An NSAID. Circumvents MRP-mediated multidrug resistance. Significantly increases the cytotoxicity of the anthracyclines (doxorubicin, daunorubicin and epirubicin), as well as teniposide, VP-16 and vincristine.
Cataract is the leading cause of blindness worldwide. Epidemiological studies revealed up to a fivefold increased prevalence of cataracts in diabetic subjects. Metabolomics is nowadays frequently implemented to understand pathophysiological processes responsible for disease occurrence and progression. It has also

Human serum albumins modified by covalently bound tolmetin or zomepirac were synthesized as models for similar products formed in vivo from acyl glucuronides. Activated esters of both drugs were prepared with 1-ethyl-3-(3-dimethylaminopropyl)-carbodi-imide, and then allowed to react with human serum

Carboxylate drugs usually form acyl glucuronide conjugates as major metabolites. These electrophilic metabolites are reactive, capable of undergoing hydrolysis, rearrangement, and covalent binding reactions to proteins. The last-mentioned property has the potential to initiate immune and other toxic responses in
Many nonsteroidal anti-inflammatory drugs (NSAIDs) which have antiproliferative activity in colon cancer cells are carboxylate compounds forming acyl glucuronide metabolites. Acyl glucuronides are potentially reactive, able to hydrolyse, rearrange into isomers, and covalently modify proteins under physiological conditions. This study
Journal of pharmacological and toxicological methods, 36(3), 131-136 (1996-11-01)
Acyl glucuronide conjugates of acidic drugs are chemically unstable metabolites, able to undergo a number of reactions including covalent binding interactions with proteins. The question of whether any toxicological or immunological responses result from such covalent modification of native proteins
Protein-based drug transporters are expressed in Sf9 cells. Understanding the specific mechanisms of tumor cell transporters is an essential aspect of chemotherapeutic drug design.
