NPC-14695
- CAS No.: 146561-59-3
- Formula:C24H30N2O2
- Molecular Weight:378.51
InChIKey: YTZUOZVKZMXBOP-UHFFFAOYSA-N
SMILES: O=C(C(C1=CC=CC=C1)(C2CCC2)O)CN3CCN(CC3)CC4=CC=CC=C4
Biological Activity: NPC-14695 is a competitive and selective M3 muscarinic receptor antagonist, with a Kd value of 15 nM for guinea pig M3, 60 nM for guinea pig M2, and 25 nM for rabbit M1. NPC-14695 exhibits higher activity towards M3 receptors in bronchial smooth muscle than towards those regulating salivary secretion. NPC-14695 inhibits Carbachol (HY-B1208)-induced contraction of isolated rabbit iris smooth muscle[1][2].
