AGN 193109 is an orally active retinoic acid receptor (RAR) antagonist that 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.
High-affinity orally active pan-retinoic acid receptor (RAR) antagonist with in vitro and in vivo efficacy.
PPARγ, a ligand-activated nuclear receptor, regulates fundamental aspects of bone homeostasis and skeletal remodeling. PPARγ-activating anti-diabetic thiazolidinediones in clinical use promote marrow adiposity, bone loss, and skeletal fractures. As such, delineating novel regulatory pathways that modulate the action of PPARγ
The differential programming of sperm and eggs in gonads is a fundamental topic in reproductive biology. Although the sexual fate of germ cells is believed to be determined by signaling factors from sexually differentiated somatic cells in fetal gonads, the

The synthetic retinoid AGN 193109 is a potent pan retinoic acid receptor (RAR) antagonist. Treatment of pregnant mice with a single oral 1 mg/kg dose of this antagonist on day 8 postcoitum results in severe craniofacial (median cleft face or
The amyloid-β peptide or Aβ is the key player in the amyloid-cascade hypothesis of Alzheimer's disease. Aβ appears to trigger cell death but also production of double-strand breaks (DSBs) in aging and Alzheimer's disease. All-trans retinoic acid (RA), a derivative

Multiple fetal anomalies occur in vitamin A deficient animals as well as in retinoic acid receptor gene 'knockout' mice, indicating that retinoic acid (an active metabolite of vitamin A) performs some essential functions in normal development. Additional approaches are needed
