体外研究
(In Vitro)

PF-04991532 is a potent, hepatoselective glucokinase activator with EC50s of 80 nM in human and 100 nM in rat and also a Phase 2 clinical candidate. Mechanistic experiments conducted in freshly isolated primary rat hepatocytes treated for 1 hour with PF-04991532 show increased 2-[14C]-deoxyglucose uptake (EC50 =1.261 μM) and increased glucose oxidation (EC50=5.769 μM). Additionally, PF-04991532 decreases the production of glucose from 1-[14C]-lactate in a dose dependent manner (EC50 =0.626 μM). In isolated rat hepatocytes, PF-04991532 increases the expression of G6Pase compare to cells treated only with 100 nM glucagon, and the greatest increase in G6Pase mRNA expression is in the presence of 25 mM glucose, 100 nM glucagon and PF-04991532[1].

体内研究
(In Vivo)

A single dose of PF-04991532 increases the glucose infusion rate in order to maintain hyperglycemia. Despite the elevations in plasma triglycerides, surprisingly, hepatic triglycerides in rats dosed with 19 days of PF-04991532 are identical to vehicle treated GK rats. In an additional cohort treated for 28 days, identical hepatic lipid concentrations are observed between vehicle and rats dosed with PF-04991532 (Vehicle: 9.89±0.31; PF-04991532 100 mg/kg: 9.91±0.31). In rats treated with PF-04991532, there is increased expression of lipogenic gene expression such as acetyl-CoA carboxylase (ACC), ATP citrate lyase (ACLY), and fatty acid synthase (FAS)[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 (5.25 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。

    以 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% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (5.25 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。

    以 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 20% 的 SBE-β-CD 生理盐水水溶液 中，混合均匀。

    2 g SBE-β-CD（磺丁基醚 β-环糊精）粉末定容于 10 mL 的生理盐水中，完全溶解至澄清透明。

Cell Assay
[1]

Primary rat hepatocytes are used to determine the expression of G6Pase. 50,000 freshly isolated rat hepatocytes are incubated in Williams E media overnight supplemented with 100 nM dexamethasone, 1×ITS, and 1×PenStrep. The following morning the media is aspirated, and changed to DMEM no glucose media supplemented with either 5 mM glucose, 25 mM glucose, 1 µM insulin, 100 nM glucagon, or 10 µM PF-04991532. Following 2 hours the media is aspirated, washed twice, and 100 µL of RLT is added to the cells. RNA is extracted with a RNeasy kit[1].

Animal Administration
[1]

13 week old male Goto Kakizaki rats with in-dwelling carotid artery and jugular vein catheters are used in this study. Surgeries are performed one day before shipping. Upon arrival, animals are individually housed, allowed ad libitum chow, and acclimated to their new environment for 6 to 7 days. Animals are randomly assigned either a 100 mg/kg PF-04991532 treatment or vehicle control treatment and orally gavaged at 5 mL/kg. On the day of the experiment, 0.5% Methyl cellulose vehicle is used in vehicle-treated rats. Studies are performed in unstressed, awake, chronically catheterized rats using the insulin clamp technique, in combination with [3-3H] glucose. At the end of the in vivo studies, rats are euthanized[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.
