Synthesis and Evaluation of Biological Activities of Aziridine Derivatives of Urea and Thiourea.
In the present paper, we report the synthesis and evaluation of in vitro antimicrobial activities of aziridine-thiourea derivatives. A series of aziridines in reaction with isocyanates and isothiocyanates to obtain urea and thiourea derivatives were used. The structures of all new products were confirmed based on spectroscopic data (¹H-NMR, 13C-NMR, HR-MS). These compounds were screened for the...
متن کاملSynthesis of novel urea and thiourea derivatives of diphenylphosphoramidate and their antimicrobial activity
A series of novel urea/thiourea derivatives of diphenylphosphoramidate have been synthesized in two steps. In the first step, 4-aminoaniline/4, 4’diaminodiphenylsulfone (Dapsone) was reacted with diphenyl chlorophosphate in the presence of triethylamine (TEA) to get intermediates. Intermediates further treated with various substituted aromatic isocyanates/ isothiocyanates in the presence of TEA...

متن کاملSynthesis and biological activity of substituted urea and thiourea derivatives containing 1,2,4-triazole moieties.
A series of novel thiourea and urea derivatives containing 1,2,4-triazole moieties were synthesized and evaluated for their antifungal and larvicidal activity. Triazole derivatives 3a-e and 4a-e were synthesized by reacting thiocarbohydrazide with thiourea and urea compounds 1a-e and 2a-e, respectively, in a 130-140 °C oil bath. The proposed structures of all the synthesized compounds were conf...
