Novel oxazolidinone calcitonin gene-related peptide (CGRP) receptor antagonists for the acute treatment of migraine

Bioorg Med Chem Lett. 2015 Nov 1;25(21):4777-4781. doi: 10.1016/j.bmcl.2015.07.021. Epub 2015 Jul 14.

Abstract

In our efforts to develop CGRP receptor antagonists as backups to MK-3207, 2, we employed a scaffold hopping approach to identify a series of novel oxazolidinone-based compounds. The development of a structurally diverse, potent (20, cAMP+HS IC50=0.67 nM), and selective compound (hERG IC50=19 μM) with favorable rodent pharmacokinetics (F=100%, t1/2=7h) is described. Key to this development was identification of a 3-substituted spirotetrahydropyran ring that afforded a substantial gain in potency (10 to 35-fold).

Keywords: CGRP; Class B GPCR; Migraine; Oxazolidinone; Scaffold hopping.
