Docosahexaenoic acid is potent against the growth of mature stages of Plasmodium falciparum; inhibition of hematin polymerization a possible target.

The present study investigates the potential effect of externally added unsaturated fatty acids on P. falciparum growth. Our results indicate that polyunsaturated fatty acids (PUFAs) inhibit the growth of Plasmodium in proportional to their degree of unsaturation.

Synthesis of thiazolyl hydrazonothiazolamines and 1,3,4-thiadiazinyl hydrazonothiazolamines as a class of antimalarial agents.

Novel thiazolyl hydrazonothiazolamines and 1,3,4-thiadiazinyl hydrazonothiazolamines were synthesized by a facile one-pot multicomponent approach by the reaction of 2-amino-4-methyl-5-acetylthiazole, thiosemicarbazide or thiocarbohydrazide and phenacyl bromides or 3-(2-bromoacetyl)-2H-chromen-2-ones in acetic acid with good to excellent yields. These new compounds were screened in vitro for their antimalarial activity; among them, four compounds, 4h, 4i, 4k, 4l, showed moderate activity with half-maximal inhibitory concentration (IC ) values of 3.2, 2.
