Structure-Based Design of (5-Arylamino-2H-pyrazol-3-yl)-biphenyl-2‘,4‘-diols as Novel and Potent Human CHK1 Inhibitors
摘要:
The cocrystal structure of a library hit was used to design a novel series of CHK1 inhibitors. The new series retained the critical hydrogen-bonding groups of the resorcinol moiety for binding but lacked the phenolic anilide moiety. The newly designed compounds exhibited similar enzymatic activity, while demonstrating increased cellular potency. Compound 10c, showing no single agent effect, potentiated the anti prol iferati ve effect of Gemcitabine in both prostate and breast cancer cell lines.
Described herein are aminopyrazole compounds of formula I:
wherein R
1
, R
2
, L and Ar are as defined in the specification. Such compounds are capable of modulating the activity of a checkpoint kinase and methods for utilizing such modulation to treat cell proliferative disorders. Also described are pharmaceutical compositions containing such compounds. Also described are the therapeutic or prophylactic use of such compounds and compositions, and methods of treating cancer as well as other diseases associated with unwanted cellular proliferation, by administering effective amounts of such compounds in combination with anti-neoplastic agents.
