  Design, Synthesis, and Tripeptidyl Peptidase II Inhibitory Activity of a Novel Series of (S)-2,3-Dihydro-2-(4-alkyl-1H-imidazol-2-yl)-1H-indoles

  摘要：

  Butabindide, 1, was previously reported as a potent inhibitor (IC50 = 7 nM) of the serine protease enzyme tripeptidyl peptidase II (TPPII), an endogenous protease that degrades cholecystokinin-8 (CCK-8). We found that 1 has some inherent chemical instability, yielding diketopiperazine 2 fairly readily under mimicked physiological conditions. We therefore prepared imidazoles 3, which are void of 1's inherent instability, and have found that our novel analogues maintained comparable TPPII inhibitory activity (e.g.,for 3c, IC50 = 4 nM) as 1.

  Inhibitors of Tripeptidyl Peptidase II. 3. Derivation of Butabindide by Successive Structure Optimizations Leading to a Potential General Approach to Designing Exopeptidase Inhibitors

  摘要：

  The cholecystokinin-8 (CCK-8)-inactivating peptidase is a serine peptidase that has been shown to be a membrane-bound isoform of tripeptidyl peptidase II (EC 3.4.14.10). It cleaves the neurotransmitter CCK-8 sulfate at the Met-Gly bond to give Asp-Tyr(SO(3)H)-Met-OH + GlyTrp-Met-Asp-Phe-NH(2). Starting from Val-Pro-NHBu, a dipeptide of submicromolar affinity that had previously been generated to serve as a lead, successive optimization at P3, P1, and then P2 gave Abu-Pro-NHBu (18, K(i) = 80 nM). Further transformation (by making a benzologue) gave the indoline analogue, butabindide (33) as a reversible inhibitor having nanomolar affinity (Ki = 7 nM). Retrospective analysis suggested the possibility of a general approach to designing exopeptidase inhibitors starting from the structure of the first hydrolysis product. Application of this approach to CCK-8 led to Abu-Phe-NHBu (37), but this only had K(i) = 9.4 mu M. Molecular modeling, to determine the minimum energy conformations and explain the 1000-fold better affinity of butabindide, indicated that 37 cannot access the likely active conformation of butabindide.
