چکیده

Neste artigo mostramos um procedimento desenvolvido em nossos laboratórios que identifica “novos” compostos biologicamente ativos distintos de compostos previamente conhecidos no que diz respeito à especificidade da ação e outras características. O procedimento envolve o mapeamento de uma série de compostos ativos (série de treinamento), através de interações lipofílicas e de ligações hidrogênio com o sítio de uma enzima ativa. As interações identificadas e mapeadas são, então, removidas (com exceção daqueles sítios de interação criticamente importantes) e, apenas as interações não utilizadas pelos compostos ativos são mantidas. Os modelos farmacofóricos são gerados e escalonados para os sítios previamente enumerados. Esse modelo é então usado para varreduras de bancos de dados tridimensionais e identificação de novas substâncias matrizes. Este procedimento foi aplicado para inibidores da protease do vírus HIV-1. Vários compostos com atividade moderada na ordem de “micro”(letra mi)Molar foram selecionados pelo modelo farmacofórico proposto.

Discovery of Novel Glucagon Receptor Antagonists Using Combined Pharmacophore Modeling and Docking

Glucagon and the glucagon receptor are most important molecules control over blood glucose concentrations. These two molecules are very important to studies of type 2 diabetic patients. In literature, several classes of small molecule antagonists of the human glucagon receptor have been reported. Glucagon receptor antagonist could decrease hepatic glucose output and improve glucose control in d...

Discovery of Human HMG-Coa Reductase Inhibitors Using Structure-Based Pharmacophore Modeling Combined with Molecular Dynamics Simulation Methodologies

3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) catalyzes the conversion of HMG-CoA to mevalonate using NADPH and the enzyme is involved in rate-controlling step of mevalonate. Inhibition of HMGR is considered as effective way to lower cholesterol levels so it is drug target to treat hypercholesterolemia, major risk factor of cardiovascular disease. To discover novel HMGR inhibitor, we p...

Reviewing Ligand-Based Rational Drug Design: The Search for an ATP Synthase Inhibitor

Following major advances in the field of medicinal chemistry, novel drugs can now be designed systematically, instead of relying on old trial and error approaches. Current drug design strategies can be classified as being either ligand- or structure-based depending on the design process. In this paper, by describing the search for an ATP synthase inhibitor, we review two frequently used approac...

Ligand and structure based pharmacophore modeling to facilitate novel histone deacetylase 8 inhibitor design.

Over expression of histone deacetylases (HDACs) leads to the suppression of various gene expressions including cancer suppressor gene. Thus, novel inhibitors of these enzymes can be a valid method to treat cancers. To facilitate the discovery of novel HDAC8 inhibitors, pharmacophore models were generated using ligand and receptor based approaches and validated with a database of active and inac...
