SAR Analysis of Heterocyclic Compounds with Monocyclic and Bicyclic Structures as Antifungal Agents.

Infections caused by eukaryotic organisms, such as fungi, are generally more difficult to treat than bacterial infections. With the widespread use of antifungal drugs in humans and plants, resistance and toxicity have emerged. Therefore, it is desirable to develop new antifungal drugs with low toxicity that are not susceptible to the development of resistance. This review presents a summary of the past few years (2017-2021) of research on heterocyclic compounds as antifungal agents for use in humans and plants, focusing on the structure-activity relationships (SAR) of these compounds. This review may provide ideas and information for designing and developing new antifungal drugs with fewer side effects compared with currently available drugs.
