Optimization of a pyrazoloquinolinone class of Chk1 kinase inhibitors
摘要:
The development of 2,5-dihydro-4H-pyrazolo[4,3-c]quinolin-4-ones as inhibitors of Chk1 kinase is described. Introduction of a fused ring at the C7/C8 positions of the pyrazoloquinolinone provided an increase in potency while guidance from overlapping inhibitor bound Chk1 X-ray crystal structures contributed to the discovery of a potent and solubilizing propyl amine moiety in compound 52 (Chk1 IC50 = 3.1 nM).

receptor contain a carboxylic acid, which we believe to be detrimental to penetration of the blood-brain barrier. By consideration of a pharmacophore, novel antagonists at this site have been designed in which the anionic functionality is a vinylogous acid, in the form of a 4-hydroxyquinolin-2(1H)-one. In this series, a 3-substituent is necessary for binding, and correct manipulation of this group leads
