- ItemOpen AccessAntimalarial and cysteine protease inhibitor pharmacophores as scaffolds for new antimalarial agents(2005) Musonda, Chitalu Christopher; Chibale, KellyThe work in this thesis is threefold: (i) A new series of antiplasmodial agents were initially designed based on the β-amino alcohol bioactiphore, a subunit that is found in a number of antimalarial agents. (ii) Various thiosemicarbozones and semicarbozones were designed and synthesized as potential mechanism-based inhibiotrs of parasitic cysteine proteases. (iii) Multicomponenet reactions offer the advantage of introducing chemical diversity in fewer steps than conventional multi step organic synthesis. New chloroquine-type compounds were designed and synthesized using the Ugi 4 component condensation reaction and its variants. The synthesized compounds ranged from simple peptidic molecules to rigid heterocycles.
