BMS 649 is a synthetic retinoid and retinoid X receptor (RXR) agonist.1 It binds to RXRα homodimers and selectively induces transactivation in CV-1 cells expressing RXRα over CV-1 cells expressing retinoic acid receptor α (RARα), RARβ, or RARα and RXRα when used at a concentration of 0.1 µM. BMS 649 (1 µM), in combination with the RARα agonist BMS 753, induces morphological differentiation of F9 embryonal carcinoma cells.2 It prevents differentiation induced by phorbol-12-myristate-13-acetate (PMA; Item No. 10008014) of THP-1 monocytes into macrophages.3 BMS 649 (25 mg/kg) reduces body weight and bone lengths when administered to newborn rats.4 It induces malformations in Xenopus embryos.5
