Estrutura eletrônica de materiais orgânicos: moléculas antimalariais de sulfonamidas e anilinoquinolinas

Abstract

Neste trabalho estudamos dois grupos de moléculas: as anilinoquinolinas e as sulfonamidas, inibidores do Plasmodium causador da malária, com o objetivo de correlacionar a estrutura eletrônica com a atividade antimalarial. Em nossas buscas utilizamos métodos empíricos e semi-empíricos para o estudo conformacional e obtenção dos descritores eletrônicos. Também aplicamos vários métodos estatísticos como: Regressão Linear Simples e Múltipla, Análise de Componentes Principais (PCA) e Análise Discriminante Linear (LDA), para verificar uma possível correlação estrutura-atividade dessas moléculas. Os resultados apontaram os descritores eletrônicos mais relevantes na classificação das moléculas antimalariais.

In this work we study two groups of antimalarial compounds: the anilinoquinolines and sulfonamides, aiming the correlation of the electronic structure with the antimalarial activity. In our studies we employ empirical and semi empirical quantum chemistry methods for the geometry optimization and calculation of the electronic descriptors. Also we employed the statistical methods Simple and Multiple Linear Regression, Principal Component Analysis (PCA) and Linear Discriminating Analysis (LDA), to verify the existence of a possible structure-activity correlation for these compounds. The results of this work have pointed out the best electronic descriptors in the classification of the active compounds.
