We also report the structures of CLR/RAMP1 in complex with the clinical receptor antagonists olcegepant (BIBN4096BS) and telcagepant (MK0974). Olcegepant (BIBN-4096) is a potent and selective non-peptide antagonist of the calcitonin gene-related peptide 1 (CGRP1) receptor with IC50 of 0.03 nM and Ki of 14.4 pM for human CGRP. - Mechanism of Action & Protocol. Telcagepant (MK0974) is one of several calcitonin-gene-related peptide antagonists in development as a potential treatment for acute migraine attacks and is the first orally available drug in this For telcagepant, DILIsym predicted hepatotoxicity at clinical doses ≥ 175 mg BID, consistent with results from a phase 2 study for the acute treatment for migraine in which 13 of 638 people experienced ALT elevations ≥ 3× ULN, including 1.9% (5/258) of those treated with telcagepant 140 mg BID and 3.2% (8/253) of those treated with telcagepant 280 mg BID, compared with 0 of 127 people Telcagepant (MK-0974, Merck & Co., Inc.), an oral calcitonin gene-related peptide (CGRP) antagonist, is effective in treating acute migraine headache. Although CGRP receptor antagonists seem devoid of direct vasoconstrictor activity, animal research suggests a role for CGRP in nitroglycerin (NTG) induced vasodilation. Telcagepant for Prevention of Menstrually Related Migraine in Female Participants With Episodic Migraine (MK-0974-065) The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Structure and pharmacology of telcagepant The CGRP family of receptors mediate their physiological eﬀ ects through the joining of CLR and RAMP1, which are needed for G-protein signal transduction via the receptor component-protein.15 Initial high-throughput screening resulted in identiﬁ cation of a potent and orally bioavailable Importance of the field: Calcitonin gene-related peptide (CGRP) receptor antagonists have recently come to attention with the development of olcegepant and telcagepant for the treatment of migraine.
159 Starting from truncated analogs of olcegepant, they identified 165 (Fig. 36, K i = 280 nM) and optimized this flexible lead structure by incorporating conformational constraints. Telcagepant, also known as MK0974, is a calcitonin gene-related peptide receptor antagonist under development for the acute treatment and prevention of migraine. MedKoo Biosciences, Inc.

IC 50 & Target Ki: 0.77 nM (human CGRP), 1.2 nM (rhesus CGRP) Telcagepant blocks the binding of CGRP to receptors within the areas of the central and peripheral nervous system that are important for the transmission of migraine pain and thereby is believed to inhibit the transmission of pain signals that lead to migraine headaches.

CGRP and its receptors are found in areas of the central and peripheral nervous system that are important for the transmission of migraine pain. MK-0974 (Telcagepant) Chemical Structure CAS NO. 781649-09-0 MK-0974 (Telcagepant) is a potent and selective antagonist of the human and rhesus CGRP receptors. The structure reveals a slightly different topology at the hydrogen bond donor-acceptor site (Figure 5D), where the azabenzimidazolone ring system of telcagepant forms an additional weak hydrogen bond with the backbone carbonyl of CLR Thr122. As in olcegepant, the piperidyl moiety forms an edge-to-face stack with CLR Trp72.
