Abstract: | The Discovery of Medicines from Plants: A Current Biological Perspective. The last 50 years have seen tremendous innovations in the process of discovering novel bioactive compounds from plants. Every stage of the natural products discovery and development pipeline has seen major advances, so as a result, today it is possible to evaluate large numbers of plant extracts efficiently and in more effective ways against a wider array of disease targets. Despite all of these technological advances and numerous large-scale discovery efforts, the number of new drugs developed as natural products from plants to reach the market has been surprisingly low, very different from the continuing productive discovery work from microbes. The innovations in the discovery process are reviewed, possible explanations for low success of recent discovery efforts are explored, and an effort is made to estimate the future potential of plants as a discovery resource. It may be that the low rate of discovery during this developmental period of natural products discovery is a consequence of technological limitations of the discovery process rather than a lack of interesting compounds in plants, and that even when necessary assumptions are taken into account, conservative estimates would indicate great potential for the discovery of new drugs from plants. |
