  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.

Palladium-catalysed N-allylation starting from optically active proline and prolinol derivatives, as well as from (2S,5S)-2,5-dimethoxymethylpyrrolidine, gave various allylamines bearing trisubstituted olefin moieties.

  (2S,4R)-trans-4-Hydroxy-L-proline has been used as thechiral-pool source in the efficient syntheses of optically active protected 4-hydroxyprolinols. After N-acyl protection andester formation, the first ether moiety was introduced maintaining the chiral centre adjacent to the ester. Then, reduction of the ester delivered the corresponding carbinol, which had to be alkylated selectively to avoid side

  During a program directed at selective NK1 receptor antagonists, we serendipitously discovered an NK1 receptor ligand with additional affinity for the NK3 receptor. Recognising an opportunity for a drug discovery program aiming for dual NK1/NK3 receptor antagonists, we prepared a series of analogues from a novel, versatile building block. From this series emerged compounds with high and balanced affinities
