Conformationally Defined Rexinoids for the Prevention of Inflammation and Nonmelanoma Skin Cancers.
J.Med.Chem., 65:14409-14423, 2022

PubMed Abstract: Compound is a potent rexinoid that is highly effective in cancer chemoprevention but elevates serum triglycerides. In an effort to separate the lipid toxicity from the anticancer activity of , we synthesized four new analogs of rexinoid , of which three rexinoids did not elevate serum triglycerides. Rexinoids and are twice as potent as rexinoid in binding to Retinoid X receptor (RXR). retinoic acid (ATRA) plays a key role in maintaining skin homeostasis, and rexinoids are highly effective in upregulating the genes responsible for the biosynthesis of ATRA. Inflammation plays a key role in skin cancer, and rexinoids and are highly effective in diminishing LPS-induced inflammation. Rexinoids and are highly effective in preventing UVB-induced nonmelanoma skin cancer (NMSC) without displaying any overt toxicities. Biophysical studies of rexinoids and bound to hRXRα-ligand binding domain (LBD) reveal important conformational and dynamical differences in the ligand binding domain.
