简介内容:VDR agonist 1 (compound 28), a nonsteroidal Vitamin D receptor (VDR) agonist, demonstrates potent activity with a low IC 50 of 690 nM in MCF-7 cells. It inhibits cell cycle progression through upregulation of p21 and p27, and induces apoptosis by elevating BAX expression while reducing Bcl-2 levels [1].
