In order to meet the urgent need for novel antifungal agents with improved activity and broader spectrum, a series
of 3/4-[[N-alkyl-2-(2,4-difluorophenyl)-2-hydroxy-3-(1H-1, 2, 4-triazole)] propylamino] benzylethyl carbonate were
designed, synthesized and evaluated as antifungal agents. The MIC80 values indicate that all the compounds showed only
moderate or even no antifungal activities against nearly all the tested fungal pathogens. Moreover, the interactions of the
most active compounds in the drug binding site of CACYP51 were also explored with the help of docking studies.
Disclosed is a novel carbapenem derivative having a substituted imidazo[5,1-b]thiazole group at the 2-position on the, carbapenem ring have high anti-microbial activities against &bgr;-lactamase producing bacteria, MRSA, resistant-
Pseudomonas aeruginosa
, PRSP, enterococci, and influenza, and high stabilities to DHP-1. According to the present invention, there is provided a compound represented by the formula (I), or a pharmacologically acceptable salt thereof or an ester at the 3-position on the carbapenem ring thereof:

Abstract Highly regiospecific ortho–nitration of electronically diverse phenols is accomplished using Fe(NO3)3.9H2O for electron–rich and Cu(NO3)2.6H2O for electron–deficient phenols as the cheap nitrating agents. The reaction is carried out in CH3CN at 90 °C under mild and neutral conditions where structurally diverse phenols afford exclusively ortho–nitration products in moderate to good yields with
摘要 使用 Fe(NO 3 ) 3 .9H 2 O 富电子酚和 Cu(NO 3 ) 2 .6H 2 O 缺电子酚作为廉价的硝化剂,实现电子多样性酚类的高度区域特异性邻位硝化。该反应在 CH 3 CN 中于 90 °C 在温和和中性的条件下进行,其中结构多样的酚类以中等到良好的收率专门提供邻硝化产物,并且具有出色的官能团耐受性。通过实现生物活性化合物硝苯腈,建立了该策略的合成应用。
