Endophytic Fungi and the Health Benefits from Their Potential Bioactive Secondary Metabolites

Endophytic fungi colonize the inner parts of the plant tissues asymptomatically. Numerous research studies have demonstrated that endophytes directly generate bioactive compounds, improving their host plants’ fitness. There has been a notable trend towards eco-friendly products in healthcare, medicine, and many other significant explorations of endophytic fungi, which have been discovered to generate diverse secondary metabolites with various biological properties, which has been a particular area of interest in this transformation. These fungi are an abundant source of secondary metabolites with functional properties, such as steroids, phenols, phenolic acids, quinines, phenolic, indole derivatives, amines, iso-coumarin derivatives, alkaloids, sesquiterpenes, flavonoids, diterpenes, lignans, terpenoids, peptides, chlorinated metabolites, and aliphatic compounds. New antibiotics, antimycotics, immunosuppressants, anticancer chemicals, and other bioactive secondary metabolites with diverse biological activity are now known to come from an endophytic fungus. Bioactive secondary metabolites produced by endophytic fungal organisms have been found to have unexpected medicinal promise. Additionally, it adds to the pharmaceutical and probiotic health products we regularly use to balance out diets that can improve health conditions. It also can enhance health conditions. The focus of the current study and emphasis is placed on endophytic fungi’s significance in acquiring contemporary bioactive compounds that exhibit a variety of biological traits, including the potential to be antiparasitic, anti-pathogenic, antibacterial, antitumor, antioxidant, immunoregulatory, neuroprotective, and cytotoxic to cancer cells. Endophytes are an endless source of pharmacologically significant substances. Considerable attention is dedicated to studies that seek to elucidate the mechanism through which these metabolites exert health benefits.
