Peroxisome proliferator-
activated receptor (PPAR) γ is a nuclear receptor that, when activated, regulates fatty acid storage and glucose metabolism.
1 The best known class of PPARγ ligands are the thiazolidinediones, including troglitazone (Item No.
71750) and rosiglitazone (Item No.
71740).
2 GW 1929 is a non-
thiazolidinedione activator of PPARγ that binds with a K
i value of 1.4 nM, with greater than 1,000-
fold selectivity over other PPAR subtypes.
3 It has anti-
hyperglycemic and anti-
hyperlipidemic activity when given orally in mouse and rat models of type 2 diabetes.
3,4 Both
in vitro and
in vivo effects of GW 1929 on PPARγ greatly exceed those produced by troglitazone.
3,4 In addition, GW 1929 has neuroprotective effects in global cerebral ischemic-
reperfusion injury that are related to reduced inflammation and apoptotic DNA fragmentation.
