Tideglusib (CAS 865854-05-3) is a high-purity GSK-3 inhibitor API with a targeted kinase-suppressing mechanism. As a potent and selective inhibitor of glycogen synthase kinase 3 (GSK-3α/β), it modulates key cellular signaling pathways involved in neuroprotection, inflammation, and cell survival. Its refined crystalline form ensures consistent bioactivity and ultra-low impurity levels, making it a reliable tool for pharmaceutical R&D.
