Synthesis and antifungal activity of novel (1-aryl-2-heterocyclyl)ethylideneaminooxymethyl-substituted dioxolanes
摘要:
A novel series of (1-aryl-2-heterocyclyl)ethylideneaminooxymethyl-substituted dioxolanes IIIa-n were synthesized by condensation of substituted 1,3-dioxolan-4-ylmethyl p-toluenesulfonates 4 with 1-(hydroxyimino)-1-aryl-2-heterocyclylethanes 5. Compounds IIIa-n were found to have effective in vitro antifungal activity when evaluated against the pathogenic fungi Candida albicans, Aspergillus flavus and Fusarium solani with MIC (minimum inhibitory concentration) values of 10 mu g . ml(-1) for IIIa-l and 5 mu g . ml(-1) for IIIm,n.
The present invention relates to compounds of formula I
and pharmaceutically acceptable salts. These compounds can act as potential MEK inhibitors in the treatment of hyperproliferative diseases, like cancer and inflammation. The present invention also reveals methods of preparation thereof.
