Selective COX-2 inhibitors. Part 2: Synthesis and biological evaluation of 4-benzylideneamino- and 4-phenyliminomethyl-benzenesulfonamides
摘要:
Two series of 4-benzylideneamino- and 4-phenyliminomethyl-benzenesulfonamide derivatives were designed and synthesized for the evaluation as selective cyclooxygenase-2 (COX-2) inhibitors in a cellular assay using human whole blood (HWB). Extensive structure-activity relationships (SAR) were studied within these series. Several compounds were found to be novel and selective COX-2 inhibitors. Among them, the most potent and selective was 4-(3-carboxy-4-hydroxy-benzylideneamino)benzenesulfonamide (20, LA2135), (IC50'S for COX- 1: 85.13 mu M; COX-2: 0.74 mu M; SI: 114.5), being more active COX-2 selective than celecoxib.

A series of Schiff bases was prepared by reaction of sulfanilamide with substituted benzene- and heterocyclic aldehydes. The compounds were characterized by standard procedures, and were assayed as inhibitors of the zinc enzyme carbonic anhydrase (CA). The new compounds act as inhibitors towards isozymes CA I and II (cytosolic) and CA IV (membrane-bound), and possess an equally high affinity for the last two, in contrast to classical inhibitors which are 17-33 times less effective against CA IV. This is the first evidence of high-affinity CA IV inhibitors, and might lead to the development of low molecular weight CA IV isozyme-specific derivatives.

This invention describes a series of methods and compositions for prevention and treatment of diseases such as cancer. One aspect of the invention describes small molecule-based drugs that can be used to bind to death receptors TRAIL-R1/DR4 and/or TRAIL-R2/DR5 and induce apoptosis in cancer cells, while sparing normal cells. The invention also describes TRAIL Death Receptor Agonists/Activators (DRAs) and their uses, such as the induction of apoptosis through caspase-8 and caspase-3 activation. The present invention also describes the methods of treating cancers, such as breast, prostate, colon, pancreatic, ovarian, lung, and brain cancers, leukemia, lymphoma, multiple myeloma, and mesothelioma, using DRAs either as single-agent treatments, or in combination with other therapies.
