125I-Bolton-Hunter-substance P (125I-BH-SP) binding properties of three novel classes of neurokinin-1 (NK-1) receptor antagonists were investigated in tissues derived from humans, guinea pigs, and rats. 125I-BH-SP was shown to bind to a single class of binding sites, with similar dissociation
B R Venepalli et al.
Journal of medicinal chemistry, 35(2), 374-378 (1992-01-24)
Several heterosteroids containing a dihydroethisterone skeleton were prepared and shown to displace substance P in a receptor binding assay. Further biochemical (kinetic and Scatchard analyses) and pharmacological evaluation (substance P-induced plasma extravasation and salivation in the rat) of a representative
