  Relationship between the Hydrophobicity of Dipeptides and the Michaelis–Menten ConstantK_mof Their Hydrolysis by Carboxypeptidase-Y and Carboxypeptidase-A

  摘要：

  研究了羧肽酶Y和羧肽酶A对二肽的酶解水解作用。在二肽的酶解水解过程中，发现米氏常数（Km）与通过反相高效液相色谱的相对洗脱体积评估的底物疏水性之间存在良好的线性关系（r = 0.997 和 0.999）。这种相关性表明，C端氨基酸的疏水性是影响酶-底物复合体稳定性的主要因素。线性回归线的斜率差异似乎反映了羧肽酶Y和羧肽酶A结合口袋的相对疏水性程度。

• Amino acids and peptides. XXVIII. Synthesis of peptide fragments related to eglin c and studies on the relationship between their structure and effects on human leukocyte elastase, cathepsin G and .ALPHA.-chymotrypsin.

  Various peptide fragments related to eglin c, which consists of 70 amino acid residues, were synthesized by a conventional solution method and their inhibitory effects on leukocyte elastase, cathepsin G and α-chymotrypsin were examined. Among them, H-Arg-Glu-Tyr-Phe-OMe (eglin c 22-25) and H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OMe (eglin c 41-49) inhibited cathepsin G and α-chymotrypsin but not leukocyte elastase, while H-Thr-Asn-Val-Val-OMe (eglin c 60-63) inhibited leukocyte elastase but not cathepsin G or α-chymotrypsin, although eglin c potently inhibited leukocyte elastase, cathepsin G and α-chymotrypsin. These results indicated that the interaction sites of eglin c with leukocyte elastase, cathepsin G and α-chymotrypsin might be different.

• Synthesis and structure of prolinal-containing peptides, and their use as specific inhibitors of prolyl endopeptidases.

  Peptide aldehydes are potent inhibitors of serine and cysteine proteases. In the present work, N-benzyloxycarbonyl (Z) dipeptides containing prolinal at the carboxyl terminus were syntheized as inhibitors of prolyl endopeptidases. Since no aldehyde proton was detected by proton nuclear magnetic resonance (1H-NMR) spectrometry, a cyclic structure was proposed for these peptides. Compounds with a Z-L-X-L-prolinal structure were strong inhibitors of prolyl endopeptidases from the ascidian, Halocynthia roretzi, and Flavobacterium meningosepticum. The potency was in the order of Z-L-Val-L-prolinal≃Z-L-Ile-L-prolinal>Z-L-Phe-L-prolinal>Z-L-Ala-L-prolinal with IC50 values of 10-8-10-6 M order for both enzymes. Conversion of the aldehyde into an alcohol or an acid moiety resulted in a considerable decrease in the inhibitory activity. The diastereomers of Z-L-Phe-L-prolinal were much less inhibitory. This result is not compatible with the reported stereospecifity of the Flavobacterium enzyme for its substrated [T. Yoshimoto, R. Walter and D. Tsuru, J. Biol. Chem., 255, 4786 (1980)]. This implies that the open species binds preferentially to the enzyme active site.

  肽醛是丝氨酸和半胱氨酸蛋白酶的强效抑制剂。在本研究工作中，合成了含羧基末端脯氨醛的N-苄氧羰基（Z）二肽，作为脯氨酰内肽酶的抑制剂。由于通过质子核磁共振（1H-NMR）光谱法未检测到醛质子，因此为这些肽提出了一个环状结构。具有Z-L-X-L-脯氨醛结构的化合物是海鞘Halocynthia roretzi和黄杆菌Flavobacterium meningosepticum的脯氨酰内肽酶的强效抑制剂。其效力顺序为Z-L-Val-L-脯氨醛≈Z-L-Ile-L-脯氨醛>Z-L-Phe-L-脯氨醛>Z-L-Ala-L-脯氨醛，IC50值为10-8-10-6 M，对两种酶均有效。将醛转化为醇或酸部分会导致抑制活性显著降低。Z-L-Phe-L-脯氨醛的差向异构体抑制作用较弱。这一结果与黄杆菌酶对其底物的报道立体特异性不一致。这表明开放型物种优先结合到酶活性位点。

• Dynamic combinatorial libraries of hydrazone-linked pseudo-peptides: dependence of diversity on building block structure and chirality

  Expanding on our earlier building block architecture [(MeO)2CH–Linker–Pro–X–NHNH2 where X = Phe, Cha], we have produced a series of new pseudo-dipeptides [(MeO)2CH–Linker–Pro–X–NHNH2 where X = Val, Leu, Ile, Ala] for use in hydrazone-based dynamic combinatorial libraries (DCLs); reverse order analogues [Phe-Pro and Val-Pro] and two enantio-analogues [Pro-Phe and Pro-Val] were also prepared. The behaviours of these building blocks in DCLs, as single components and in mixtures, were studied systematically using HPLC and mass spectrometry in order to gain insight into the relationship between building block structure and good library diversity. Subtle changes in building block structure lead to significant changes in library distribution and in the ability to produce diverse libraries in mixtures.

  基于我们早期的构建模块架构[(MeO)2CH–Linker–Pro–X–NHNH2，其中X = Phe, Cha]，我们合成了一系列新的伪二肽[(MeO)2CH–Linker–Pro–X–NHNH2，其中X = Val, Leu, Ile, Ala]，用于基于脒的动态组合库（DCLs）；反向顺序类似物[Phe-Pro和Val-Pro]以及两种对映异构类似物[Pro-Phe和Pro-Val]也被制备。我们系统地研究了这些构建模块在DCL中的行为，无论是单独成分还是混合物，都使用了高效液相色谱法和质谱法，以深入了解构建模块结构与良好库多样性之间的关系。构建模块结构的细微变化导致了库分布的显著变化以及在混合物中产生多样性库的能力的变化。
