Analogs of benzoquinone-containing ansamycins for the treatment of cancer

摘要

The present invention provides analogs of benzoquinone-containing ansamycins and uses thereof for treating and modulating disorders associated with hyperproliferation, such as cancer ( formula (I) and (IV). The present invention provides analogs of benzoquinone-containing ansamycins where the benzoquinone is reduced to a hydroquinone and trapped by reaction with a suitable acid, preferably ones that increase the solubility and air stability of the resulting (17)-­ammonium hydroquinone ansamycin analog.
