In vitro antiplasmodium and antitrypanosomal activities, β-haematin formation inhibition, molecular docking and DFT computational studies of quinoline-urea-benzothiazole hybrids.

ABSTRACT: Quinoline-urea-benzothiazole hybrids exhibited low to sub-micromolar in vitro activities against the Plasmodium falciparum (P. falciparum) 3D7 chloroquine (CQ)-sensitive strain, with compounds 5a, 5b and 5f showing activities ranging from 0.33 to 0.97 μM. Against the formation of β-haematin, the majority of the tested compounds were comparable to the reference drug, chloroquine (CQ), with compounds 5c (IC₅₀ = 9.55 ± 0.62 μM) and 5h (IC₅₀ = 9.73 ± 1.38 μM), exhibiting slightly better in vitro efficacy than CQ. The hybrids also exhibited low micromolar to submicromolar activities against Trypanosoma brucei brucei, with 5j-5k being comparable to the reference drug, pentamidine. Compound <
