Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors and members of the nuclear hormone receptor superfamily. Herein, we describe an efficient synthesis of a novel isosteric selenium analog of the highly specific PPARβ/δ ligand 2-methyl-4-((4-methyl-2-(4-trifluoromethylphenyl)-1,3-thiazol-5-yl)-meth ylsulfanyl)phenoxy-acetic acid (GW501516; 1). The study examined the efficiency of the novel selenium analog 2-methyl-4-((4-methyl-2-(4-trifluoromethylphenyl)-1,3-selenazol-5-yl)-me thylsulfanyl)phenoxy-acetic acid (2) to activate PPARβ/δ and the effect of ligand activation of PPARβ/δ on cell proliferation and target gene expression in human HaCaT keratinocytes. The results showed that similar to GW501516, the Se-analog 2 increased expression of the known PPARβ/δ target gene angiopoietin-like protein 4 (ANGPTL4); the compound 2 was comparable in efficacy as compared to GW501516. Consistent with a large body of evidence, the Se-analog inhibited cell proliferation in HaCaT keratinocytes similar to that observed with GW501516. In summary, the novel Se-analog 2 has been developed as a potent PPARβ/δ ligand that may possess additional anti-cancer properties of selenium.
