Biological Activity: HCGRP-(8-37) (Human α-CGRP (8-37)) is a fragment of human calcitonin gene-related peptide (hCGRP) and an antagonist of the CGRP receptor, with an IC50 of 32.1 pM against the CGRP receptor. HCGRP-(8-37) blocks adenylate cyclase activation induced by CGRP receptor ligands and attenuates vascular responses triggered by CGRP. HCGRP-(8-37) reduces capsaicin-induced vasodilation in porcine nasal mucosa and superficial skin. HCGRP-(8-37) serves as a research tool to distinguish effects mediated by CGRP or calcitonin receptors, and to investigate CGRP-induced vascular effects[1][2].
