  Total Synthesis of Bleomycin A2 and Related Agents. 1. Synthesis and DNA Binding Properties of the Extended C-Terminus: Tripeptide S, Tetrapeptide S, Pentapeptide S, and Related Agents

  摘要：

  Full details of concise, diastereocontrolled syntheses of 2-5 and their incorporation into tri-, tetra-, and pentapeptide S, the C-terminus of bleomycin Alt are described. The extension of the studies to the synthesis of a complete set of tri- and tetrapeptide S structural analogs 29a,b and 43b-j is detailed, and their DNA binding constants (apparent K-B, calf thymus DNA) and apparent binding site sizes were determined. Consistent with past observations, the studies highlight the fact that the majority of the DNA binding affinity for bleomycin A(2) (1.0 X 10(5) M(-1)) and deglycobleomycin Aa (1.1 x 10(5) M(-1)) is embodied within N-BOC-tripeptide S (0.26 X 10(5) M(-1)). The additional comparisons of 29a (O.18 x 10(5) M(-1)), N-BOC-tetrapeptide S (0.21 x 10(5) M(-1)), 43h (0.20 x 10(5) M(-1)), and N-BOC-pentapeptide S (0.23 X 10(5) M(-1)) versus N-BOC-dipeptide S (0.10 x 10(5) M(-1)) indicate productive stabilizing binding interactions for the tripeptide S L-threonine subunit and substituent, illustrate that the entire pentanoic acid subunit of tetrapeptide S and its substituents do not significantly contribute to DNA binding affinity, and indicate that the entire beta-hydroxy-L-histidine subunit of pentapeptide S does not contribute to DNA binding affinity. With the exception of the L-threonine side chain substituent, the observations suggest that the tri- and tetrapeptide S substituent effects on the bleomycin A(2) DNA cleavage reaction are not due to substantial stabilizing binding interactions with duplex DNA. In addition, the measured apparent binding site sizes for bleomycin A(2)(3.8 base pairs), deglycobleomycin A(2) (3.9 base pairs), N-BOC-tripeptide S (3.6 base pairs), N-BOC-tetrapeptide S (3.7 base pairs), 43h (3.5 base pairs), and N-BOC-pentapeptide S (4.2 base pairs) versus N-BOC-dipeptide S (2.2 base pairs) and 29a (2.7 base pairs) suggest that it is the tripeptide S subunit of bleomycin A(2) that is fully bound to duplex DNA, that the tripeptide S L-threonine hydroxyethyl substituent detectably affects the agent interaction with duplex DNA, but that the presence or absence of the other tetrapeptide S and pentapeptide S backbone substituents do not substantially alter the binding site size or tripeptide S binding mode.

  H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OMe, corresponding to the sequence 41-49 of eglin c, inhibited human leukocyte cathepsin G and α-chymotrypsin. In order to gain further insight into the relationship between the structure and the inhibitory activity against cathepsin G and α-chymotrypsin, peptide fragments related to the above nonapeptide were synthesized by a conventional solution method and their inhibitory activities were examined. The smallest peptide which exhibited inhibitory effects on the above envymes was H-Pro-Val-Thr-Leu-OMe, corresponding to the sequence 42-45 of eglin c.

  H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OMe，对应于eglin c的第41-49位序列，对人类白细胞组织蛋白酶G和α-胰凝乳蛋白酶具有抑制作用。为了更深入地了解其结构与对组织蛋白酶G和α-胰凝乳蛋白酶抑制活性之间的关系，通过常规液相方法合成了与上述九肽相关的片段，并检测了它们的抑制活性。对上述酶表现出抑制作用的最小肽是H-Pro-Val-Thr-Leu-OMe，对应于eglin c的第42-45位序列。

  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.

  采用常规的溶液法合成了与来自家蚕血淋巴的抗蛋白酶eglin c（由70个氨基酸残基构成）相关的各种肽片段，并检验了它们对白细胞弹性蛋白酶、组织蛋白酶G和α-胰凝乳蛋白酶的抑制效应。其中，H-Arg-Glu-Tyr-Phe-OMe（eglin c 22-25）和H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OMe（eglin c 41-49）能抑制组织蛋白酶G和α-胰凝乳蛋白酶，但不能抑制白细胞弹性蛋白酶，而H-Thr-Asn-Val-Val-OMe（eglin c 60-63）能抑制白细胞弹性蛋白酶，但不能抑制组织蛋白酶G或α-胰凝乳蛋白酶，尽管eglin c对白细胞弹性蛋白酶、组织蛋白酶G和α-胰凝乳蛋白酶都具有强抑制作用。这些结果提示，eglin c与白细胞弹性蛋白酶、组织蛋白酶G和α-胰凝乳蛋白酶的相互作用部位可能各不相同。

  histidine and threonine, have been prepared and tested as inhibitors of their cognate Staphylococcus aureus aminoacyl tRNA synthetases. The arginyl derivatives were both potent nanomolar inhibitors of the Class I arginyl tRNA synthetase whereas for the Class II histidyl and threonyl tRNA synthetases, the acyl sulfamates were potent inhibitors but the adenylates had very little affinity.
