产品描述:
ZK 159222 is an antagonist of the vitamin D receptor (VDR).{52664,52665} It stabilizes the VDR in an antagonistic conformation that prevents interaction with coactivator proteins.{52666} ZK 159222 inhibits VDR-mediated target gene activation when used at concentrations of 300 and 1,000 nM in reporter assays. Preincubation of preadipocytes with ZK 159222 (0.01 and 1 µM) decreases the secretion of IL-1β, IL-6, IL-8, CCL2, and RANTES induced by macrophage-conditioned medium (MacCM).{52667} It also decreases the secretion of these cytokines in preadipocytes prestimulated with MacCM and decreases MacCM-induced phosphorylation of p44/42 and p38 MAPK in preadipocytes.
