A potent, selective and orally available CGRP receptor antagonist for the prevention of migraine. Migraine.

MK-0974(Telcagepant) is a highly potent, selective, and orally bioavailable CGRP receptor antagonist with Ki values of 0.77 nM and 1.2 nM for human and rhesus CGRP receptors respectively; displays >1500-fold lower affinity for the canine and rat receptors

MK-3207 is a potent and orally bioavailable CGRP receptor antagonist (IC50= 0.12 nM; Ki value= 0.024 nM); highly selective versus human AM1, AM2, CTR, and AMY3.

Olcegepant hydrochloride is the first potent and selective non-peptide antagonist of the calcitonin gene-related peptide 1 (CGRP1) receptor with IC50 of 0.03 nM and with a Ki of 14.4 pM for human CGRP.

Olcegepant(BIBN 4096; BIBN 4096BS) is the first potent and selective non-peptide antagonist of the calcitonin gene-related peptide 1 (CGRP1) receptor(IC50= 0.03 nM).

Adrenomedullin (AM) (22-52), human (22-52-Adrenomedullin human) TFA, an NH2 terminal truncated adrenomedullin analogue, is an adrenomedullin receptor antagonist. Adrenomedullin (AM) (22-52), human also antagonizes the calcitonin generelated peptide (CGRP) receptor in the hindlimb vascular bed of the cat.

PHM-27 (human) is a human prepro-vasoactive intestinal polypeptide (27 amino acid). PHM-27 (human) is a potent the human calcitonin receptor agonist with an EC50 of 11 nM. PHM-27 (human) efficiently enhances glucose-induced insulin secretion from beta cells by an autocrine mechanism.

Adrenomedullin (16-31), human TFA is amino acid residues 16-31 fragment of human adrenomedullin (hADM). Adrenomedullin has appreciable affinity for the CGRP1 receptor. Adrenomedullin (16-31), human TFA possesses pressor activity in the systemic vascular bed of the rat, but not the cat.

Calcitonin human is an endogenous calcitonin receptor agonist.Calcitonin human lowers systemic blood calcium levels and inhibits bone resorption.
