  Structure-activity relationship of a series of C-terminus modified aminoalkyl, diaminoalkyl- and anilino-containing analogues of the benzoic acid mustard distamycin derivative tallimustine: Synthesis, DNA binding and cytotoxicity studies

  摘要：

  As part of our investigations into the design of more cytotoxic analogues of the experimental anticancer drug tallimustine, 1, C-terminus modified aminoalkyl-, 2a-c, diaminoalkyl-, 3, and anilino-containing, 4, derivatives have been synthesized. Compounds 2a-c differ by 2, 3, or 4 methylene units in the C-terminus, respectively. Results from an ethidium displacement study on poly(dA-dT), poly(dG-dC), calf thymus DNA and T4 coliphage DNA showed that compounds 2-4 interact in the minor groove of the polynucleotides with a preference for poly(dA-dT) over poly(dG-dC). Compound 4 bound more weakly to the DNAs than 2a-c and 3. Using a CD dilution assay compounds 2a-c and 3 were demonstrated to bind irreversibly to calf thymus DNA. The sequence selectivity by which compounds 2-4 alkylate DNA was demonstrated using a Tag polymerase stop assay. All the compounds alkylated preferentially at the 3'-purine residue in a 5'-TTTTGPu-3' sequence (Pu = A or G). This observed sequence specificity is similar to that of tallimustine and a related compound 5. At an equimolar concentration the aminoalkyl compounds 2a-c (2b > 2a > 2c), and diaminoalkyl compound 3 were more efficient at alkylating these sequences than the anilino compound 4. Following a one hour exposure of human chronic myeloid leukemia K562 cells, compounds 2b and 3 have lower IC50 values (1.64 mu M and 3.03 mu M, respectively) than tallimustine (5 mu M) and similar Values to a related compound 5 (2.2 mu M). The order of cytotoxicity for all the compounds is 2b > 5 > 3 > 2a > 1 > 2c = 4. These results indicate that the cytotoxicities of these compounds are related to their relative ability to alkylate the consensus DNA binding sequence. (C) 1997 Elsevier Science Ltd.

  摘要：

  许多抗肿瘤药的作用机制都涉及DNA损伤，这可能是由于药物与DNA或与DNA结合蛋白的直接结合而引起的。但是，大多数DNA相互作用剂仅具有有限程度的序列特异性，这意味着它们可能击中所有细胞基因。DNA小沟结合剂（其中双霉素A的衍生物起着重要作用）由于与富含胸腺嘧啶-腺嘌呤（TA）的序列具有很高的选择性，可以显着改善癌症的治疗，增加基因特异性。我们现在报告和讨论合成的，体外和体内活性以及二霉素A的α-卤代丙烯酰胺基衍生物的一些机理特征。这项工作的最终结果是选择brostallicin 17（PNU-166196）。Brostallicin，目前处于II期临床试验中，与广谱霉素衍生物塔木斯汀相比，它具有广谱的抗肿瘤活性和更高的凋亡作用。与临床测试的DNA小沟结合剂相比，brostallicin的重要体外毒理学特征是对人类造血祖细胞的骨髓毒性与对肿瘤细胞的细胞毒性之间的比率非常高。brostall
