Abstract

Substituted lawsone Mannich Bases 2a-e, 3a-e and 4a-e were prepared and tested for their biological activities. The new fatty alkyl substituted compounds 2a-c exhibited strong and selective growth inhibitory activities in the low one-digit micromolar and sub-micromolar range against a panel of human Cancer cell lines associated with ROS formation. In addition, compounds 2a-c revealed sub-micromolar anti-trypanosomal activities against parasitic Trypanosoma brucei brucei cells via deformation of the microtubule Cytoskeleton. The N-hexadecyl compound 2c was also highly active against locally isolated Entamoeba histolytica Parasite samples exceeding the activity of metronidazole.
