Metal complexes of 5-carboxy-2-thiouracil with Mn(ll), Co(ll), Ni(ll), Cu(ll), Zn(ll) and Cd(ll) ions were synthesized, characterized, and subjected to a screening system for evaluation of antitumour activity against Sarcoma-180 (S-180) tumour cells. The complexes were characterized by elemental analysis, infrared

Die Pharmazie, 37(5), 355-356 (1982-05-01)
On reacting pyrimidine metabolites containing a carboxyl or sulfhydryl group with methylhydrazine or N-benzyl-N'-methylhydrazine, various methylhydrazonium salts of these metabolites were synthetized, e.g., the salts of 5-fluororotic acid, 5-azaorotic acid, 2-thiouracil-5-carboxylic acid and 2-thio-6-azathymine. Some of these salts exhibited a
