YTX-465 is an inhibitor of both stearoyl-CoA desaturase(IC50s = 39 nM) and Ole1 (IC50s = 30.4 μM).
YTX-465 rescued growth to a similar magnitude but was >100-fold more potent than YTX-528(EC50 = 0.013 μM). Kinetic growth studies demonstrated that the most effective concentration of YTX-465 (0.050 μM) restored growth rates to that of approximately 40% of the wild-type strain treated with the same concentration of YTX-465[1]. In wild-type yeast, YTX-465 strongly reduced fatty desaturation in a concentration-dependent manner, with a 50% reduction in desaturation at 0.03 μM YTX-465[1].
