A series of 8-quinolinethiolates, and 3-methyl-, 4-methyl-, 5-methyl-, 6-methyl-, 7-methyl-, and 6-methoxy-8-quinolinethiolates of tin(II), vanadium(IV), and molybdenum(VI) has been synthesized. Their cytotoxicity on HT-1080 tumor cells (human fibrosarcoma) and MG-22A (mouse hepatoma) cells has been studied. It was established that all of the investigated complexes of 8-quinolinethiol and majority of the complexes of 8-quinolinethiol derivatives possessed very high cytotoxicity towards both cell lines. Their toxicity in relation to mouse embryo fibroblasts NIH 3T3 depended on the position of the substituent in the quinoline ring. Complexes of tin and vanadium with 4-methyl-, 5-methyl-, and 6-methoxy-8-quinolinethiol derivatives were less toxic. 4-Methyl-, 5-methyl-, and 6-methoxy-8-quinolinethiolates of vanadium demonstrated the highest selectivity of cytotoxic action.
