The synthesis, physicochemical characterization and in vitro antimalarial activity of a series of indolo[3,2-c]quinolines (9a-f) are described. There is only a poor correlation between the activity and hydrophobicity. In contrast, 33% of the observed

The antimalarial drug mefloquine binds avidly to phospholipids in biomembranes. The thermodynamics of the partitioning process in dimyristoylphosphatidylcholine (DMPC) bilayers was investigated to give some insight into the drug-phospholipid interact

The thermodynamics of the partitioning of 7-chloro-4-(4'-methoxy)anilinoquinoline (I) and its cyclized analogue, 3-chloro-8-methoxy-11H-indolo[3, 2-c]quinoline (II) have been determined in octanol-buffer and liposome systems.Under the conditions of p

A series of indolo[3,2-c]quinolines (1b–e) was synthesized by Fischer indolization of 7-chloro-1,2,3,4-tetrahydroquinolin-4-one with the appropriate hydrazines (7b–e). Evaluation of in vitro antimalarial activity was carried out against a chloroq

Alternative methods that can be used to synthesize certain key intermediary compounds in the preparation of 1 alpha-hydroxylated vitamin D have been described. These methods are simple and give higher yields than the reported procedures.

The change in hydrophobicity on N-oxidation of the ring nitrogen of quinoline and its 4-amino derivatives was determined by the shake-flask method and reverse phase liquid chromatography (RPLC), buffered at an appropriate pH. Hydrophobicity was expre

Mefloquine enantiomers (+) -1, (-) -1 were found to be stereospecific in their inhibition of acetylcholinesterase and butyrylcholinesterase, (-) -1 being the more potent inhibitor in both cases. Similar observations were also made with respect to (-)
