  Tris-benzimidazole derivatives: design, synthesis and DNA sequence recognition

  摘要：

  Two tris-benzimidazole derivatives have been designed and synthesized based on the known structures of the bis-benzimidazole stain Hoechst 33258 complexed to short oligonucleotide duplexes derived from single crystal X-ray studies and from NMR. In both derivatives the phenol group has been replaced by a methoxy-phenyl substituent. Whereas one tris-benzimidazole carries a N-methyl-piperazine at the 6-position, the other one has this group replaced by a 2-amino-pyrrolidine ring. This latter substituent results in stronger DNA binding. The optimized synthesis of the drugs is described. The two tris-benzimidazoles exhibit high AT-base pair (bp) selectivity evident in footprinting experiments which show that five to six base pairs are protected by the tris-benzimidazoles as compared to four to five protected by the bis-benzimidazoles. The tris-benzimidazoles bind well to sequences like 5-TAAAC, 5'-TTTAC and 5'-TTTAT, but it is also evident that they can bind weakly to sequences such as 5'-TATGTT-3' where the continuity of an AT stretch is interrupted by a single G-C base pair.

  苯并咪唑-恶唑偶联物作为微管靶向剂的合成及生物学评价

  摘要：

  合成了一系列苯并咪唑-羟吲哚缀合物，并评估了它们的细胞毒性活性。细胞毒性测定结果表明，缀合物5c和5p对人乳腺癌细胞系（MCF-7）显示出有希望的细胞毒性。细胞周期分析表明，这些缀合物诱导了MCF-7细胞在G2 / M期的细胞周期停滞。微管蛋白聚合测定结果表明，这些结合物抑制微管蛋白聚合，IC 50值分别为1.12和1.59μM。免疫荧光分析还表明，这些结合物可有效抑制MCF-7细胞中的微管组装。此外，分子对接研究表明这些缀合物5c和5p与微管蛋白相互作用并有效结合。总体而言，结果表明这些苯并咪唑-羟吲哚共轭物通过抑制微管蛋白聚合而具有细胞毒性。

  A catalytic Fe(III)/Fe(II) redox cycling approach has been examined and applied towards synthesis of a wide range of benzimidazole, bis-benzimidazole and imidazopyridine derivatives from oxidative coupling of aromatic ortho-diamines with aromatic as well as heterocyclic aldehydes bearing different types of substituents. This versatile and convenient method has further proven to be particularly useful

The 5- and 6-nitro derivatives of 2-(4-methoxyphenyl) benzoxazole, 2-(4-methoxyphenyl)benzothiazole, and 2-(4-methoxyphenyl)indole were synthesized and their relative activity as topoisomerase I inhibitors determined.

  The synthesis of a purine containing analogue (1) of bisbenzimide (2) and its DNA binding properties are described. Analogue 1 is found to have increased tolerance for binding to GC sites implying the formation of the new hydrogen bonds between guanine-2-NH2 in the minor groove of DNA and the concave purine N3 atom of 1.
