  水溶液中的肽合成。一、对二烷基磺基苯酚作为水溶性偶联剂的应用

  摘要：

  发现(对羟基苯基)二甲基锍甲基硫酸盐(HODMSP·MeSO4-)是一种优良的偶联剂，具有水溶性和高反应性；在反应性、产品纯度和外消旋化方面，它与通常的活性酯一样令人满意。HODMSP·MeSO4-活性酯法的显着优势在于，当反应混合物的pH值得到控制时，双功能残基如Arg、Lys、Cys和Tyr可以被选择性地酰化。通过这种新的活性酯方法合成了软体动物神经肽 FMRFamide（Phe-Met-Arg-Phe-NH2），以评估该方法在涉及肽合成的进一步应用中的应用。

  Wewakazole B is a novel cyclodecapeptide with highly potent cytotoxic activity isolated from a sample of M. producens collected from the Red Sea. It contains nine common and three modified amino acid residues. The first total synthesis of Wewakazole B was successfully achieved on a gram scale, unambiguously confirming its structure. Notable features include the careful choice of amino acid-protecting

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

  日期：——

  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。
• Influence of solvent viscosity on the rate of hydrolysis of dipeptides by carboxypeptidase Y

  日期：2004.5

  The influence of solvent viscosity on the rate of enzymatic hydrolysis of a series of dipeptides (Z-Phe-Gly, Z-Phe-Sar, Z-Phe-Ala, Z-Phe-NMeAla, Z-Phe-Aib and Z-Phe-Pro) by carboxypeptidase Y was investigated. The effect of solvent viscosity on the enzymatic hydrolysis revealed that whereas all kcat values decreased with viscosity, those of the N-alkyl peptides decreased more than those of the N-H

  溶剂粘度对一系列二肽（Z-Phe-Gly，Z-Phe-Sar，Z-Phe-Ala，Z-Phe-NMeAla，Z-Phe-Aib和Z-Phe的酶水解速率的影响） （-Pro）通过羧肽酶Y进行了研究。溶剂粘度对酶促水解的影响表明，尽管所有的k cat值均随粘度降低，但N-烷基肽的降幅比N -H肽的降幅更大。动力学行为暗示了涉及酶的构象变化的“诱导适应”过程。版权所有©2004 John Wiley＆Sons，Ltd.
• Relationship between the Hydrophobicity of Dipeptides and the Michaelis–Menten Constant<i>K</i>_mof Their Hydrolysis by Carboxypeptidase-Y and Carboxypeptidase-A
  作者：Yoshifumi Kanosue、Satoshi Kojima、Yoshikazu Hiraga、Katsuo Ohkata

  DOI：10.1246/bcsj.77.1187

  日期：2004.6

  The enzymatic hydrolysis of dipeptides by carboxypeptidase-Y and carboxypeptidase-A was investigated. In the enzymatic hydrolysis of the dipeptides, a good linear relationship (r = 0.997 and 0.999) was found between the Michaelis–Menten constant (Km) and the hydrophobicity of the substrates evaluated from relative elution volume in reversed-phase HPLC. The correlation suggests that the hydrophobicity of the C-terminal amino acid is a major factor in governing the stability of the enzyme–substrate complex. The difference in the slope of the linear-regression lines seems to reflect the degree of relative hydrophobicity of the binding pockets in carboxypeptidase-Y and carboxypeptidase-A.

  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。

  Open chain Cbz‐L‐aa1‐L‐Pro‐Bt (Bt=benzotriazole) sequences were converted into either the corresponding trans‐ or cis‐fused 2,5‐diketopiperazines (DKPs) depending on the reaction conditions. Thermodynamic tandem cyclization/epimerization afforded selectively the corresponding trans‐DKPs (69–75 %). Complementarily, tandem deprotection/cyclization led to the cis‐DKPs (65–72 %). A representative set of
