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).
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 (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].
