Synthesis of fluorescent derivatives of wortmannin and demethoxyviridin as probes for phosphatidylinositol 3-kinase

Bioorg Med Chem Lett. 2006 May 1;16(9):2518-21. doi: 10.1016/j.bmcl.2006.01.091. Epub 2006 Feb 7.

Abstract

Fluorescent analogs were synthesized of the potent PI 3-kinase inhibitors, wortmannin and demethoxyviridin. The esterification of 11-deacetylwortmannin, 17-hydroxywortmannin, and demethoxyviridin with the fluorescent carboxylic acids NBD-sarcosine and 7-dimethylaminocoumarin-4-acetic acid generated six novel fluorescent esters. Potent inhibition of PI 3-kinase-alpha was observed for the derivatives of 11-desacetylwortmannin and demethoxyviridin.
