130-83-6
Chemical Structure
Azapetine phosphate
- No. CAS: 130-83-6
- Formula:C17H20NO4P
- Molecular Weight:333.32
InChIKey: SRNXLNNBIYZIHB-UHFFFAOYSA-N
SMILES: O=P(O)(O)O.C=CCN1CC2=C(C3=C(C1)C=CC=C3)C=CC=C2
Biological Activity: Azapetine phosphate is an antagonist of α1-adrenoceptor, with an IC50 of 0.205 μM at rat α1-adrenoceptor and an IC50 of 1.3 μM at rat α2-adrenoceptor, and exhibits higher selectivity for α1-adrenoceptor than for α2-adrenoceptor. Azapetine phosphate functionally blocks postsynaptic α1-adrenoceptors, and at higher concentrations, it blocks presynaptic α2-adrenoceptors, central α-adrenoceptors, and H2 histamine receptors. Azapetine phosphate is used in related research on hypotension[1][2][3][4].
