• 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

  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.

  A novel series of pyrrolidine-containing GPR40 agonists is described as a potential treatment for type 2 diabetes. The initial pyrrolidine hit was modified by moving the position of the carboxylic acid, a key pharmacophore for GPR40. Addition of a 4-cis-CF3 to the pyrrolidine improves the human GPR40 binding K-i and agonist efficacy. After further optimization, the discovery of a minor enantiomeric impurity with agonist activity led to the finding that enantiomers (R,R)-68 and (S,S)-68 have differential effects on the radioligand used for the binding assay, with (R,R)-68 potentiating the radioligand and (S,S)-68 displacing the radioligand. Compound (R,R)-68 activates both G(q)-coupled intracellular Ca2+ flux and G(s)-coupled cAMP accumulation. This signaling bias results in a dual mechanism of action for compound (R,R)-68, demonstrating glucose-dependent insulin and GLP-1 secretion in vitro. In vivo, compound (R,R)-68 significantly lowers plasma glucose levels in mice during an oral glucose challenge, encouraging further development of the series.
