title: SAR studies on azasterols as potential anti-trypanosomal and anti-leishmanial agents.
abstract: There is an urgent need for the development of new drugs for the treatment of neglected tropical diseases such as human African trypanosomiasis, Chagas disease and leishmaniasis. Azasterols, have been shown to have activity against the parasites which cause these diseases. In this paper we report synthesis of new azasterols and subsequent analysis of the SAR. The chemistry focused on variations in the ester at the 3beta-position of the sterol and the position of the nitrogen in the side chain. The data allowed us to derive preliminary pharmacophore models for the activity of the azasterols against the parasites which cause these diseases.
