Theoretical investigation of the molecular structure and molecular docking of Imidazo [4,5-b] pyridiner: Telcagepant — en kalcitoningen-relaterad peptidreceptorantagonist som var i kliniska prövningar som ett botemedel Telcagepant has been investigated for the treatment of Migraine. It is an antagonist of the receptor for calcitonin gene-related peptide (CGRP), a primary neuropeptide involved in the pathophysiology of migraine. CGRP and its receptors are found in areas of the central and peripheral nervous system that are important for the transmission of Telcagepant. Telcagepant ( INN) (code name MK-0974) is a calcitonin gene-related peptide receptor antagonist which was an investigational drug for the acute treatment and prevention of migraine, developed by Merck & Co.. In the acute treatment of migraine, it was found to have equal potency to rizatriptan and zolmitriptan. 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.;IC50 value: 0.77/1.2 nM(Human and rhesus CGRP) [1];Target: CGRP receptor;In vitro: MK-0974 is a potent antagonist of the human (K(i) = 0.77 nM) and rhesus (K(i) = 1.2 nM) CGRP receptors but displays >1500-fold lower affinity for the canine English: Chemical structure of telcagepant—an antimigraine drug.

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.
