Off-White Solid

A cell-permeable chloro-nitro-benzamido compound that acts as a potent, specific, irreversible, and high-affinity antagonist of PPAR with a Ki of 1 nM. Displays >800-fold greater selectivity for PPAR over PPARa and PPARd (Ki = 0.85 and 1.8 ,

Potent and selective PPAR γ antagonist (IC 50 = 1 nM). Displays > 800-fold selectivity for PPAR γ over PPAR α and PPAR δ . In vitro, blocks transcriptional activity of PPAR γ and inhibits rosiglitazone-induced adipogenesis.

The peroxisome proliferator-activated receptor-γ (PPARγ) is the nuclear receptor responsible for transducing the therapeutic activity of the thiazolidinediones (TZDs). TZDs are a group of structurally related synthetic PPARγ receptor agonists with antidiabetic actions in vivo. There are many PPARγ agonists, including 15-deoxy-Δ^12,14-prostaglandin J₂ and azelaoyl PAF, which are naturally derived. However, only a few antagonists have been reported. T0070907 is a potent and selective antagonist of the human PPARγ with an apparent IC₅₀ of 1 nM for the binding inhibition of rosiglitazone, a reference TZD. T0070907 covalently binds to Cys³¹³ of PPARγ, inducing conformational changes that block the recruitment of transcriptional cofactors to the PPARγ/RXR heterodimer.

ChEBI: 2-chloro-5-nitro-N-pyridin-4-ylbenzamide is a carbonyl compound and an organohalogen compound.

T0070907 is very similar in structure and activity to the PPAR-γ antagonist GW9662. T0070907 is more potent and has higher selectivity for PPAR-γ over all other subtypes (about 800-fold) whereas GW9662 has been reported to have some PPAR-α agonist activity.
