These data suggest the presence of diastereoisomers, except for the complex with glycine, amino acid that does not exhibit chiral carbon. The compounds are active against the MDA-MB-231 tumor cells and against Mycobacterium tuberculosis. The cationic ruthenium complexes with amino acids, reported here, show similar cytotoxicity against the MDA-MB-231 tumor cells. When compared with analogs complexes containing 2,2′-bipyridine as ligands, instead of 1,10-phenatroline, the new complexes studied here are, in general, roughly twice more active than the 2,2′-bipyridine ones and their IC50 values comparable with the cisplatin. In addition, low MICs values were obtained against Mycobacterium tuberculosis compared with the reference drugs, cycloserine and ethambutol.
