Tsutsumi, Sadae published the artcileImprovement of antileprous drugs. III. Inhibitory effect of some drugs on the growth of leprosy bacilli in the footpads of mice, Synthetic Route of 4604-72-2, the publication is Repura (1970), 39(1), 33-47, database is CAplus.
The growth of leprosy bacilli in the footpads of mice was inhibited by cycloserine [68-41-7], rifampicin [13292-46-1] and 1-phenylthiocarbamoyl-2-phenylacetylene (I) [14901-33-8] when administered to mice at concentrations of 0.1 or 0.5 mg/g. About 60 compounds, including 4-aryl-1,2,4-triazoles, 3-aryl-2-thiohydantoins, and 1-arylthiocarbamoyl-2-phenylacetylenes, were newly synthesized to study their bactericidal activity.
Repura published new progress about 4604-72-2. 4604-72-2 belongs to pyrazines, auxiliary class Pyrazine,Amine,Amide, name is Pyrazine-2-carbothioamide, and the molecular formula is C18H24N6O6S4, Synthetic Route of 4604-72-2.
