生物活性

BIIE-0246 is a potent and highly selective non-peptide neuropeptide Y (NPY) Y2 receptor antagonist, with an IC50 of 15 nM.

性状

Solid

IC50 & Target[1][2]

NPY Y2 receptor

15±3 nM (IC50)

体外研究(In Vitro)

Receptor binding assays in HEK 293 cells transfected with the rat Y2 receptor cDNA demonstrate that BIIE-0246 competes with high affinity (IC50=15±3 nM) against specific [I]PYY3-36 binding sites. In contrast, BIIE-0246, at concentrations up to 10 μM, fails to compete for significant amounts of specific [I]GR231118, [I]hPP and [I][Leu, Pro]PYY binding sites in HEK 293 cells transfected with the rat Y1, Y4 or Y5 receptor cDNA, respectively.

体内研究(In Vivo)

On chow diet, genetically obese NPY mice show increased gain in body weight and adiposity. Treatment with BIIE-0246 promotes body weight gain in both genotypes after 4.5 weeks, and already at 2 weeks. BIIE-0246 has no significant effect on fat mass gain. In DIO, BIIE-0246 has different effects on body weight and composition depending on the genotype (treatment×genotype interaction in body weight P<0.05, in fat mass P<0.001 and in lean mass P<0.05). In DIO-WT group, post hoc analysis reveals increased body weight and fat mass gain, and a tendency to decrease lean mass gain. In DIO-NPY, BIIE-0246 inhibits fat mass gain (P=0.05). Interestingly, increased cholesterol levels are detected also in WT mice treated with BIIE-0246 for 2 weeks, but not in the 4.5-week cohort. In DIO-NPY mice in both treatment groups, cholesterol levels correlate positively with body fat mass (DIO-NPY vehicle P<0.01; DIO-NPY BIIE-0246 P<0.001), but not in any other group, and the slope of the regression curve of cholesterol and fat mass is significantly decreased in BIIE-0246-treated DIO-NPY group when compared with vehicle-treated group.

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。
