title: Synthesis and mycobactericidal properties of metal complexes of isonicotinoyldithiocarbazic acid.
abstract: An isonicotinoyldithiocarbazic acid (IN-DtczH) ligand, synthesized from isoniazid, was complexed with transition metals and evaluated for anti-mycobacterial activity as well as toxicity towards human-transformed rhabdomyosarcoma (RD) cells in vitro. Complexes with Ni, Co and Zn showed MIC of 2, 2 and 50 mug/ml against Mycobacterium tuberculosis H(37)Rv, and 10, 100 and 50 mug/ml against a multidrug-resistant strain of M. tuberculosis. They had little cytotoxic effect on the RD cells. In contrast, the Cu complex was highly cytotoxic with a low anti-mycobacterial activity.
