GW0742

GW0742 is a potent PPARβ and PPARδ agonist, with an IC₅₀ of 1 nM for human PPARδ in binding assay, and EC₅₀s of 1 nM, 1.1 μM and 2 μM for human PPARδ, PPARα, and PPARγ, respectively. IC50 & Target:IC50: 1 nM (Human PPARδ)^[1]
EC50: 1 nM (Human PPARδ), 1.1 μM (Human PPARα), 2 μM (Human PPARγ)^[1]
PPARβ^[2] In Vitro: GW0742 is a potent PPARβ and PPARδ agonist, with an IC₅₀ of 1 nM for human PPARδ, and EC₅₀s of 1 nM, 1.1 μM and 2 μM for human PPARδ, PPARα, and PPARγ respectively^[1]. GW0742 (100 μM) activates human PPARα and mouse PPARβ in MCF-7 cells. GW0742 (100 μM) significantly reduces low-KCl-induced apoptosis of cerebellar granule neurons. GW0742 shows no obvious inherent toxicity on cerebellar granule neuronal cells after treatment of 3-100 μM for 24 h, but induces increased cell death at 100 μM after 48 hr of treatment. Moreover, GW0742 (100 μM) increases c-Jun expression in cerebellar granule neuron cultures observed at 6 hr^[2]. GW0742 (1 μM) induces PPARδ protein in neonatal rat cardiomyocytes. GW0742 also raises mRNA levels of long-chain acyl-CoA dehydrogenase (LCAD), very long-chain acyl-CoA dehydrogenase (VLCAD), acyl-CoA oxidase 1 (ACOX1), uncoupling protein 3 (UCP3), malonyl-CoA decarboxylase (MCD), and pyruvate dehydrogenase kinase 4 (PDK4) in neonatal rat cardiomyocytes^[4]. In Vivo: GW0742 (0.3 mg/kg, i.p.) reduces intensity masson-trichrome staining, and attenuates the histological signs in bleomycin instillatio (BLEO)-induced lung injury of mice. GW0742 (0.3 mg/kg, i.p.) also causes a reduction of the BLEO-induced loss body weight, and a decrease of myeloperoxidase (MPO) activity. GW0742 shows significant inhibition of TNF-a and IL-1β in instilled-mice. GW0742 prevents bleomycin-induced IkB-a degradation, reduces the levels of NF-kB p65 in the lung, and decreases iNOS and p-ERK expression in BLEO-induced mice^[3]. GW0742 (5 mg/kg/day, i.v.) increases PPARδ protein level in the heart of rats. GW0742 also induces the increase in LCAD, VLCAD, and ACOX1 in the heart of rats^[4].
