Therapeutic Potential of Secondary Metabolites from Endophytic Fungi in Biotechnology and Medicine

Endophytic fungi, which reside within plant tissues without causing harm, have attracted considerable scientific attention due to their wide-ranging applications. This review delves examines key aspects of research on endophytic fungi, focusing on isolation methods, the production of natural compounds, sampling strategies, and their therapeutic potential. Techniques such as surface sterilization and the use of selective media have revealed a vast diversity of fungi within plant hosts, shedding light on their ecological roles and biotechnological importance. Endophytic fungi are known to produce a variety of natural compounds, particularly secondary metabolites with medicinal properties. Prominent examples include taxol from Taxus endophytes and camptothecin from Camptotheca acuminata endophytes, both recognized for their anticancer activities. Various sampling strategies, from random collection to host-specific approaches, are essential for uncovering the diversity of these fungi. Additionally, optimization techniques for cultivation and extraction have been developed to maximize the yield of bioactive compounds and ensure sustainable production. Beyond anticancer agents, endophytic fungi have shown potential as sources of antimicrobials, antioxidants, and immunomodulators. These bioactive metabolites offer promising alternatives for drug development, particularly in response to the growing challenge of antibiotic resistance. This review contributes to the growing body of knowledge in the understanding of endophytic fungi and their applications across medicine, agriculture, and biotechnology.
