Bis-alkylamineIndolo[3,2-b]quinolines as hemozoin ligands: implications for antimalarialcytostatic and cytocidal activities

To get insight into the relevance of targeting hemozoin (Hz) crystals, two isomeric series, N5,N10-bis-alkylamine (2a-k) and N10,O11-bis-alkylamine (3a-k) indolo[3,2-b]quinolines, were evaluated for their in vitro activity against chloroquine (CQ)-resistant and sensitive strains of Plasmodium falciparum.

Exploring the 3-piperidin-4-yl-1H-indole scaffold as a novel antimalarial chemotype

A series of 3-piperidin-4-yl-1H-indoles with building block diversity was synthesized based on a hit derived from an HTS whole-cell screen against Plasmodium falciparum. Thirty-eight compounds were obtained following a three-step synthetic approach and evaluated for anti-parasitic activity.
