Discovery of 4-Aryl-4H-chromenes as a New Series of Apoptosis Inducers Using a Cell- and Caspase-Based High-Throughput Screening Assay. 3. Structure−Activity Relationships of Fused Rings at the 7,8-Positions
摘要:
As a continuation of our efforts to discover and develop the apoptosis-inducing 4-aryl-4H-chromenes as novel anticancer agents, we explored the SAR of fused rings at the 7,8-positions. It was found that a five-member aromatic ring, such as pyrrolo with nitrogen at either the 7- or 9-position, is preferred. A six-member aromatic ring, such as benzo or pyrido, also led to potent compounds. The SAR of the 4-aryl group was found to be similar for chromenes with a fused ring at the 7,8-positions. These compounds were found to inhibit tubulin polymerization, indicating that cyclization of the 7,8-positions into a ring does not change the mechanism of action. Compound 2h was identified to be a highly potent apoptosis inducer with an EC50 of 5 nM and a highly potent inhibitor of cell proliferation with a GI(50) of 8 nM in T47D cells.

The present invention is directed to substituted 4H-chromene and analogs thereof, represented by the general Formula I:
wherein A, B, X, Y, Z and R

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.
