AbstractN‐Alkoxycarbonylmaleimides 3 have been prepared and used to convert amino acids to maleimido acids (6–8) in aqueous solution. The carboxyl group of maleimido acids can be activated for amide or peptide synthesis (e.g., in the N‐succinimidyl esters 10); t‐butyl‐based protecting groups can be cleaved without damage to the maleimide moiety. Peptides carrying maleimide groups are accessible either from the maleimido acids (e.g., 11b, 15) or by direct maleoylation (e.g., 16b). The maleoyl group can be cleaved off by successive mild alkaline and acid hydrolysis or by hydrazinolysis. The reactivity of maleimides toward thiol groups suggests the use of maleimido acids and maleoylpeptides for preparing a wide range of conjugates of biochemical interest.

N-(Carboxyalkyl)maleimides are rapid as well as time-dependent inhibitors of prostaglandin endoperoxide synthase (PGHS). The corresponding N-alkylmaleimides were only time-dependent inactivators of PGHS, suggesting that the carboxylate is critical for rapid inhibition. Several N-substituted maleimide analogs containing structural features similar to those of the nonsteroidal anti-inflammatory drug
