Anti-infectives from mangrove endophytic fungi

Abstract Endophytic fungi reside within the plant tissues and maintain a strong symbiotic relationship. They are of utmost importance as promising sources of chemically diverse bioactive natural products. These microbes alter gene expression levels, modulate biosynthetic pathways, mitigate stressful conditions in plants and thereby play an important role in establishing plant's defence system against potential pathogens. The quest for discovering new chemical entities of pharmaceutical importance has drawn attention towards the mangrove ecosystem, which offers unique biodiversity. Mangroove associated fungi live under stress conditions and are the potential source of chemically diverse metabolites. Some fungal metabolites served as lead molecules for the development of new anti-infective agents. These fungi were modified/tailored using epigenetic means or culture optimization methods to improve the yield of useful metabolites. The present review describes the compounds isolated from mangrove endophytic fungi during 2013–2019 (up to June 2019) with focus on their chemical structure and their anti-infective activity. The compounds identified from endophytic fungi are arranged based on their antibacterial, antimycobacterial, antifungal, and antiviral activities.
