Fifty-two kinds of N′-phenylhydrazides were successfully designed and synthesized. Their antifungal activity in vitro against five strains C. albicans (Candida albicans) was evaluated. All prepared compounds showed varying degrees their MIC80 (the concentration tested when inhibition rate at 80%), TAI (total index), TSI susceptibility index) calculated. The inhibitory activities 27/52 fluconazole-resistant fungi 4395 5272 much better than those fluconazole. values 14/52 fungus 5122 less 4 μg/mL, so it the most sensitive (TSIB = 12.0). A11 best SC5314, 4395, (MIC80 1.9, 4.0, 3.7 μg/mL). B14 D5 four (2.71), (2.13), (2.25) are highest. Further exploration mechanisms revealed that treated with compound produced free radicals reactive oxygen species, mycelium morphology damaged. In conclusion, N′-phenylhydrazide scaffold potential development lead compounds. Among them, A11, B14, demonstrated particularly promising held as novel agents.

We have found a chameleonic reactivity of imidoyl sulfoxonium ylides. On the one hand, ylides react with electron-deficient reagents, such as alkynyl esters, to lead formation 1,2-dihydro-pyridines. The methyl group attached sulfur atom acts methylene donor. other pyridinium 1,4-zwitterionic thiolates, which leads functionalized pyrroles. Both transformations feature mild reaction conditions and good functional tolerance.
