HCGRP-(8-37)
Based on 2 publication(s) in Google Scholar
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.

Biological Activity
CGRP receptor[1]
HCGRP-(8-37) (10 min at 37°C) acts as a CGRP receptor antagonist in rat liver plasma membranes. It inhibits CGRP- and calcitonin-induced adenylate cyclase activation in a dose-dependent manner, but does not affect basal, epinephrine- or glucagon-stimulated activities[1].
HCGRP-(8-37) (60 min at 37°C) binds to calcitonin receptors in LLC-PK1 porcine kidney cells in a dose-dependent manner[1].
HCGRP-(8-37) (15 min at 37°C) acts as a calcitonin receptor agonist in LLC-PK1 porcine kidney cells, which dose-dependently stimulates cAMP production without antagonizing calcitonin- or CGRP-induced cAMP production[1].
HCGRP-(8-37) potently inhibits CGRP-mediated adenylate cyclase activation in cell-free rat liver plasma membrane preparations[2].

Result:Significantly attenuated capsaicin-evoked increases in nasal vascular conductance and decreases in nasal cavity volume.
Significantly reduced capsaicin-evoked superficial skin blood flow when calculated as area under the curve (AUC); capsaicin-induced skin peak blood flow remained unchanged (96% of control, not significant), but the duration of the skin response was significantly reduced to 69% of control .
Significantly reduced CGRP-evoked increases in nasal vascular conductance and decreases in nasal cavity volume.
Significantly attenuated CGRP-evoked superficial skin blood flow, with reductions seen in AUC, peak response, and response duration.
