Discovery of Small Molecule RIP1 Kinase Inhibitors for the Treatment of Pathologies Associated with Necroptosis
摘要:
Potent inhibitors of RIP1 kinase from three distinct series, 1-aminoisoquinolines, pyrrolo[2,3-b]pyridines, and furo[2,3-d]pyrimidines, all of the type II class recognizing a DLG-out inactive conformation, were identified from screening of our in-house kinase focused sets. An exemplar from the furo[2,3-d]pyrimidine series showed a dose proportional response in protection from hypothermia in a mouse model of TNF alpha induced lethal shock.
Derivatives of pyrrolo[2,3-b]pyridine which are useful as SGK-1 kinase inhibitors are described herein. The invention described herein also describes pharmaceutical compositions containing derivatives of pyrrolo[2,3-b]pyridine and methods of using pyrrolo[2,3-b]pyridine derivatives and pharmaceutical compositions thereof in the treatment of diseases mediated by SGK-1.

The lead serum and glucocorticoid-related kinase 1 (SGK1) inhibitors 4-(5-phenyl-1H-pyrrolo[2,3-b]pyridin-3-yl)benzoic acid (1) and 4-[5-(2-naphthalenyl)-1H-pyrrolo[2,3-b] pyridin-3-yl]phenyl}acetic acid (2) suffer from low DNAUC values in rat, due in part to formation and excretion of glucuronic acid conjugates. These PK/glucuronidation issues were addressed either by incorporating a substituent on the 3-phenyl ring ortho to the key carboxylate functionality of 1 or by substituting on the group in between the carboxylate and phenyl ring of 2. Three of these analogs have been identified as having good SGK1 inhibition potency and have DNAUC values suitable for in vivo testing. (C) 2009 Elsevier Ltd. All rights reserved.
