Derivatives of 2-aryl-substitute (o-hydroxy-, m-bromo-, o-methoxy-, o-nitro-phenyl or 4-pyridyl) benzothiazole were synthesized and tested for their mutagenicity in in vitro assays: (i) in the Ames test with Salmonella typhimurium TA98 and TA100 strains; and (ii) in the sister chromatid exchange (SCE) in cultured human lymphocytes. The four of compounds (BT-11, B-12, BT-14 and BT-15) caused statistically significant increase in revertant colonies of TA98 and TA100. Treatment of lymphocytes with compounds also caused a significant increase in SCE/cell in association with high levels and long exposure (300 mu g/mL and 48 h) of the four compounds. It can be concluded that benzothiazole derivatives showed mutagenic activity and were also able to exert a genotoxic effect reducing both the replication index and mitotic index.
