WNT-5A, a secretory glycoprotein, is related to the proliferation of dermal papilla cells. To develop a hair-growth stimulant, we have been searching for inhibitors of WNT-5A expression. We identified radicicol (1) as an active compound, and synthesized several radicicol derivatives. Among them, 6,7-dihydro-10alpha-hydroxy radicicol (31) was found to function as a new potent WNT-5A expression inhibitor with relatively low toxicity and excellent stability.
WNT-5A是一种分泌性糖蛋白，与毛乳头细胞的增殖有关。为开发一种毛发生长刺激剂，我们一直在寻找WNT-5A表达的抑制剂。我们鉴定出萝卜素（1）为活性化合物，并合成了几种萝卜素衍生物。其中，6,7-二氢-10α-羟基萝卜素（31）被发现是一种新的强效WNT-5A表达抑制剂，具有相对较低的毒性和出色的稳定性。
