生物活性

GW-1100 is a selective GPR40 antagonist with a pIC₅₀ of 6.9.

性状

Solid

IC50 & Target[1][2]

pIC50: 6.9 (GPR40)

体外研究(In Vitro)

GW-1100 (GW1100) dose dependently inhibits GPR40-mediated Ca elevations stimulated by GW9508 and linoleic acid (pIC₅₀ values of 5.99±0.03 and 5.99±0.06, respectively). GW-1100 at a concentration of 1 μM produces a significant rightward shift in the concentration-response curve to GW9508 (pEC₅₀=7.17±0.08 in the absence and pEC₅₀=6.79±0.09 in the presence of 1 μM GW-1100; P<0.05; n=3). At concentrations of GW-1100 of 3 μM and higher a significant decrease in the maximal response is observed with a continuing rightward shift in the pEC₅₀ response. GW-1100 (GW1100) reduces FFAR1 ligand-induced intracellular calcium in CHO-K1/bFFAR1 cells and neutrophils. CHO-K1/bFFAR1 cells are incubated for 15 min with 10 μM GW1100 or vehicle (0.1% DMSO) and then stimulated with vehicle, oleic acid, linoleic acid or GW9508. GW-1100 significantly reduces the increase in intracellular calcium induced by 300 μM oleic acid (AUC_{(60-150 s)}, p<0.05), 100 μM linoleic acid (AUC_{(60-150 s)}, p<0.05) and 10 μM GW9508 (AUC_{(60-150 s)}, p<0.05).

体内研究(In Vivo)

The intracerebroventricular injection of DHA (50 μg) and GW9508 (1.0 μg), a GPR40-selective agonist, significantly reduces mechanical allodynia and thermal hyperalgesia at day 7, but not at day 1, after CFA injection. These effects are inhibited by intracerebroventricular pretreatment with GW-1100 (10 μg), a GPR40 antagonist.

Data Sheet

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
