A ligand-based virtual screening exercise examining likely bioactive conformations of AM 580 (2) and AGN 193836 (3) was used to identify the novel, less lipophilic RARα agonist 4-(3,5-dichloro-4-ethoxybenzamido)benzoic acid 5, which has good selectivity over the RARβ and RARγ receptors. Analysis of the medicinal chemistry parameters of the 3,5-substituents of derivatives of template 5 enabled us to design a class of drug-like molecules with lower intrinsic clearance and higher oral bioavailability which led to the novel RARα agonist 4-(3-chloro-4-ethoxy-5-isopropoxybenzamido)-2-methylbenzoic acid 56 that has high RARα potency and excellent selectivity versus RARβ (2 orders of magnitude) and RARγ (4 orders of magnitude) at both the human and mouse RAR receptors with improved drug-like properties. This RARα specific agonist 56 has high oral bioavailability (>80%) in both mice and dogs with a good PK profile and was shown to be inactive in cytotoxicity and genotoxicity screens.

The present invention encompasses compounds of Formula A: A as well as the pharmaceutically acceptable salts thereof. The compounds are S1P1/Edg1 receptor agonists and thus have immunosuppressive, anti-inflammatory and hemostatic activities by modulating leukocyte trafficking, sequestering lymphocytes in secondary lymphoid tissues, and enhancing vascular integrity. The invention is also directed to pharmaceutical compositions containing such compounds and methods of treatment or prevention.
