NSAIDs: Old Drugs Reveal New Anticancer Targets

NSAIDs: Old Drugs Reveal New Anticancer Targets

There is compelling evidence that nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase-2 selective inhibitors have antineoplastic activity, but toxicity from cyclooxygenase (COX) inhibition and the suppression of physiologically important prostaglandins limits their use for cancer chemoprevention. Previous studies as reviewed here suggest that the mechanism for their anticancer prop...

Old Drugs, New Tricks Using Genetically Sensitized Yeast to Reveal Drug Targets

A study in this issue of Cell illustrates the power of applying genomic approaches with model systems to characterize the biological activity of small molecules and to identify their cellular targets, which can clarify the mode of action of human therapeutics.

Non-steroidal anti-inflammatory drugs (NSAIDs) in Alzheimer's disease: old and new mechanisms of action.

Alzheimer's disease (AD) is characterized by cerebral deposits of beta-amyloid (A beta) peptides and neurofibrillary tangles (NFT) which are surrounded by inflammatory cells. Epidemiological studies have shown that prolonged use of non-steroidal anti-inflammatory drugs (NSAIDs) reduces the risk of developing AD and delays the onset of the disease. It has been postulated that some NSAIDs target ...

Sulfa Drugs as Inhibitors of Carbonic Anhydrase: New Targets for the Old Drugs

Sulfa drugs are well-known antibacterial agents containing N-substituted sulfonamide group on para position of aniline ring (NH2RSO2NHR'). In this study 2,4-dichloro-1,3,5-triazine derivatives of sulfa drugs, sulfamerazine (1b), sulfaquinoxaline (2b), sulfadiazine (3b), sulfadimidine (4b), and sulfachloropyrazine (5b) (1a-5a) were synthesized and characterized. Their carbonic anhydrase inhibiti...
