—— | 4-(2'-methyl-thiothiazol-4'-yl)pyridine | 80947-90-6 | C9H8N2S2 | 208.308 |
Syntheses are described for several 4-(1',2',4'-triazol-3'yl)pyridines, 3-and 4-(1',3',4'-thiadiazol-2'-yl)-pyridines, 3- and 4-(1',3',4'-oxadiazol-2'-yl)pyridines, 5-(1',3',4'-thiadiazol-2'-yl)pyrimidines and 5-(1',3',4'-oxadiazol-2'-yl)pyrimidines, all provided with a β-dimethylaminoethylthio side chain at the 5-position of the five-membered ring. The activities of these compounds as amplifiers of phleomycin-G against an in vitro culture of Escherichia coli B are tabulated and discussed.
Syntheses are described for 4-(thiazol-4'-yl)pyridines, each 2'-substituted by a dialkylaminoalkyl, dialkylaminoalkylthio or dialkylaminoalkylamino side chain; for 2- and 3-(thiazol-4'-yl)pyridines with a 2'-dimethylaminoethylthio substituent; for 4-(thiazol-2'-yl)pyridines with either a 4'- or a 5'-dialkylaminoalkylcarbamoyl substituent; and for some analogous compounds. The above and similarly substituted 2,4'-, 4,5'- and 5,5'-bipyrimidines have been screened for activity as amplifiers of phleomycin-G against Escherichia coli B by an improved in vitro procedure. The results are tabulated and discussed.
