Biological Activity
IC50: 1 μM (PTB1B), 224 μM (TCPTP)[1]
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].

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].

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
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].

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].
