AGN 193109 is a potent antagonist of retinoic acid receptors (RARs; Kd= 2, 2, and 3 nM for RARα, β, and γ, respectively), exhibiting selectivity for RARs over retinoid X receptors (RXRs; Kd= >10,000 nM for human RXRα, β, and γ receptors). This compound effectively reverses cellular morphology changes and growth suppression induced by RAR agonists such as all-trans-RA, 13-cis-RA, and 9-cis-RA in ECE16-1 human endometrial ectocervical epithelial cells, particularly when used at a 10-fold molar excess. Furthermore, AGN 193109 downregulates the expression of cytokeratin K5-8, 13, 14, 16, 17, and 19 genes, indicating inhibition of retinoid action, specifically when co-administered with TTNPB but not as a standalone treatment. In vivo studies demonstrate teratogenic effects, including cleft palate, frontonasal dysplasia, and eye malformations in mouse fetuses following a single oral dose of 1 mg kg.
AGN-191129, also known as Prostaglandin F2α alcohol methyl ether (PGF2α-OMe), is an analog of PGF2α in which the C-1 carboxyl group has been replaced by an O-methyl ether. The compound is reported to retain ocular hypotensive properties, but the receptors
AGN 195183 is a potent and selective agonist of RARα(Kd=3 nM) with improved binding selectivity relative to AGN 193836; no activity on RARβ/γ. IC50 value: 3 nM (Kd); 200 nM (EC80, RAR Trans.) Target: RARα agonist Compound 4(AGN-195183) inhibited the growt
AGN194204 (IRX4204) is inactive against RAR and is an orally active and selective RXR agonist with Kd values 0.4 nM, 3.6 nM and 3.8 nM and EC50s of 0.2 nM, 0.8 nM and 0.08 nM for RXRα, RXRβ and RXRγ, respectively. AGN194204 has anti-inflammatory and antic
KSK213 is a potent inhibitor of Chlamydia trachomatis Infectivity (EC50 = 60 nM). KSK213 potently inhibited multiple serovars of C. trachomatis while not affecting the growth of key species from the commensal flora or host cell viability at 25 μM.
