Title:

Scaffold hopping towards potent and selective JAK3 inhibitors: discovery of novel C-5 substituted pyrrolopyrazines.

Bioorg Med Chem Lett. 2014 Nov 1;24(21):4969-75. doi: 10.1016/j.bmcl.2014.09.031., Epub 2014 Sep 21.

Abstract:

The discovery of a novel series of pyrrolopyrazines as JAK inhibitors with comparable enzyme and cellular activity to tofacitinib is described. The series was identified using a scaffold hopping approach aided by structure based drug design using principles of intramolecular hydrogen bonding for conformational restriction and targeting specific pockets for modulating kinase activity.
