Effectively inhibits human Aldh1a2.
By Anonymous on 09/13/2019
Assay Type: In Vitro
Species: Human

This was used to inhibit recombinant Aldh1a2 activity in a titration curve.

Win-18446 showed an IC50 value at approximately 15 uM in a cell-free reaction assay. Was dissolved in DMSO to 100 mM with no solubility issues.
