Abstract

A series of novel, substituted 2-chloro-3-[(thiazol-2-yl)amino]-1,4-naphthoquinones have been prepared and shown to exhibit promising concentration-dependent activity against human SH-SY5Y cells, Plasmodium falciparum, Mycobacterium tuberculosis and P. aeruginosa. Substituent effects on observed bioactivity have been explored; the para-fluorophenyl derivative 3d exhibited activity across the range of the bioassays employed, indicating the potential of the 2-chloro-3-[(4-arylthiazol-2-yl)amino]-1,4-naphthoquinone scaffold in the development of novel, broad spectrum therapeutics.
