Antimalarial benzo[c]phenanthridines

Bioorganic & Medicinal Chemistry Letters, 2005
Analogues of the antimalarial alkaloid nitidine have been prepared with high potency against both chloroquine-sensitive and -resistant strains of Plasmodium falciparum in vitro. Simple modifications, using an established synthetic route, resulted in an analogue with IC(50) below 5ng/mL against a chloroquine-sensitive strain of P. falciparum.

Acridities and phenanthridines

2020
The acridine and phenanthridine chromophores both contain a central six-membered aromatic nitrogen heterocycle, with benzo rings fused onto each side. Although sulfonated and hydroxylated acridines have been synthesized, none are used as stains. The hydrophilic/lipophilic properties of the dyes under usage conditions are varied.
