Endothelin 10 nM affected neither the affinity nor density of dihydropyridine binding sites. At concentrations of 10(-12)-10(-7) M, endothelin failed to displace bound (+)-[3H]-PN 200/110, (-)-[3H]-D888 and (+)-cis-[3H]-diltiazem. These results suggest that the calcium antagonist binding sites associated with L-type calcium channels are not the primary site of action of endothelin. | Gov't Doc #: | 2538185 | URI: | https://ahro.austin.org.au/austinjspui/handle/1/12465 | Journal: | British journal of pharmacology | URL: | https://pubmed.ncbi.nlm.nih.gov/2538185 | Type: | Journal Article | Subjects: | Animals Binding, Competitive Calcium Channel Blockers.metabolism Calcium Channels Diltiazem.metabolism Endothelins Female In Vitro Techniques Isradipine Oxadiazoles.metabolism Peptides.metabolism.pharmacology Rats Rats, Inbred Strains Receptors, Nicotinic.drug effects Verapamil.analogs & derivatives.metabolism |
