  摘要：

  研究人员研究了 Nα，Nca-二叔丁氧羰基高谷氨酰胺在合成促甲状腺激素释放激素（TRH）类似物中的应用。在含有乙酸的水或二氧六环中，均谷氨酰胺肽形成δ-内酰胺比谷氨酰胺肽形成γ-内酰胺更容易。[pHgu1，Nva2]-TRH 对小鼠戊巴比妥麻醉具有剂量依赖性拮抗活性，但对大鼠脑中的 TRH 受体几乎没有结合活性。

  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.

  from TRH. In spite of this fact, 7 of the 17 analogues (1, 2, 8-10, 16, and 17) have stronger anticataleptic effect than TRH, with negligible or no hormonal potency. The highest CNS activity was achieved when pyroglutamic acid was replaced by pyro-2-aminoadipic acid at the N-terminus [pAad-Leu-Pro-NH2, 1 (RGH 2202), and pAad-Nva-Pro-NH2,2]. A novel synthesis of L-2-aminoadipic acid suitable for large-scale

  通过五氟苯基酯法合成了一系列新的促甲状腺激素释放激素（TRH）类似物，这些类似物是通过进一步修饰我们最有效的中枢神经系统（CNS）在两个末端刺激中性三肽而获得的，并测试了CNS和促甲状腺激素（TSH）释放活动。[Leu2]中的吡咯-2-氨基己二酸，2-氧代咪唑烷-4-羧酸或γ-丁内酯-γ-羧酸取代脯氨酸谷氨酸，脯氨酸由哌啶酸，噻唑烷-4-羧酸或高脯氨酸代替脯氨酸。 -和[Nva2] TRH导致三肽结构上与TRH大不相同。尽管如此，17种类似物中的7种（1、2、8-10、16和17）比TRH具有更强的抗感性作用，激素作用微乎其微或无。当焦谷氨酸在N端被焦-2-氨基己二酸取代时，CNS活性最高[pAad-Leu-Pro-NH2，1（RGH 2202）和pAad-Nva-Pro-NH2,2]。还描述了适用于大规模制备的L-2-氨基己二酸的新颖合成。
