BMS453 (BMS-189453), a synthetic retinoid, is a RARβ agonist and a RARα/RARγ antagonist. BMS453 inhibits breast cell growth predominantly through the induction of active TGFβ.

体外研究(In Vitro)
BMS453 (1 μM; 11 hours; 184 and HMEC cells) treatment inhibits the proliferation of normal breast cell growth without significantly inducing apoptosis.
BMS453 (1 μM; 5 days; 184 and HMEC cells) treatment inhibits normal breast cell proliferation by causing G1 arrest.
BMS453 (1 μM; 24-72 hours; 184 cells) treatment induces Rb hypophosphorylation and decrease CDK2 kinase activity. BMS453 increases total p21 protein levels and CDK2-bound p21 protein, but does not change CDK4-bound p21.
BMS453 inhibits breast cell growth predominantly through the induction of active TGFβ.
