Biological Activity

Description UK-371804 is a potent and selective urokinase-type plasmogen activator (uPA) inhibitor with excellent enzyme potency (Ki=10 nM) and selectivity profile (4000-fold versus tPA and 2700-fold versus plasmin).
Targets
uPA [1]
(Cell-free assay)
10 nM(Ki)
In vitro

In Vitro, UK-3718046 is able to inhibit exogenous uPA in human chronic wound fluid (IC50=0.89 µM)[1].
In vivo In Vivo, in a porcine acute excisional wound model, following topical delivery, UK-3718046 is able to penetrate into pig wounds and inhibit exogenous uPA activity with no adverse effect on wound healing parameters[1].

Protocol (from reference)

Animal Research:[1]
  • Animal Models: A porcine acute excisional wound model
  • Dosages: 10 mg/mL
  • Administration: topical delivery
  • (Only for Reference)

Solubility (25°C)

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
