[摘要]:WNT-5A is a secretory glycoprotein related to the proliferation of dermal papilla cells. While searching for an inhibitor of WNT-5A expression, a new compound, 13-bromomonocillin I (1), was isolated from the fermentation broth of the fungus Pochonia chlamydosporia, cultured in NaBr-supplernented medium. 13-Bromomonocillin I (1) exhibited WNT-5A expression inhibitory activity with an IC50 value of 0.25 mu M. |
