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.

N10,N11-di-alkylamine indolo[3,2-b]quinolines as hemozoin inhibitors: design, synthesis and antiplasmodial activity

We recently reported that potent N10,O11-bis-alkylamine indolo[3,2-b]quinoline antimalarials act as hemozoin (Hz) growth inhibitors. To improve access and binding to the target we have now designed novel N10,N11-di-alkylamine bioisosteres.
