Hydrazinehydrate reacts with warm ethanolic solutions of 1-aryl-4-methyl-4-isodithiobiurets to yield 3-amino-5-anilino-1,2,4-triazoles, but 2-ethyl-1-phenyl-2-isodithiobiuret afforded 3-anilino-5-mercapto-1,2,4-triazole.
Structure–activity relationship of dihydroimidazo-, dihydropyrimido, tetrahydrodiazepino-[2,1-b]-thiazoles, and -benzothiazoles as an acylation catalyst
synthesized by a condensation reaction of cyclic thioureas 15 and α-bromoacetophenones 14. Investigations of the acylation reactions of 1-phenylethanol with acid anhydrides in the presence of these cyclic isothiourea catalysts revealed their structure–activity relationships. Remarkable electronic effects resulting from substituent(s) on a benzo or phenyl moiety and the influence of the size of the annulating

A series of antitumoragents based on terminal functionalized dipeptide derivatives containing the thiourea moiety were synthesized and evaluated for antiproliferative activity using a panel of cancer cell lines, and the effects and mechanism of apoptosis induction were determined. These compounds exhibited significant selectivity to different cancer cell lines with IC50 values at micromolar concentrations
