Synthesis and biological evaluation of dialkylsubstituted maleic anhydrides as novel inhibitors of Cdc25 dual specificity phosphatases
摘要:
An efficient synthesis of dialkyl substituted maleic anhydrides 1a-j is described. The inhibitory potential of these original anhydride derivatives was tested toward the three human isoforms A, B and C of dual specific phosphatases Cdc25. A micromolar range inhibition of Cdc25s was observed with the maleic anhydrides bearing simple alkyl side chains longer than C-9, to reach the optimal activity with a C-17 chain length.

the synthesis of natural and unnatural substituted maleicanhydrides based on the Barton radical decarboxylation is described. The radicals, generated by the photolysis of N-hydroxy-2-thiopyridone esters derived from succinic and alkyl acids reacted, respectively, with electron deficient olefin phenyl maleimide by a consecutive two-step radical addition, afforded the corresponding disubstituted maleic
