  Influence of 4- or 5-substituents on the pyrrolidine ring of 5-[1-(2-methoxymethylpyrrolidinyl)sulfonyl]isatin derivatives on their inhibitory activities towards caspases-3 and -7

  摘要：

  A series of new 4- or 5-substituted pyrrolidine derivatives of 5-[1-(2-methoxymethylpyrrolidinyl)sulfonyl]isatin bearing additional n-butyl or 4-fluorobutyl groups at the isatin nitrogen were prepared and their inhibitory activities have been tested against caspases-3 and -7, which are known to participate in the execution of the programmed cell death, called apoptosis. Several analogues fluorinated at the 4-position of the pyrrolidine ring were also synthesized since such inhibitors might be developed as F-18-radiotracers for molecular imaging of activated caspases in vivo by PET. Enantiomerically pure diastereomeric 4-fluoropyrrolidinyl derivatives inhibited the enzymes in the nanomolar scale, i.e.100-1000 times more efficient than the corresponding 4-methoxy analogues. The 4,4-difluorinated compound showed the best result with IC50 = 362 nM and 178 nM for the aforementioned caspases. In contrast, the 4-methoxy and 4-trifluoromethyl analogues exhibited less inhibition potencies for the enzymes in the mu M scale, whereas all 4-OPEG(4) (PEG(4) = tetraethyleneglycol) and 5-methoxymethyl derivatives were inactive.
