  Synthesis and DNA binding of [3-[2'-(2-acetamidoethyl)-2,4'-bithiazole-4-carboxamido]propyl]dimethylsulfonium chloride, a fragment of bleomycin A2

  摘要：

  [3-[2'-(2-Acetamidoethyl)-2,4'-bithiazole-4-carboxamido]propyl]dimethylsulfonium chloride (1), the acetyl derivative of the cationic terminal dipeptide of bleomycin A2, has been synthesized and its binding to DNA and poly(dA-dT) has been studied by proton NMR and fluorescence spectroscopy. The spectral perturbations which occur upon binding of the compound to either nucleic acid indicate that that portion of bleomycin which binds to the nucleic acid can, for the most part, be mimicked by the fragment. The data are discussed in terms of the structure of the drug and the drug-nucleic acid complex.

  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.
