ER 50891
Based on 1 Customer Validation
ER 50891 is a RARα antagonist. ER 50891 can significantly antagonize the inhibitory effect of all-trans retinoic acid (ATRA) on the total cell metabolic activity and proliferation of MC3T3-E1 preosteoblasts. ER 50891 rescues ATRA-inhibited osteocalcin (OCN) expression and extracellular matrix mineralization, and suppresses alkaline phosphatase (ALP) activity synergistically. ER 50891 can be used for the study of osteoporosis related to ATRA-induced inhibition of osteoblastogenesis.

ER 50891 (1-3 μM, 3 days) significantly promotes total cell metabolic activity of MC3T3-E1 preosteoblasts alone and antagonizes the inhibitory effect of ATRA on total cell metabolic activity[1].
ER 50891 (0.25-3 μM, 3 days) dose-dependently relieves the inhibition of 1 μM ATRA on OCN expression in MC3T3-E1 preosteoblasts[1].
ER 50891 (1.5-3 μM, 19 days) rescues the extracellular matrix mineralization of MC3T3-E1 preosteoblasts inhibited by ATRA[1].
