Synthesis and evaluation of novel antifungal agents-quinoline and pyridine amide derivatives
摘要:
Quinoline amide, azaindole amide and pyridine amides were synthesized and tested for in vitro antifungal activity against fungi. These synthesized amides have potent antifungal activity against Candida albicans and Aspergillus fumigatus. Our results suggest that hetero ring amides may be potent antifungal agents that operate by inhibiting the function of Gwt1 protein in the GPI biosynthetic pathway. (C) 2010 Elsevier Ltd.

The present invention provides an antifungal agent represented by the formula:
[wherein A
1
represents a 3-pyridyl group which may have a substituent, a quinolyl group which may have a substituent, or the like; X
1
represents a group represented by the formula —NH—C(═O)—, a group represented by the formula —C(═O)—NH—, or the like; E represents a furyl group, a thienyl group, a pyrrolyl group, a phenyl group, a pyridyl group, a tetrazolyl group, a thiazolyl group or a pyrazolyl group; with the proviso that A
1
may have 1 to 3 substituents, and E has one or two substituents].
