摘要:
The natural product liphagal has been shown to function as a reasonably potent and selective inhibitor of the key signaling enzyme PI-3K alpha. We have been interested in developing an analog class of PI-3K inhibitors based upon this unusual terpenoid natural product. Toward that end, we have evaluated the binding of the natural product to its target protein computationally and formulated a class of simplified analogs based on the structural analysis. Utilizing the cycloadduct derived from tetrabromocyclopropene and furan, we were able to generate a key, versatile scaffold upon which to pursue this analog design. (C) 2010 Elsevier Ltd.
