A novel class of dual mPGES-1/5-LO inhibitors based on the α-naphthyl pirinixic acid scaffold
摘要:
Dual inhibition of microsomal prostaglandin E-2 synthase-1 (mPGES-1) and 5-lipoxygenase (5-LO) represents a promising strategy in the development of novel anti-inflammatory drugs targeting the arachidonic acid cascade. Herein, a class of alpha-naphthyl pirinixic acids is characterized as dual mPGES-1/5-LO inhibitors. Systematic structural variation was focused on the lipophilic backbone of the scaffold and yielded detailed structure-activity relationships (SAR) with compound 16 (IC50 mPGES-1 = 0.94 mu M; IC50 5-LO = 0.1 mu M) showing the most favorable in vitro pharmacological profile.

Peroxisome proliferator-activated receptor gamma (PPAR gamma) is involved in glucose and lipid homeostasis. PPAR gamma agonists are in clinical use for the treatment of type 2 diabetes. Lately, a new class of selective PPAR gamma modulators (SPPAR gamma Ms) was developed, which are believed to show less side effects than full PPAR gamma agonists. We have previously shown that alpha-substitution of pirinixic acid, a moderate agonist of PPAR alpha and PPAR gamma, leads to low micromolar active balanced dual agonists of PPAR alpha and PPAR alpha. Herein we present modifications of pirinixic acid leading to subtype-selective PPAR gamma agonists and furthermore the development of a selective PPAR gamma modulator guided by molecular docking studies.
