Natural Substances as Valuable Alternative for Improving Conventional Antifungal Chemotherapy: Lights and Shadows

Journal of Fungi, Journal Year: 2024, Volume and Issue: 10(5), P. 334 - 334

Published: May 5, 2024

Fungi are eukaryotic organisms with relatively few pathogenic members dangerous for humans, usually acting as opportunistic infections. In the last decades, several life-threatening fungal infections have risen mostly associated worldwide extension of chronic diseases and immunosuppression. The available antifungal therapies cannot combat this challenge because arsenal compounds is scarce displays low selective action, significant adverse effects, increasing resistance. A growing isolation outbreaks triggered by species formerly considered innocuous being recorded. From ancient times, natural substances harvested from plants been applied to folk medicine some them recently emerged promising antifungals. most used briefly revised herein. Combinations chemotherapeutic drugs products obtain more efficient gentle treatments also revised. Nevertheless, considerable research work still necessary before their clinical use can be generally accepted. Many a highly complex chemical composition, active principles partially unknown. Here, we survey field underlying lights shadows both groups.
