Publication Abstract from PubMed 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 IC(50)=3.1 nM). Optimization of a pyrazoloquinolinone class of Chk1 kinase inhibitors.,Brnardic EJ, Garbaccio RM, Fraley ME, Tasber ES, Steen JT, Arrington KL, Dudkin VY, Hartman GD, Stirdivant SM, Drakas BA, Rickert K, Walsh ES, Hamilton K, Buser CA, Hardwick J, Tao W, Beck SC, Mao X, Lobell RB, Sepp-Lorenzino L, Yan Y, Ikuta M, Munshi SK, Kuo LC, Kreatsoulas C Bioorg Med Chem Lett. 2007 Nov 1;17(21):5989-94.
