Entendendo o processo químico de bioativação da sinvastatina por métodos experimentais e computacionais: uma aula prática

Abstract

Cholesterol is a lipid which in high concentration can be an important risk factor for coronary diseases and atherosclerotic lesions. This lipid presents an endogenous biosynthesis that involves several steps; one of them is modulated by the enzyme 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase). HMG-CoA reductase is inhibited by statins, such as simvastatin, in order to reduce seric become active. The structure of simvastatin has a lactone ring that undergoes enzymatic hydrolysis giving the 3,5-dihydroxy-heptanoate metabolite. This group is essential for simvastatin antilipemic activity, but significantly increases their water solubility. Make students understand the influence of chemical groups and organic functions on physicochemical properties and pharmacokinetic profiles of drugs, as simvastatin, is not an easy task. In this context, combine practical strategies and theoretical presentations of the concepts involved on drug biotransformation certainly could improve the teaching learning process. This manuscript correlates organic strategies and in silico techniques throught simvastatin hydrolysis followed by comparative ClogP measurement. This approach intends to allow students to have contact with a cross-platform and multidisciplinary learning, making it ludic, easier and more interesting than theoretical classes.
