Non-steroidal anti-inflammatory dmgs

Benzoyl-2,3-dihydro-lH-pyrrolizine-l-cai boxylic acid (ketorolac, L ) and 2-(3-benzoyl-phenyl)propionic acid (ketoprofen, L ) ai e biologically activ ligands used in medicine as non-steroidal anti-inflammatory dmgs. 

Whole microbial cells as well as microbially derived enzymes have played a significant role in the production of novel antibiotics. The potential of microorganisms as chemical catalysts, however, was first fully realized in the synthesis of industrially important steroids. These reactions have assumed increasing importance following the discovery that certain steroids such as hydrocortisone have anti-inflammatory activity, whilst derivatives of the steroidal sex hormones are nsefiil as oral contraceptive agents. More recently, chiral inversion of non-steroidal anti-inflammatory dmgs (NS AIDs) has been demonstrated. 

The hydrocarboxylation of styrene (Scheme 5.12) and styrene derivatives results in the formation of arylpropionic acids. Members of the a-arylpropionic acid family are potent non-steroidal anti-inflammatory dmgs (Ibuprofen, Naproxen etc.), therefore a direct and simple route to such compounds is of considerable industrial interest. In fact, there are several patents describing the production of a-arylpropionic acids by hydroxycarbonylation [51,53] (several more listed in [52]). The carbonylation of styrene itself serves as a useful test reaction in order to learn the properties of new catalytic systems, such as activity, selectivity to acids, regioselectivity (1/b ratio) and enantioselectivity (e.e.) in the branched product. In aqueous or in aqueous/organic biphasic systems complexes of palladium were studied exclusively, and the results are summarized in Table 5.2.

With ageing, there is also reduced gastrointestinal blood flow, which can further delay absorption of drugs from the gastrointestinal tract. Alteration in absorption can also make older people more vulnerable to the ulcerogenic effects of some drugs, for example non-steroidal anti-inflammatory dmgs.

As proof of principle, there are several reports of studies in rodents where the object has been to characterise the toxic effects of specific chemicals on the liver or kidneys. Distinct protein patterns have been associated with exposure to peroxisome proliferators activated receptor (PPAR) agonists and non-steroidal anti-inflammatory dmgs that can be used to screen new chemical entities for activity (Anderson et ak, 1996 Eberini et ak, 1999). Proteomics identified the relationship between changes in the expression of a...

Substitution of isosteric components can alter the activity of a compound. For example, one of the first non-steroidal anti-inflammatory (NSAID) compounds produced was mefenamic acid. Its stmcture derives from that of salicylic add, the first non-steroidal anti-inflammatory dmg. First there is an isosteric substitution of NH2 for OH in salicylic add (Fig. 9.2), which causes loss of antiinflammatory activity. Then a dimethylbenzene group is added to the NH2 group as a substituent to produce the...
