Vila, Laura published the artcileSynthesis and biological studies of “”Polycerasoidol”” and “”trans-δ-Tocotrienolic acid”” derivatives as PPARα and/or PPARγ agonists, Recommanded Product: Ethyl 4-oxopentanoate, the main research area is polycerasoidol trans tocotrienolic acid PPAR agonist receptor mol docking; 2-Prenylated benzopyrans; Grignard/Johnson-Claisen rearrangement; Polycerasoidol analogs; Tocotrienol analogs; Wittig olefination; hPPAR activity.
2-Prenylated benzopyrans represent a class of natural and synthetic compounds showing a wide range of significant activities. Polycerasoidol is a natural prenylated benzopyran isolated from the stem bark of Polyalthia cerasoides (Annonaceae) that exhibits dual PPARα/γ agonism and an anti-inflammatory effect by inhibiting mononuclear leukocyte adhesion to the dysfunctional endothelium. Herein, we report the synthesis of three new series of prenylated benzopyrans containing one (series 1), two (series 2, “”polycerasoidol”” analogs) and three (series 3, “”trans-δ-tocotrienolic acid”” analogs) isoprenoid units in the hydrocarbon side chain at the 2-position of the chroman-6-ol (6-hydroxy-dihydrobenzopyran) scaffold. Isoprenoid moieties were introduced through a Grignard reaction sequence, followed by Johnson-Claisen rearrangement and subsequent Wittig olefination. HPPAR transactivation activity and the structure activity relationships (SAR) of eleven novel synthesized 2-prenylated benzopyrans were explored. PPAR transactivation activity demonstrated that the seven-carbon side chain analogs (series 1) displayed selectivity for hPPARα, while the nine-carbon side chain analogs (polycerasoidol analogs, series 2) did so for hPPARγ. The side chain elongation to 11 or 13 carbons (series 3) resulted in weak dual PPARα/γ activation. Therefore, 2-prenylated benzopyrans of seven- and nine-carbon side chain (polycerasoidol analogs) are good lead compounds for developing useful candidates to prevent cardiovascular diseases associated with metabolic disorders.
