Product Introduction

Bioactivity
Description
ML133 hydrochloride (ML133 HCl) is a selective potassium channel inhibitor for Kir2.1 with IC50 of 1.8 μM (pH 7.4) and 290 nM (pH 8.5), has no effect on Kir1.1 and weak activity for Kir4.1 and Kir7.1.
Targets&IC50
KIR2.1 (pH 8.5):290 nM, KIR2.1 (pH 7.4):1.8 μM
In vitro
The ratio of total concentration of extracellular ML133 versus intracellular ML133 is 1:0.13 at pH 6.5, 1:9.09 at pH 8.5. ML133 is clean against 3A4 and 2C9 (IC50 >30 μM), displays moderate inhibition of 1A2 (IC50 = 3.3 μM) but proves to be a potent inhibitor of 2D6 (IC50 = 0.13 μM) in CYP450 assay. ML133 is highly protein bound (>99%) in both human and rat and also displays high intrinsic clearance in both species. ML133 (10 μM) is not displaced by K+ influx from the wild-type Kir2.1 in HEK 293 cells. M1 and/or M2 transmembrane domains contain the critical molecular determinant for ML133 inhibition of Kir2.1, especially D172 and I176. [1]

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
