  摘要：

  描述了通过两种途径对博来霉素 A2 (1) 的全合成。博来霉素 A2 合成的最后一步涉及博来霉素去甲基 A2 的甲基化 (2)。这种博来霉素衍生物在机械上很受关注，并且还可以通过其已知的化学转化为博来霉素酸来提供其他博来霉素的途径。因此，所提出的合成策略代表了一种特别通用的方法，用于详细说明各种 BLM 同源物。博来霉素是由五个关键中间体构建的，描述了它们的合成。1,6-二-O-乙酰-3,4-二-O-苄基-2-O-[2,4,6-三-O-乙酰-3-O-(N-乙酰氨基甲酰基)-α-d -吡喃甘露糖基]-β-1-吡喃葡萄糖 (3) 被定量转化为其二糖氯化物 (4)，后者与 Nα 缩合，

  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.
