MT-1207
Based on 1 Customer Validation
MT-1207 is an orally active, selective adrenergic α1 and 5-HT2A receptor antagonist. The IC50 values of MT-1207 for α1A, α1B, α1D, and 5-HT2A are <0.1 nM, 0.15 nM, 1.40 nM, and 0.27 nM, respectively. MT-1207 induces vasodilation, improves baroreflex sensitivity, and reduces heart rate in isolated hearts. MT-1207 lowers blood pressure, protects the heart, brain, and kidneys, improves cognition, delays stroke, reduces mortality, and lowers uric acid without impairing renal function in SHR/2K1C/2K2C models. MT-1207 exhibits high plasma protein binding, resistance to plasma esterases, and NADPH-dependent hepatic metabolism. MT-1207 can be used for research related to hypertension.
