Telcagepant Revisited January 25, 2017 Uncategorized Comments: 0. It's only fair to share Telcagepant, PDF | Synthetic studies connected with the synthesis of telcagepant via the corresponding achiral part III and chiral part IV will be discussed. The | Find, read and cite all the research you Disclosed is an efficient synthesis for the manufacture of the caprolactam intermediate (3R,6S)-3-amino-6-(2,3-difluorophenyl)-1-(2,2,2-trifluoroethyl) azepan-2-one: Formula and salts thereof, and an efficient preparation of telcagepant using the caprolactam intermediate. 2006-10-26. 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.

Jahre (Archiv) 2010 Isolating only three intermediates, the overall yield of this cost-effective synthesis was up to 27%. This environmentally responsible synthesis contains all of the elements required for a manufacturing process and prepares telcagepant (1) with the high quality required for pharmaceutical use.

of Merck Rahway disclose their efforts towards an improved multikilogram synthesis of telcagepant, a CGRP receptor antagonist for the treatment of migraines ( J. Org. Chem. 2010, 75, 7829−7841). The route described in the report is an example of a synthetic target driving the discovery of new chemistries. Telcagepant (MK-0974) is an orally active calcitonin gene-related peptide (CGRP) receptor antagonist with Kis of 0.77 nM and 1.2 nM for human and rhesus CGRP receptors, respectively.

The key to the success of this organocatalytic transformation was the identification of a dual acid cocatalyst system, which allowed striking a balance of the 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.
