The design and synthesis of triple-acting PPARα, -γ, and -δ agonist 3-(2-ethyl-4-2-[2-(4-fluorophenyl)-5-methyloxazol-4-yl]ethoxy}phenyl)propanoic acid (1a) is described. The compound possesses a potent triple-acting PPARα, -γ, and -δ agonist profile with an EC50 of 0.029, 0.013, and 0.029 µM, respectively. The synthetic route, involving the synthesis of oxazole rings as the key step, starts from commercially available 3-oxopentanoic acid methyl ester and 3-hydroxyacetophenone to afford the target compound 1 with an overall yield of 32%.
本文描述了三重作用PPARα、-γ和-δ激动剂3-(2-乙基-4-2-[2-(4-氟苯基)-5-甲基噁唑-4-基]乙氧基}苯基)丙酸(1a)的设计与合成。该化合物具有强大的三重作用PPARα、-γ和-δ激动剂特性,其EC50值分别为0.029、0.013和0.029 µM。合成路线以噁唑环的合成为关键步骤,从市售的3-氧代戊酸甲酯和3-羟基苯乙酮出发,最终得到目标化合物1,总产率为32%。
