The antagonists olcegepant (BIBN4096BS) and telcagepant (MK-0974) are effective drugs in clinical trials for treatment of acute migraine ( Figure 2) [58], and molecular details about their binding and receptor selectivity will guide the development of future molecules.Olcegepant and telcagepant were developed by a classical medicinal chemistry approach following elegant structure-activity

Both drugs act by blocking Telcagepant is rapidly absorbed and plasma concentrations decrease biphasic way, with a terminal half-life of about 6 h. 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. The cocrystal structure of the heterodimer GPCR extracellular domain complex of the CGRP receptor (CLR and RAMP1) has been determined in an apo form and with two different antagonists olcegepant and telcagepant (ter Haar et al., 2010).

Telcagepant (MK-0974) displays saturable binding to SK-N-MC membranes with a K D of 1.9 nM and B max of 479 fmol/mg protein. Telcagepant (MK-0974) also displays saturable binding to rhesus cerebellum homogenate with a K D of 1.3 nM and B max of 20 fmol/mg. MCE has not independently confirmed the accuracy of these methods.

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

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. This process is implicated in the cause of migraine headaches, and CGRP- … Examples of structuralism differ based on the field they are associated with. Structuralism is a school of thought in linguistics, psychology and anthropology.

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.
