Products Description
What is O-304 CAS 1261289-04-6 ATX-304 Powder?
O-304 (CAS No. 1261289-04-6) is a novel, first-in-class, orally bioavailable pan-AMPK activator widely used in biomedical research and pharmaceutical preclinical studies. Also known as 4-chloro-N-(2-(4-chlorobenzyl)-3-oxo-2,3-dihydro-1,2,4-thiadiazol-5-yl)benzamide, this compound effectively activates AMP-activated protein kinase (AMPK) by inhibiting the dephosphorylation of phosphorylated AMPK, delivering stable and significant biological activity.
As a critical research chemical and drug candidate material, O-304 shows excellent potential in studying type 2 diabetes, insulin resistance, and cardiovascular complications. We provide high-purity O-304 powder with strict quality control, complete test reports, and flexible packaging solutions to meet global laboratory and pharmaceutical research demands.
