生物活性

MSI-1436 lactate is a selective, non-competitive inhibitor of the enzyme protein-tyrosine phosphatase 1B (PTP1B), with an IC50 of 1 μM, 200-fold preference over TCPTP (IC50 of 224 μM).

IC50 & Target

IC50: 1 μM (PTB1B), 224 μM (TCPTP)[1]

体外研究
(In Vitro)

MSI-1436's inhibition of TCPTP is less than the effect on PTP1B activity, with a resulting IC50 value of 224 μM[1]. MSI-1436 (Trodusquemine, 10 μM) restores ERK phosphorylation in response to mGluR1/5 agonist DHPG in F11 neuronal cells. MSI-1436 (10 uM) rescues DHPG-induced holding currents and restores DSI in LMO4KO BLA neurons[2]. MSI-1436 (0.1-100 μM) blocks PTP1B activity[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

MSI-1436 (10 mg/kg, i.p.) causes obesity-dependent body weight, reduces total body fat content and adipocyte size and lipid content of white adipose tissue of mice[1].
MSI-1436 (Trodusquemine) exhibits anxiolytic effect through a restoration of endocannabinoid (eCB) signaling within the amygdala[2].
MSI-1436 (5 mg/kg, i.p.) has an anti-diabetic effect on diabetic mice, and is sufficient to suppress food intake and cause weight loss in CD1 mice[3].

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: 5% DMSO    40% PEG300    5% Tween-80    50% Saline

    Solubility: ≥ 3 mg/mL (3.00 mM); 澄清溶液

Cell Assay
[1]

Quantitation of phosphatase activity is measured using an intact cell assay. Hep G2 cells are pretreated with 10 μM MSI-1436 lactate or sodium orthovanadate (100 μM, postive control) for 10 min at 37 °C, then incubated with 10 μM pNPP (a cell permeable hydrolysable substrate) for 30 min at 37 °C. Samples of the supernatants are spectrophotometrically analyzed at OD405 for hydolyzed pNP, a direct end product of phosphatase activity[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[1]

Male AKR/J mice are randomly placed on ad libitum 10, 45, or 60% fat kcal diets. After 14 weeks, mice are randomly assigned to three treatment groups (n=5 to 8 mice/group); MSI-1436 lactate (initial dose of 10 mg/kg with three subsequent weekly doses of 5 mg/kg, intraperitoneally), vehicle (saline, 10 mL/kg, weekly 4×), or pair-fed (PF). PF animals are injected with saline (weekly 4×) and allotted the amount of food consumed daily by MSI-1436 lactate -treated animals. On day 23, mice are anesthetized and euthanized for blood and tissue collection, respectively. Plasma is obtained following centrifugation of blood 14,000 rpm for 10 min at 4°C[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.
