What is SR 202?

The Uses of SR 202

SR 202 is a noniodinated, potential lipid-altering agent and an inhibitor of the peripheral conversion of T4 to T3 associated with thyroid hormone metabolism.

The Uses of SR 202

Anti-atherosclerotic.

What are the applications of Application

SR 202 is a selective PPARγ antagonist

Definition

ChEBI: Phosphoric acid [(4-chlorophenyl)-dimethoxyphosphorylmethyl] dimethyl ester is a trialkyl phosphate.

brand name

Clenicor (Symphar S.A.,Switzerland).

Biological Activity

Selective PPAR γ antagonist; antidiabetic and antiobesity agent. Attenuates troglitazone-induced PPAR γ transcriptional activity (IC 50 = 140 μ M) without affecting ligand-stimulated PPAR α , PPAR β or FXR transcriptional activity. Inhibits PPAR γ -dependent adipocyte differentiation and growth in vitro and in vivo . Improves insulin sensitivity in diabetic ob/ob mice and increases HDL levels in rats in vivo .

in vitro

sr-202 is a specific antagonist of ppar, which shows selectivity both among the ppar family members and other nuclear receptors. sr-202 also inhibits ppar-dependent differentiation of adipocytes. in cell culture, sr-202 efficiently antagonizes hormone- and tzd induced adipocyte differentiation [1].

in vivo

. decreasing ppar activity by treatment with sr-202 leads to a reduction of both high fat diet-induced adipocyte hypertrophy and insulin resistance. treatment with sr-202 also dramatically improves insulin sensitivity in the diabetic ob/ob mice [1]. when wild-type mice are fed a high-fat diet, the plasma levels of tnf-α are raised, and sr-202 treatment protects against this rise [2]..

Storage

Desiccate at RT
