摘要
Fragment-based hit identification coupled with crystallographically enabled structure-based drug design was used to design potent inhibitors of JAK-2. After two iterations from fragment 1, we were able to increase potency by greater than 500-fold to provide sulfonamide 13, a 78-nM JAK-2 inhibitor. (C) 2008 Published by Elsevier Ltd.
