Synthesis and In Vitro Evaluation of Novel 1, 2, 4-Triazole Derivatives as Antifungal Agents

Abstract

Despite the advances in medicine and the emergence of new antifungal agents, fungal infections remain a significant cause of morbidity and mortality. Azoles are widely used as antifungal agents. Azoles interfere with the conversion of lanosterol to ergosterol by inhibiting a fungal cytochrome P450enzyme, lanosterol 14α-demethylase. Resistance to azoles, particularly fluconazole, is emerging to Candida albicans, after long-term suppressive therapy. Thus, there is an urgent need for newer potent antifungals to combat resistance developed against widely used azoles. In present work, we report synthesis of novel triazole derivatives of 7-hydroxy-4-methylcoumarin using various substituted aromatic aldehydes and evaluated for their in vitro fungicidal activity against Candida albicans at various concentrations to obtain minimum inhibitory concentration (MIC).
