Synthesis, leishmanicidal activity, structural descriptors and structure-activity relationship of quinoline derivatives.

???displayArticle.abstract???
AIM: Considering the epidemiology of leishmaniasis, the emergence of resistant parasites to the approved drugs, and severe clinical manifestations, the development of novel leishmanicidal molecules has become of considerable importance. RESULTS: In this work, three commercially available and 19 synthesized quinoline derivatives were evaluated against promastigote and amastigote forms of Leishmania (Leishmania) amazonensis. In addition, structural parameters and molecular electrostatic potentials were obtained by theoretical calculations, allowing statistical (principal component analyses and hierarchical cluster analyses) and comparative (molecular electrostatic potentials vs leishmanicidal activities) studies, respectively. CONCLUSION: Principal component analyses and hierarchical cluster analyses suggested volume and polar surface area as possible structural descriptors for the leishmanicidal activity. Furthermore, a comparison between molecular electrostatic potentials and leishmanicidal activities afforded a reasonable structure-activity relationship.
