Kakimoto, Shichiro published the artcileStructure and activity of carbothionamides, Computed Properties of 4604-72-2, the publication is Tuberkulose-Forschungsinstitut Borstel, Jahresbericht (1961), 240-81, database is CAplus.
Approx. 70 carbothionamides were tested for inhibition of growth of Mycobacterium. IR estimation of polarization of the C:S bond showed that increasing negativity correlated with antibacterial activity. Toxicity of compounds was due to H2S production in acid solution 95 references
