生物活性

LY2562175 is a potent and selective FXR agonist, with an EC50 of 193 nM[1].

IC50 & Target

EC50: 193 nM (FXR)

体外研究
(In Vitro)

LY2562175 promotes transcriptional activation of human FXR in a cell-based co-transfection assay with an EC50 of 193 nM. LY2562175 promotes recruitment of a peptide from the nuclear receptor interaction domain of the coactivator SRC-1 with a relative EC50 of 121 nM and 93.5% efficacy as compare to GW4064[1].

体内研究
(In Vivo)

LY2562175 causes a dose-dependent decrease in serum cholesterol and serum triglycerides. At a dose of 10 mg/kg, the decrease in cholesterol with LY2562175 is 80% below vehicle-treated animals, and the decrease in serum triglycerides is 76% from control group. The ED50 for serum cholesterol is determined to be 2 and 3.4 mg/kg for serum triglycerides. Treatment of female ZDF rats with LY2562175 results in a dose dependent lowering of plasma triglycerides in the fasted and nonfasted states. When administered as a fixed dose combination with BRL49653, LY2562175 further lowers fasted and nonfasted plasma triglycerides. FPLC fractionation of the lipoproteins reveals that LY2562175 treatment results in a reduction in vLDL-C and a dramatic increase in HDL-c in this animal model[1].

动物实验:

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (3.85 mM); 澄清溶液

    此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

    生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。
  • 方案 二

    请依序添加每种溶剂: 10% DMSO    90% Corn Oil

    Solubility: ≥ 2.08 mg/mL (3.85 mM); 澄清溶液

    此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。

    1 mL 工作液为例,取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。

Kinase Assay
[1]

LY2562175 is tested in concentration-response curves by an FXR-SRC-1 Cofactor Recruitment assay using the Alpha Screen technology according to the manufacturer instructions. Briefly, purified 6-HIS-tagged human FXR ligand-binding domain (amino acids 242-472), purified GST-tagged human SRC-1 nuclear receptor-interacting domain (amino acids 220-394), Nickel Chelate donor beads and Anti-GST antibody acceptor beads are mixed together and 12 μL per well is aliquoted into 384 well plates. Add LY2562175 in 3 μL per well for a total assay volume of 15 μL and incubate at room temperature in the dark for 4 hours. After incubation, LY2562175 that binds FXR and induces the interaction between the FXR and SRC-1 will bring the two bead types into proximity generating luminescence that is quantified using a Packard Fusion instrument. Calculate EC50 values for LY2562175[1].

Animal Administration
[1]

To assess the potency and efficacy of LY2562175 in vivo, studies are conducted in 8 week old, male LDLR null mice fed a “Western” diet. Animals are allowed to acclimate to the high fat/high cholesterol chow TD88137 (containing 0.15% cholesterol and 42% fat) for 2 weeks prior to the study. Animals are divided into groups of six and dosed once daily for 1 week by gavage with solutions of LY2562175 in situ sodium salt or with vehicle (5% Solutol, 5% EtOH, 1 wt %/v CMC) at a dose volume of 5 mL/kg. On the seventh day, animals are bled by cardiac puncture under anesthesia with CO2. Serum is prepared from individual animals for determination of cholesterol and triglycerides by enzymatic analysis. Pooled samples from each treatment group are used for determination of lipoprotein subtypes. ED50 values (dose producing half-maximal effect) for the decrease in serum cholesterol and triglycerides are determined by nonlinear regression analysis[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
