CYP19 (aromatase): Exploring the scaffold flexibility for novel selective inhibitors
摘要:
Several derivatives out of a series of antifungal agents exhibited a good inhibitory potency against aromatase as well as a fairly good selectivity toward CYP17, even if lacking H-bond accepting substituents. Their common structural feature is a flexible backbone that did not fit into previously reported CYP19 models. Thus, a ligand-based approach was exploited to develop a novel statistically robust, self-consistent and predictive 3D-QSAR model herein proposed as a helpful tool to design new aromatase inhibitors.

A New Class of Antifungal Agents. Synthesis and Antimycotic Activity of DisubstitutedN-Azolylamines
摘要:
In this study we extended our exploration of the N-azolylamine moiety for its antifungal activity. We prepared a number of N-azolylamino derivatives. The synthetic sequence includes the preparation of aminoazole Schiff bases, and the reduction and the alkylation of the corresponding secondary amines. The title compounds were evaluated in vitro against several pathogenic fungi responsible for human disease. The most potent antimicrobial compound was the N-(biphenyl-4-yl)methyl-N-(2,4-dichlorophenyl)methyl-1H-imidazol-1-ylamine (21), which was found to be active against yeasts and dermatophytes; its potency and selectivity were comparable to those of miconazole.
