Stereoselective Synthesis and in Vitro Antifungal Evaluation of (E)- and (Z)-Imidazolylchromanone Oxime Ethers
摘要:
A series of (E)- and (Z)-2,3-dihydro-3-(1 H-imidazol-1 -yl)-4H-1 -benzopyran-4-one oxime ethers have been synthesized and tested for antifungal activity Most compounds showed moderate to potent in vitro antifungal activity. Among the tested compounds, compound (E)-3 d was the most active agent against Candida albicans and Aspergillus niger, and compounds (Z)-(3 a) and (E)-3 a were the most potent compounds against Microsporum gypseum. Detailed stereoselective synthesis, spectroscopic, and biological data are reported.

A series of azolylchroman derivatives were prepared as conformationally constrained analogs of (arylalkyl)azole anticonvulsants. The anticonvulsant activities of the compounds were evaluated by determining seizure latency and protective effect against pentylenetetrazole (PTZ)-induced lethal convulsions in mice at a dose of 5 mg/kg. Among these compounds, 7-chloro-3-(1H-imidazol-1-yl)chroman-4-one and 3-(1H-1.2,4-triazol-1-yl)chroman-4-one exhibited significant action in delaying seizures as well as effective protection against PTZ-induced seizures and deaths.
