antiviral therapy on viral genetic mutation rate. If favipiravir with nitazoxanide demonstrates important antiviral effects without significant toxicity, there will be a strong case for a larger trial in people at high risk of hospitalization or intensive care admission, for example older patients and/or those with comorbidities and with early diseaseTrial registration: Register at Clinical Trials: NCT04918927 dated June 9th, 2021.

Chagas disease (CD), or American trypanosomiasis, causes more than 10,000 deaths per year in the Americas. Current medical therapy for CD has low efficacy in the chronic phase of the disease and serious adverse effects, therefore, it is necessary to search for new pharmacological treatments. In this work, the ZINC15 database was filtered using the N-acylhydrazone moiety and a subsequent structure-based virtual screening was performed using the cruzain enzyme of Trypanosoma cruzi to predict new potential cruzain inhibitors. After a rational selection process, four compounds, Z2 (ZINC9873043), Z3 (ZINC9870651), Z5 (ZINC9715287), and Z6 (ZINC9861447), were chosen to evaluate their in vitro trypanocidal activity and enzyme inhibition. Compound Z5 showed the best trypanocidal activity against epimatigote (IC50 = 36.26 &plusmn, 9.9 &mu, M) and trypomastigote (IC50 = 166.21 &plusmn, 14.5 &mu, M and 185.1 &plusmn, 8.5 &mu, M on NINOA and INC-5 strains, respectively) forms of Trypanosoma cruzi. In addition, Z5 showed a better inhibitory effect on Trypanosoma cruzi proteases than S1 (STK552090, 8-chloro-N-(3-morpholinopropyl)-5H-pyrimido[5,4-b]-indol-4-amine), a known cruzain inhibitor. This study encourages the use of computational tools for the rational search for trypanocidal drugs.

Breast cancer is the second cause of cancer death in women and the large majority of those deaths are due to drug resistance and/or recurrence. The cancer stem cell (CSC) model suggests that tumor stem-like cells play key roles in resistance and recurrence in breast cancer patients. Thus, CSCs have been pointed as targets for new anti-cancer therapies. CD49f is an integrin subunit that participates in the CSC-niche interaction. Knock-down of CD49f in breast cancer cells impairs mammosphere formation in vitro and tumorigenesis in vivo, suggesting that this protein is needed for maintenance of stemness. Aiming to target breast CSC, we used consensus docking to select potential CD49f antagonists from a collection of 13,000+ drugs with previous clinical evaluations. Seven compounds with the lowest consensus Z score were selected for in vitro biological validation. Cell adhesion assays showed that four of the selected drugs (5193, 1382, 7631, and 12723) decrease the binding of CD49f+ MDA-MB-231 breast cancer cells to laminin, suggesting that those compounds antagonize the receptor. Mammosphere formation assays showed that compounds 5193, 1382, and 12723 limit the clonogenic capability of CD49f+ breast cancer cells in vitro. Compound 5193 was highly toxic in 2D cell viability assays. On the other hand, the clonogenic impairment produced by compounds 1382 and 12723 is independent of bulk cell line cytotoxicity, suggesting a direct impact on the CSC pool. The analyses of the effect of these drugs on the expression of breast CSC markers and CD49f-activated pathways are on their way. Thus, we have identified some drugs that might be repurposed to target breast CSC. Since the pharmacokinetics and toxicology of those drugs is known, they could easily be ready for clinical trials. We demonstrated that in silico screening is useful to identify antagonists of receptors with relevant roles in breast CSC biology.

Polyamines are ubiquitous polycationic compounds that are highly charged at physiological pH. While passing through the epididymis, sperm lose their capacity to synthesize the polyamines and, upon ejaculation, again come into contact with the polyamines contained in the seminal fluid, unleashing physiological events that improve sperm motility and capacitation. In the present work, we hypothesize about the influence of polyamines, namely, spermine, spermidine, and putrescine, on the activity of sperm channels, evaluating the intracellular concentrations of chloride [Cl&minus, ]i, calcium [Ca2+]i, sodium [Na+]i, potassium [K+]i, the membrane Vm, and pHi. The aim of this is to identify the possible regulatory mechanisms mediated by the polyamines on sperm-specific channels under capacitation and non-capacitation conditions. The results showed that the presence of polyamines did not directly influence the activity of calcium and chloride channels. However, the results suggested an interaction of polyamines with sodium and potassium channels, which may contribute to the membrane Vm during capacitation. In addition, alkalization of the pHi revealed the possible activation of sperm-specific Na+/H+ exchangers (NHEs) by the increased levels of cyclic AMP (cAMP), which were produced by soluble adenylate cyclase (sAC) and interact with the polyamines, evidence that is supported by in silico analysis.

CD44 is a receptor for hyaluronan (HA) that promotes epithelial-to-mesenchymal transition (EMT), induces cancer stem cell (CSC) expansion, and favors metastasis. Thus, CD44 is a target for the development of antineoplastic agents. In order to repurpose drugs as CD44 antagonists, we performed consensus-docking studies using the HA-binding domain of CD44 and 11,421 molecules. Drugs that performed best in docking were examined in molecular dynamics simulations, identifying etoposide as a potential CD44 antagonist. Ligand competition and cell adhesion assays in MDA-MB-231 cells demonstrated that etoposide decreased cell binding to HA as effectively as a blocking antibody. Etoposide-treated MDA-MB-231 cells developed an epithelial morphology; increased their expression of E-cadherin; and reduced their levels of EMT-associated genes and cell migration. By gene expression analysis, etoposide reverted an EMT signature similarly to CD44 knockdown, whereas other topoisomerase II (TOP2) inhibitors did not. Moreover, etoposide decreased the proportion of CD44+/CD24− cells, lowered chemoresistance, and blocked mammosphere formation. Our data indicate that etoposide blocks CD44 activation, impairing key cellular functions that drive malignancy, thus rendering it a candidate for further translational studies and a potential lead compound in the development of new CD44 antagonists.

The present study evaluates the possible antifertility effect of aqueous crude extract (OBACE) of Echeveria gibbiflora, a plant that belongs to the crassulaceae family, used in traditional Mexican medicine as a vaginal post coital rinse to prevent pregnancy and shown to have an immobilization/agglutination effect on sperm of different mammal species. We evaluated the effect of OBACE on functional parameters of mouse sperm, such as viability, capacitation, and acrosome reaction. In addition, due to the high concentrations of calcium bis-(hydrogen-1-malate) hexahydrate [Ca (C4H5O5)2•6H2O] present in this plant extract, we evaluated its effect on Ca(2+) influx in mouse sperm under capacitating conditions. Moreover, we determined the acute toxicity of OBACE and its in vivo effect in mouse sperm motility administering a single daily dose of 50 and 100 mg/kg during seven days, intraperitoneally. The sperm viability was not affected by the presence of different concentrations of OBACE, however, the capacitation and acrosome reaction suffered a significant decrease in a concentration-dependent manner, coinciding with the reduction of Ca(2+) influx. Furthermore, OBACE displayed an LD50 of 3,784.42 mg/kg and can be classified as a low toxic substance. Also, in vivo OBACE showed an inhibition of total and progressive motility on mouse sperm alongside a significant decrease of motility kinematic parameters and IVF rates. The results confirm the antifertility effect of this plant used in Mexican folk medicine. Further study on OBACE as a possible contraceptive treatment is warranted because of its activity and low in vivo toxicity.ALH: lateral amplitude; AP: acid phosphatase; BCF: beat frequency; BSA: bovine serum albumine; CTC: chlortetracycline; FDA: fluorescein diacetate; Fura-2 AM: fura-2-acetoxymethyl ester; HIV: human immunodeficiency virus; IVF: in vitro fertilization; OBACE: aqueous crude extract of Echeveria gibbiflora; PI: propidum iodide; SN: supernatant; VAP: average path velocity; VCL: track speed; VSL: straight line velocity.

The trypanocidal activity of N-allyl (NAOx) and N-propyl (NPOx) oxamates and that of the ethyl esters ofN-allyl (Et-NAOx) and N-propyl (Et-NPOx) oxamates were tested on cultured epimastigotes (in vitro) and murine trypanosomiasis (in vivo) using five different T. cruzi strains. NAOx and NPOx did not penetrate intact epimastigotes and therefore we were not able to detect any trypanocidal effect with these oxamates. Whereas the ethyl esters (Et-NAOx and Et-NPOx), acting as prodrugs, exhibited in vitro and in vivo trypanocidal activity on the five tested T. cruzi strains. On the contrary, when Nifurtimox and Benznidazole used as reference drugs were tested, we found that only three of the five tested T cruzi strains were affected, whereas the other two strains, Miguz and Compostela, were resistant to the in vitro and in vivo trypanocidal activity of these compounds.

Este proyecto busca mejorar la imagen que tiene el proveedor de pinturas dentro de una ensambladora de vehículos mediante la mejora de una de las características de calidad más importantes del acabado final del producto: la nivelación/piel naranja. Se pretende entonces aplicar la metodología Seis Sigma mediante el ciclo DMAIC (Definir, Medir, Analizar, Mejora y Controla) propio de la misma, al proceso de aplicación de fondo dentro de la ensambladora para mejorar la capacidad de proceso de la nivelación vertical por ser en al actualidad un factor crítico de rechazo que además está afectando económicamente al proveedor. Una vez definido el alcance del proyecto y las especificaciones del cliente, se realizan mediciones tanto de la variable objeto de estudio para definir la capacidad de proceso actual y la mejora, como de las que pueden afectarlo. Posteriormente, un análisis estadístico y la voz del cliente establecen puntos de mejora que se prueban para corroborar su eficacia dentro del proceso y en caso de obtener los resultados esperados, se determinan métodos de control que aseguren la permanencia de la mejora en el tiempo. Inicialmente se estableció una mejora del 30% en el Cpk del proceso debido a que la aplicación de pintura es un proceso manual en el que intervienen muchas variables; sin embargo mediante la solución propuesta se obtuvo una mejora del 80% con lo que se esperan ahorros para el proveedor. / Abstract. This project seeks to improve the paint supplier’s image within a vehicle assembly plant by enhancing one of the most important quality characteristics of the product: leveling/orange peel. The objective is to apply the Six Sigma methodology, through the DMAIC cycle (Define, Measure, Analyze, Improve and Control), to primer application procedures in order to improve the process capability of vertical leveling which today is a critical rejection factor that also affects the supplier economically. Once the project scope and customer specifications are defined, the main variable is measured to determine the current process capability and to establish the improvement goal; it is also important to measure inputs to know which variables can affect the process. Subsequently, a statistical analysis and the voice of the costumer (VOC) lead to improvements that are tested to verify their effectiveness in the process. Finally, control methods are identified to ensure the improvement’s permanence over time. At fist it was established a 30% improvement in the process Cpk because paint application is a manual process involving many variables, but an 80% improvement was obtained with the proposed solution that aims to achieve savings of USD $ 132,659 for the supplier.
