Discovery and structure–activity relationship of N-phenyl-1H-pyrazolo[3,4-b]quinolin-4-amines as a new series of potent apoptosis inducers
摘要:
We report the discovery and SAR study of a series of N-phenyl-1H-pyrazolo[3,4-b]quinolin-4-amines as potent inducers of apoptosis. N-(3-Acetylphenyl)-2,3-dihydro-1H-cyclopenta[b]quinolin-9-amine (2) was discovered through our cell- and caspase-based HTS assays as an inducer of apoptosis. Compound 2 is active against cancer cells derived from several human solid tumors, with EC50 values ranging from 400 to 700 nM. SAR study of hit 2 led to the discovery of N-phenyl-1H-pyrazolo[3,4-b]quinolin-4-amines as a novel series of potent apoptosis inducers, with 1,3-dimethyl-N-(4-propionylphenyl)-1H-pyrazolo[3,4-b]quinotin-amine (6b) having EC50 values ranging from 30 to 70 nM in cancer cells. These compounds also demonstrated potent activity in the cell growth inhibition assay, with GI(50) values of 16-42 nM for compound 6b. (C) 2007 Elsevier Ltd. All rights reserved.

The present invention is directed to substituted N-aryl-1H-pyrazolo[3,4-b]quinolin-4-amines and analogs thereof, represented by the general Formula (I): wherein Q, Y, Z, R4-R7, X and Ar are defined herein. The present invention also relates to the discovery that compounds having Formula (I) are activators of caspases and inducers of apoptosis. Therefore, the activators of caspases and inducers of apoptosis of this invention can be used to induce cell death in a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.
