Biochem/physiol Actions
Orally active retinoic acid (RA) metabolism blocking agent (RAMBA) with higher CYP26 specificity and potency than liarozole (R75251).
R115866 (Talarozole) is an orally active all-trans retinoic acid (RA) metabolism blocking agent (RAMBA; IC50 = 4 nM against RA metablism in yeast microsomes expressing human CYP26) with much reduced or little potency against CYP19 (aromatase), CYP17 (17,20-lyase), CYP2C11, CYP3A, and CYP2A1 (IC50 from 1.2 to >10 μM). Plasma and tissue RA upregulation via R115866 oral treatment exhibits in vivo efficacy in several retinoid-responsive rodent models, including vaginal keratinization suppression (ED50 = 1.0 mg/kg/day vs. 5.1 mg/kg/day with RA in rats), pinnal hyperplasia induction (ear epidermis thickness = 35.5 μm with 2.5 mg/kg/day R115866 vs. 16.5 μm in control mice), conversion of caudal para- to ortho-keratosis (90% with 1.25 mg/kg/day R115866 vs. 30.3% in control mice). Comparing to liarozole, R115866 is CYP26-selective and does not inhibit CYP-mediated biosynthesis of adrenal and gonadal steroid hormones.

Despite the fundamental importance of patterning along the dorsal-ventral (DV) and anterior-posterior (AP) axes during embryogenesis, uncertainty exists in the orientation of these axes for the mesoderm. Here we examine the origin and formation of the zebrafish kidney, a ventrolateral

Cytochrome P450 CYP26 enzymes are responsible for all-trans-retinoic acid (atRA) clearance. Inhibition of CYP26 enzymes will increase endogenous atRA concentrations and is an attractive therapeutic target. However, the selectivity and potency of the existing atRA metabolism inhibitors toward CYP26A1 and

During embryogenesis, tight regulation of retinoic acid (RA) availability is fundamental for normal development. In parallel to RA synthesis, a negative feedback loop controlled by RA catabolizing enzymes of the cytochrome P450 subfamily 26 (CYP26) is crucial. In vertebrates, the
