BMS 270394 is an agonist of retinoic acid receptor γ (RARγ; EC50 = 30 nM in a transactivation assay) and the active enantiomer of BMS 189961 .1 It is selective for RARγ over RARβ (EC50 = 400 nM) and is inactive at RARα. BMS 270394 synergizes with paclitaxel to inhibit the growth of MCF-7 breast and OVCAR-3 ovarian cancer, as well as SqCC/Y1 head and neck squamous cell carcinoma, cells.2
