Product Description
Cell permeable, nonsteroidal glucocorticoid receptor modulator with high binding affinity. Exerts anti-inflammatory potential by down-modulating TNF-induced pro-inflammatory gene expression, such as IL-6 and E-selectin. Unlike dexamethasone (Prod. No. ALX-370-002) it does not enhance glucocorticoid response element (GRE)-driven gene expression or induce glucocorticoid receptor (GR) binding to GRE-dependent genes in vivo.
