  摘要：

  制备了两个新的基于APP底物的羟乙烯等聚体（AT和VI），显示它们的二肽共轭物不抑制γ-分泌酶介导的Abeta1-40或Abeta1-42的形成。FG等排物和脱羟基羟乙烯等排物也得到非活性化合物。相反，许多含有完整的底物无关的Phe-Phe（FF）羟乙烯等排物的化合物被证明是有效的抑制剂（ED（50）= 14-732 nM）。这些结果表明，控制γ-分泌酶抑制剂基于底物设计的因素比最初想像的要复杂。

  A general method for preparing specific inhibitors of virus-specified proteases is disclosed. The inhibitors comprise a halomethyl ketone or methyl ketone moiety covalently linked to a peptide sequence of three, four or five amino acids or amino acid residues, which peptide sequence corresponds to an amino acid sequence found adjacent to and upstream of a cleavage site recognized by a virus-specified protease.

• Synthesis of peptide chloromethyl ketones and examination of their inhibitory effects on human spleen fibrinolytic proteinase(SFP) and human leukocyte elastase(LE).

  日期：——

  Various substrate-derived chloromethyl ketones were synthesized by a conventional method for the purpose of obtaining specific and potent irreversible inhibitors for human spleen fibrinolytic proteinase (SFP) and human leukocyte elastase (LE) in order to compare the properties of SFP with those of LE. It was found that Boc-Ala-Tyr-Leu-Val-CH2Cl among the peptide chloromethyl ketones exhibited the most effective and specific inhibition of SFP and LE. The two enzymes were inhibited by peptide chloromethyl ketones having a Val residue at the C-terminus in a similar manner, demonstrating a similarity between SFP and LE.
