Telcagepant structure

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. Leading supplier of anticancer chemical reagents and kinase inhibitors Telcagepant (MK-0974) is a novel calcitonin gene-related peptide (CGRP) receptor antagonist currently undergoing clinical trials for migraine (). MK-0974 is currently being studied in phase III clinical trials. Telcagepant 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 migraine pain.

Telcagepant has non-linear pharmacokinetics after oral doses with greater than dose-proportional increases in AUC 0–∞. The non-linear pharmacokinetics is probably a result of saturation or inhibition of first-pass metabolism.

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. Telcagepant 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 migraine pain. 781649-09-0 - CGDZXLJGHVKVIE-DNVCBOLYSA-N - Telcagepant [USAN:INN] - Similar structures search, synonyms, formulas, resource links, and other chemical information. 953077-35-5 - VESUVMGLUABQCA-LEVQAPRMSA-M - Telcagepant potassium [USAN] - Similar structures search, synonyms, formulas, resource links, and other chemical information.

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. The availability of high-affinity, non-peptide antagonists opens the way for trials of these compounds in other conditions where CGRP antagonism might be useful, such as septic shock and inhibition Overexpression of hRAMP1 increases CGRP signalling by changing the maximal response or ligand sensitivity, depending on tissue type. Furthermore, telcagepant inhibited transgenic hRAMP1 CGRP receptors, but the degree of inhibition suggests that the transgenic mice are only partially humanized or bot … Calcitonin gene-related peptide (CGRP) is a potent neuropeptide whose agonist interaction with the CGRP receptor (CGRP-R) in the periphery promotes vasodilation, neurogenic inflammation and trigeminovascular sensory activation.
