Information AL082D06 AL082D06 is a nonsteroidal glucocorticoid receptor (GR) antagonist with no detectable binding affinity for the highly related receptors for mineralocorticoids, androgens, estrogens, and progestins. Targets Glucocorticoid receptor 210 nM(Ki) In vitro D06 can antagonize steroid-mediated induction of glutamine synthetase RNA in MG63 cells and TAT enzyme in human skin fibroblasts. It can act to inhibit both transcriptional activation and repression by receptor in a variety of cell types on a variety of genes. D06 partially blocks glucocorticoid receptor (GR) translocation to the nucleus, and completely blocks DNA binding by the receptor.
