Endophytic Fungi-Alternative Sources of Cytotoxic Compounds: A Review

Area of Science:

• Mycology
• Pharmacology
• Biotechnology

Background:

• Cancer remains a leading global cause of mortality, driving the urgent need for novel chemotherapeutics.
• Natural products, particularly from endophytic fungi, offer diverse structural classes with unique anticancer bioactivities.
• Existing anticancer drugs like taxol and vinca alkaloids highlight the therapeutic potential derived from microbial sources.

Purpose of the Study:

• To review clinically used anticancer drugs derived from endophytic fungi.
• To explore novel endophytic fungal metabolites with cytotoxic potential against various cancer cell lines.
• To summarize strategies for improving fungal strain yields and metabolite production.

Main Methods:

• Literature review of established anticancer drugs (taxol, podophyllotoxin, camptothecin, vinca alkaloids).
• Analysis of recent research on endophytic fungal metabolites from terrestrial, mangrove, and marine environments.
• Compilation of data on mechanisms of action, isolation, characterization, and yield optimization.

Main Results:

• Endophytic fungi are a rich source of diverse anticancer compounds.
• Several clinically significant drugs have origins or analogs from endophytic fungi.
• Numerous novel cytotoxic metabolites from various fungal sources show promise against specific cancer cell lines.

Conclusions:

• Endophytic fungi represent a valuable and largely untapped reservoir for discovering new anticancer agents.
• Further research into fungal strain improvement and metabolite characterization can accelerate the development of novel cancer therapies.
• Exploring diverse ecological niches, including marine and mangrove environments, expands the potential for identifying unique bioactive compounds.
