Structure-Based Optimization of Azole Antifungal Agents by CoMFA, CoMSIA, and Molecular Docking

Abstract: In a continuing effort to develop highly potent azole antifungal agents, the three-dimensional quantitative structure-activity relationship methods, CoMFA and CoMSIA, were applied using a set of novel azole antifungal compounds. The binding mode of the compounds at the active site of lanosterol 14alpha-demethylase was further explored using the flexible docking method. Various hydrophobic, van der Waals, pi-pi stacking, and hydrogen bonding interactions were observed between the azoles and the enzyme. Based on… Show more

“…In fact the importance of charge transfer between azole derivatives and the iron atom of lanosterol 14α-desmethylase active site heme portion has already been reported. [24][25][26][27] Taken together, this analysis suggests that the dipole moment (JGI4) and the presence of the C-O fragment at topological distance of 06 and 07, that relates to OH in the most active compounds, are important for the largest activity of these compounds.…”

“…On the basis of the three-dimensional model of lanosterol 14α-demethylase (CYP51) from C albicans constructed in previous studies [15][16][17][18] , a series of 2-aminotetralin compounds was designed and synthesized as antifungal agents. We hope that these compounds are able to interact with amino acid residues in the active site of CYP51 and avoid connection with the iron atom of heme, and therefore they can not only generate potent antifungal activity but attenuate severe toxicities of azoles.…”
