Fatty acids and their amide derivatives from endophytes: new therapeutic possibilities from a hidden source

Fatty acid and their amide derivatives are natural self-defense agents in plants. They have been observed to be broadly bioactive against a variety of disease agents. The mechanism of action understood so far being their targeting the protein synthesis and causing leakage of the intracellular components. Owing to their broad bioactivity, the fatty acids and their amides as therapeutics can cover a wide range of indications such as cancer, bacterial infections, parasitic infection, inflammations, diabetes and obesity to name a few. The microorganisms residing inside the healthy plant tissues are a unique niche for exploration of novel bioactive compounds. The recent identification of fatty acid amide derivatives as well as prior reports from endophytes have drawn fresh attention to this unique source for their isolation. Hence, they represent an exciting opportunity for the development of new therapeutic agents against existing disease causative agents. In this paper, we will discuss the production of fatty acids and amide derivatives by plants and their associated endophytes. Their reported bioactivities establishing their potential benefit as possible therapeutic agents will also be examined.
