  To develop a potent and specific collagenas inhibitor, a series of tetrapheptidyl hydroxamic acids were synthesized, based on the previous findings with tripeptidyl derivatives (Chem. Pharm. Bull., 38, 1007-1011, 1990). Among the series of tetrapeptidyl derivatives synthesized, R-Gly-Pro-Leu-Ala-NHOH and R-Gly-Pro-D-Leu-D-Ala-NHOH were found to be highly specific and potent inhibitors against vertebrate collagenase with an IC50 of 10-6M order, where R stands for Boc or acyl group. Analysis of their structure-activity relationships showed a characteristic feature of the substrate-binding site of collagenase as follows : 1) the S1 subsite forms a shallow hydrophobic pocket, although glycine residue corresponds to the subsite of the natural collagen substrate : 2) the S2 substite constitutes a bulky pocket with less requirement for hydrophobicity : 3) the S3 subsitte preferentially accommodates Pro residue : and 4) the accommodation of the P4-P1 substites of peptidyl collagenase inhibitor to the S4-S1 substites is required to form a tight binding of its hydroxamic acid moiety to the zinc ion at the catalytic site of the enzyme. The introduction of an enantiometric dipeptide unit, D-Leu-D-Ala, to the P2-P1 subsites demonstrated an increased binding capacity to the extended S4-S1 subsites of collagenase, thus providing proteinase-resistant inhibitor.

  为了开发一种有效且特异性强的胶原酶抑制剂，研究人员合成了一系列四肽羟胺酸，这基于之前关于三肽衍生物的研究结果（Chem. Pharm. Bull., 38, 1007-1011, 1990）。在合成的四肽衍生物系列中，R-Gly-Pro-Leu-Ala-NHOH 和 R-Gly-Pro-D-Leu-D-Ala-NHOH 被发现对脊椎动物胶原酶具有高度特异性和有效抑制作用，IC50 约为10^-6M，其中 R 代表 Boc 或酰基。对其结构-活性关系的分析显示了胶原酶底物结合位点的几个特征：1）S1 亚位点形成一个浅的疏水口袋，虽然甘氨酸残基对应于天然胶原底物的亚位点；2）S2 亚位点形成一个体积较大的口袋，对疏水性的需求较低；3）S3 亚位点优先容纳脯氨酸残基；4）肽类胶原酶抑制剂的 P4-P1 亚位点与 S4-S1 亚位点的结合是形成其羟胺酸基团与酶催化位点的锌离子紧密结合所必需的。将一个对映体二肽单元 D-Leu-D-Ala 引入到 P2-P1 亚位点中，显示出与胶原酶扩展的 S4-S1 亚位点的结合能力增加，从而提供了耐蛋白酶的抑制剂。
• Preparation of bifunctional isocyanate hydroxamate linkers: synthesis of carbamate and urea tethered polyhydroxamic acid chelators

  Two novel bifunctional N-methylhydroxamate-isocyanate linkers 20 and 21 were prepared in good yield and high purity from the corresponding amine salts using a biphasic reaction with phosgene. The facile ring opening reaction of N-Boc lactams using the anion of O-benzylhydroxylamine gave the protected amino hydroxamates 6a and 6c in good yields. The selective methylation of the hydroxamate nitrogen in the presence of the N-Boc group in these intermediates could be readily accomplished. The utility of the linkers was clearly demonstrated by the synthesis of the carbamate-tethered trishydroxamic acid 27 and the urea-tethered 29. (C) 2012 Elsevier Ltd. All rights reserved.
