Because of what appears to be their contribution to the host plant, the endophytes may produce a plethora of substances of potential use to modern medicine. Strobel, G. and Daisy, B.

Bioprospecting for Microbial Endophytes and Their Natural Products
This is yet another example of an endophytic actinomycete having promising antibiotic properties. Thus, it behooves the investigator to carefully study and select the biological source before proceeding, rather than to have a totally random approach in the biological source material.
It appears that this loss of buoprospecting can be attributed to the enormous effort and expense that is required to pick and choose a theeir source and then to isolate active natural products, decipher their structures, and begin the long road to product development NRRLan endophyte of Grevillea pteridifolia.
This is witnessed by the discovery of a wide range of products and microorganisms that already hold an inkling for future prospects as mentioned in this report. The natural product often serves as a lead molecule whose activity can be enhanced by manipulation through combinatorial and synthetic chemistry.

This early work set the stage for a more comprehensive examination of the ability of other Taxus species and other plants endophyttes yield endophytes producing paclitaxel. These results may lead to new therapies for diabetes It was isolated as an endophyte from Tripterigeum wilfordiia medicinal plant native to Eurasia Thirty-four plants consisting of eight nqtural species were collected along the Oregon coast from four different sites. The volatile components of this organism are totally different from those of either M.
Furthermore, several other P. Bacterial endophytes have been shown to improve abiotic and biotic stress responses in plants.

Abstract Endophytic microorganisms are to be found in virtually every plant on earth. Each of the five classes of volatile compounds produced by the fungus had some inhibitory effect against the test fungi and bacteria, but none was lethal.
Muscodor albus micrboial a newly described endophytic fungus obtained from small limbs of Cinnamomum zeylanicum cinnamon tree Recent and future discoveries of pharmacologically active metabolites from tropical fungi, p. The presence of paclitaxel in yew species prompted the study of their endophytes.
The following section shows some examples of natural products obtained from endophytic microbes and their potential in the pharmaceutical and agrochemical arenas. This finding may have important implications in the biology of P. The program can recognize and eliminate from study common fungi producing known compounds and thereby direct attention to the evaluation of rare samples, which are more likely to produce microbiaal with novel bioactivity.
Ispoestacin, an isobenzofuranone from Pestalotiopsis microspora, possessing antifungal and antioxidant activities. One-hundred and thirty-three different bacterial isolates, ninety-four of which were unique, representing endophytez different taxonomic groups were found.

Consequently, the opportunity to find new and interesting endophytic microorganisms among myriads of plants in different settings and ecosystems is great. Recently, a complete synthesis of torreyanic acid has been successfully completed using the application of a biomimetic oxidation-dimerization cascade Butterworth-Heinemann, London, United Kingdom.
Now, more than 30 of these are on hand as endophytes, and many possess antibiotic activity U. This approach resulted in the discovery of the fungus Tolypocladium inflatumfrom which cyclosporine, a hugely beneficial immunosuppressant, was isolated 7.
Phomopsichalasin, a metabolite from an endophytic Phomopsis sp.
It is important to realize that the primary purpose of combinatorial chemistry should be to complement and assist the efforts of natural-product drug discovery and development, not to supersede it This is a concept that was originally proposed as a mechanism to explain why the endophytic fungus T. The need for new and useful compounds to provide assistance and relief in all aspects of the human condition is ever growing. Certainly, one of the major problems facing the future of endophyte biology and natural-product discovery is the rapid diminishment of rainforests, which hold the greatest possible resource for acquiring novel microorganisms and their products.
Furthermore, the logic and rationale for time and effort spent on drug discovery using a target site-directed approach have been overwhelming.
