Product Introduction

Bioactivity
Description
SID 26681509 is a selective, reversible and competitive human cathepsin L inhibitor (IC50 of 56 nM).
Targets&IC50
Cathepsin L (human):56 nM , Leishmania major:12.5 μM , P. falciparum:15.4 μM
In vitro
After a 4-hour preincubation with cathepsin L, SID 26681509 becomes more potent (IC50: 1.0 nM). SID 26681509 acts as a slow-binding, slowly reversible competitive inhibitor with inhibition rate constants kon = 24,000 M^-1s^-1 and koff = 2.2 × 10^-5 s^-1 (Ki = 0.89 nM), as determined through transient kinetic analysis for single-step reversibility. Molecular docking studies, using the X-ray crystal structure of papain/CLIK-148[1], show that SID 26681509 inhibits papain and cathepsins B, K, S, and V with IC50 values ranging from 618 nM to 8.442 μM after one hour[1].
In vivo
survival in murine models of sepsis significantly improved SID 26681509 by and reduces liver damage following warm liver ischemia/reperfusion (I/R) models[2].

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
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
