Bonati, F. published the artcileAntibacterial activity of substituted thioamides in relation to chemical constitution, COA of Formula: C5H5N3S, the publication is International Congress of Chemotherapy, Proceedings (1964), 1963(1), 183-5, database is CAplus.
A large number of the title compounds were tested in vitro against Mycobacterium tuberculosis H37Rv, Staphylococcus aureus (Oxford strain), Escherichia coli (1st. Sieroterap. Milanese 95), Proteus vulgaris (I.S.M. 2), and Pseudomonas aeruginosa (I.S.M. 32). Structural formulas and inhibitory concentrations of the compounds are indicated for M. tuberculosis, S. aureus, and Ε. coli. For simple thioamides, inhibitory activity was almost absent for the 4 test organisms other than M. tuberculosis. The test compounds (Mannich bases) contained either 1 or 2 N atoms in their heterocyclic rings. The inhibitory concentrations for P. vulgaris and P. aeruginosa were very similar to those for Ε. coli. In antitubercular activity, the ethyl isonicotinic thioamide was superior to other thioamides, while the activity of Mannich bases derived from 3-pyridine thiocarboxamide and from pyrazinethiocarboxamide was superior to that of various other compounds
