Synthesis of a number of derivatives of bisquinolines (3-9) have been reported here. Effect of these compounds on in vitro methemoglobin formation and methemoglobin reductase activity has resulted in the identification of two potential compounds (5 & 7), showing negligible methemoglobin toxicity.

berghei in vivo. These bisquinolines had IC50 values from 1 to 100 nM against P. falciparum in vitro. Six of the 11 bisquinolines were significantly more potent against the chloroquine-resistant W2 clone compared to the chloroquine-sensitive D6 clone. For bisquinolines 1-11 there was no relationship between the length of the bisquinoline heteroalkane bridge and antimalarial activity and no correlation
