Ro 41-5253 is an orally active selective retinoic acid receptor alpha (RARα) antagonist. Ro 41-5253 can bind RARα without inducing transcription or affecting RAR/RXR heterodimerization and DNA binding. Ro 41-5253 can inhibit cancer cell proliferation and induce apoptosis, has antitumor activity[1][2].
Ro 41-5253 (1 nM-10 μM, 10 days) significantly inhibits MCF-7 and ZR 75.1 cell proliferation and induces cell apoptosis in a time and dose-dependent manner[1].
Ro 41-5253 (oral gavage, 10-600 mg/kg, once a week, 4 weeks) can reduce tumor volume in female athymic Balb/mice transplanted with MCF-7 cell line[2].
