  Evolution of a 4-Benzyloxy-benzylamino Chemotype to Provide Efficacious, Potent, and Isoform Selective PPARα Agonists as Leads for Retinal Disorders

  摘要：

  Peroxisome proliferator-activated receptor alpha (PPAR alpha) is expressed in retinal Muller cells, endothelial cells, and in retinal pigment epithelium; agonism of PPAR alpha with genetic or pharmacological tools ameliorates inflammation, vascular leakage, neurodegeneration, and neovascularization associated with retinal diseases in animal models. As such, PPAR alpha is a promising drug target for diabetic retinopathy and age-related macular degeneration. Herein, we report proof-of-concept in vivo efficacy in an streptozotocin-induced vascular leakage model (rat) and preliminary pharmacokinetic assessment of a first-generation lead 4a (A91). Additionally, we present the design, synthesis, and evaluation of second-generation analogues, which led to the discovery of 4u and related compounds that reach cellular potencies <50 nM and exhibit >2,700-fold selectivity for PPAR alpha over other PPAR isoforms. These studies identify a pipeline of candidates positioned for detailed PK/PD and pre-clinical evaluation.

  Novel thiazolidinedione derivatives with anti-obesity effects: Dual action as PTP1B inhibitors and PPAR-γ activators

  摘要：

  Benzylidene-2,4-thiazolidinedione derivatives with substitutions at both the ortho and para-positions of the phenyl group were synthesized as PTP1B inhibitors with IC50 values in a low micromolar range. Compound 18l, the lowest, bore an IC50 of 1.3 mu M. In a peroxisome proliferator-activated receptor-gamma (PPAR-gamma) promoter reporter gene assay, 18l was found to activate the transcription of the reporter gene with potencies comparable to those of troglitazone, rosiglitazone, and pioglitazone. In vivo efficacy of 18l as an anti-obesity and hypoglycemic agent was evaluated in a mouse model system. Compound 18l significantly suppressed weight gain and significantly improved blood parameters such as TG, total cholesterol and NEFA without overt toxic effects. (C) 2010 Elsevier Ltd.
