YTX-465 is a stearoyl-CoA desaturase (Ole1/SCD) inhibitor. YTX-465 inhibits Ole1 and SCD1 with IC 50 s of 0.039 μM and 30.4 μM, respectively. YTX-465 can be used in the research of Parkinson’s disease and other synucleinopathies In Vitro YTX-465 (1-10000 nM) has an EC 50 value of 0.013 μM for α-synuclein (α-syn) toxicity rescue. YTX-465 (0.05 μM; 0-2 days) rescue the growth of α-Syn-expressing yeast. YTX-465 (0, 10, 40, 160, 640, 2500 nM; 4h) increases the level of Ole1 protein in wild-type yeast expressing OLE1 in a concentration-dependent manner, that indicate YTX-465 induce a negative feedback loop. YTX-465 (0, 0.03, 0.09, 0.27, 0.81 μM; 6 hours) reduces fatty desaturation in a concentration-dependent manner in wild-type yeast, with a 50% reduction in desaturation at 0.03 μM. YTX-465 (0.25 μM; 8 hours) decreases the desaturation index (DI) for all major classes of membrane phospholipids in wild-type yeast. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:Ole1 0.039 μM (IC 50 ) SCD1 30.4 μM (IC 50 )
