1. Direct Assay to Evaluate Phosphoenolpyruvate Carboxykinase Activity
Phosphoenolpyruvate carboxykinase (PEPCK) is a ubiquitous enzyme found in all known groups of organisms, acting in the reversible conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP) in the presence of divalent metal ion, and dependent of adenosine 5’-triphosphate (ATP) or guanosine-5’-triphosphate (GTP). PEPCK is an important enzyme in the meta

2. POTENCIAIS ALVOS MOLECULARES PARA O DESENVOLVIMENTO DE NOVOS FÁRMACOS ANTITUBERCULOSE
Tuberculosis (TB) is an infectious disease caused by mycobacteria from the Mycobacterium genus, mainly by Mycobacterium tuberculosis (MTB). The World Health Organization (WHO) aims to reduce the number of TB cases worldwide in the coming years. Nevertheless, the increasing number of multidrug-resistant (MDR-TB) and extensive-drug resistance (XDR-TB) strains,

3. Achievement of constitutive fluorescent pLEXSY-egfp Leishmania braziliensis and its application as an alternative method for drug screening in vitro
BACKGROUND Gene reporter-fluorescent cells have emerged as alternative method for drug screening. OBJECTIVE Achievement of constitutive expression of fluorescent protein GFP by Leishmania braziliensis as alternative method for drug screening. METHODS L. braziliensis-GFP was generated using Leishmania tarentolae pLEXSY-egfp for constitutive expression of

4. ADME studies and preliminary safety pharmacology of LDT5, a lead compound for the treatment of benign prostatic hyperplasia
This study aimed to estimate the absorption, distribution, metabolism and excretion (ADME) properties and safety of LDT5, a lead compound for oral treatment of benign prostatic hyperplasia that has previously been characterized as a multi-target antagonist of α1A-, α1D-adrenoceptors and 5-HT1A receptors. The preclinical characterization of this compound co

5. Successful application of virtual screening and molecular dynamics simulations against antimalarial molecular targets
The main challenge in the control of malaria has been the emergence of drug-resistant parasites. The presence of drug-resistant Plasmodium sp. has raised the need for new antimalarial drugs. Molecular modelling techniques have been used as tools to develop new drugs. In this study, we employed virtual screening of a pyrazol derivative (Tx001) against four ma

6. Non-clinical studies required for new drug development - Part I: early in silico and in vitro studies, new target discovery and validation, proof of principles and robustness of animal studies
This review presents a historical overview of drug discovery and the non-clinical stages of the drug development process, from initial target identification and validation, through in silico assays and high throughput screening (HTS), identification of leader molecules and their optimization, the selection of a candidate substance for clinical development, a

7. Drug discovery for Chagas disease should consider Trypanosoma cruzi strain diversity
This opinion piece presents an approach to standardisation of an important aspect of Chagas disease drug discovery and development: selecting Trypanosoma cruzi strains for in vitro screening. We discuss the rationale for strain selection representing T. cruzi diversity and provide recommendations on the preferred parasite stage for drug discovery, T. cruzi d

8. Etiological diagnosis reduces the use of antibiotics in infants with bronchiolitis
OBJECTIVE: Acute bronchiolitis is a leading cause of infant hospitalization and is most commonly caused by respiratory syncytial virus. Etiological tests are not required for its diagnosis, but the influence of viral screening on the therapeutic approach for acute bronchiolitis remains unclear. METHODS: A historical cohort was performed to assess the impact

9. Atividade anticâncer de quercetina, narigina, morina e acetoxi DMU no tratamentos terapêutico de ratos inoculados com carcinossarcoma de Walker 256 / Anticancer activity of quercetin, naringenin, and morin Acetoxy DMU in the therapeutic treatment of rats inoculated with Walker 256 carcinosarcoma
Atualmente o câncer é um problema de saúde pública mundial, em virtude do aumento de sua incidência. A anorexia e a perda de peso involuntária são comuns em pacientes oncológicos. Esta condição, também conhecida como caquexia, afeta a capacidade funcional, a resposta ao tratamento, a qualidade de vida e a sobrevida do paciente. Estima-se que aprox

10. Epidemiology of hepatitis B virus infection in first-time blood donors in the southwestern region of Goiás, central Brazil
INTRODUCTION: Little is known about the epidemiology of hepatitis B virus (HBV) infection in populations from inner cities, especially in Central Brazil. Thus the objective of this study was to estimate the prevalence of HBV infection, and to analyze the factors associated with HBV infection, in a population of first-time blood donors in the southwestern reg

11. Associação do quimioterápico daunorrubicina a uma nanoemulsão rica em colesterol: estudos de regressão tumoral e farmacocinética / Association of the chemotherapeutic agent daunorubicin a cholesterol-rich nanoemulsion: regression studies pharmacokinetics and tumor
A nanoemulsão lipídica (LDE) se concentra nas células neoplásicas e pode ser utilizada como transportador de derivado lipofílico da daunorrubicina, como o Noleil- daunorrubicina (oDNR). Neste estudo, a LDE-oDNR foi preparada por homogeneização em alta pressão e sua toxicidade e atividade anti-tumoral testadas. A associação LDE-oDNR teve rendimento
