Bioorg Med Chem Lett. 2016 Nov 1;26(21):5304-5307. doi: 10.1016/j.bmcl.2016.09.039. Epub 2016 Sep 15.

Abstract

The efficient assembly of an 18-membered macrocyclic peptide core was realized by a straightforward and convergent approach utilizing ring-closing metathesis of the corresponding linear tetrapeptides as the key transformation. This approach allowed for the facile preparation of a focused library of novel macrocycles that culminated in the discovery of a cyclophilin A inhibitor with a Kd=5.4μM.

Keywords: Cyclophilin; Macrocycle; Peptidyl-prolyl isomerases; Ring-closing metathesis.
