AT 1015 is a potent antagonist of 5-HT2A receptor [1].
The 5-HT2A receptor is a G protein-coupled receptor and a subtype of the 5-HT2 receptor, which belongs to the serotonin receptor family. The 5-HT2A receptor plays an important role in clathrin mediated endocytosis of JC virus, the human polyoma virus which causes progressive multifocal leukoencephalopathy (PML).
AT 1015 is a potent 5-HT2A receptor antagonist. AT 1015 bound to 5-HT2 receptors in rabbit cerebral cortex membrane with pKi value of 7.94 [1].
In a photochemically induced rat femoral arterial thrombosis (PIT) model, AT 1015 (1 mg/kg) significantly inhibited vascular contraction induced by 5-HT and prolonged the time for 24 h that required to occlusion of the artery in a dose-dependent way. While, AT 1015 (10 mg/kg) didn’t prolong bleeding time in the tail transection bleeding time test [2]. AT 1015 inhibited 5-HT2A receptor-mediated platelet aggregation both in vitro and in rat. In the rat peripheral vascular lesion model, AT 1015 (1 mg/kg) significantly inhibited progression of peripheral vascular lesions [3].
