Uses
As a retinoic acid receptor (RAR) antagonist, 4-{[5,5-dimethyl-8-(4-methylphenyl)-5,6-dihydronaphthalen-2-yl]ethynyl}benzoic acid can be used for treating chemotherapy and radiation therapy side effects.
Biological Activity
AGN 193109 is an orally active retinoic acid receptor (RAR) antagonist th at targets all three RAR subtypes with higher affinity (RARα/β/γ Kd = 2 nM) than all-trans retinoic acid/ATRA (RARα/β/γ Kd = 9/12/19 nM). AGN 193109 potently antagonizes against ATRA-induced transcription in RARα, RARβ, and RARγ transfected CV-1 cells (by 85%, 62%, and 100%, respectively, by equal molar AGN 193109 against ATRA). AGN 193109 is also widely employeed to block RAR-mediated physiological and pathalogical processes in mice and rats in vivo via oral (1-10 mg/kg) or topical (0.3-36 μmol/kg) administration.
