  A New DNA Minor Groove Binding Motif: Cross-Linked Lexitropsins

  摘要：

  The nitrogen atoms of central pyrrole rings on two separate tripyrrolecarboxamide strands were covalently linked through poly(methylene) chains to provide a novel class of lexitropsins potentially capable of B-DNA double-strand reading via the minor groove, CD titration experiments revealed increasingly enhanced binding of 1:1 stoichiometry to the poly(dA-dT)-poly(dA-dT) DNA from the tetrakis(methylene) linkage to the heptakis(methylene) linkage, suggesting gradually growing importance of the bidentate antiparallel side by side binding. Ethidium bromide fluorescence displacement experiments on both poly(dA-dT)-poly(dA-dT) and poly(dA)-poly(dT) DNA's supported this analysis by providing quantitative measurement of intrinsic binding constants. The heptakis(methylene) linkage offered a binding enhancement of approximately 1000 times compared with that of the monomer.

  The design and synthesis are described for six new thiazolated versions of cross-linked polyamides (9a–f), in which the Th–Py–Py array of heterocycles is tethered from the central pyrrole by C5 and C7 methylene chains. The thiazole ring in the different cross-linked polyamides (9a–f) bears three different functional groups (viz. H, NHCHO and NH2). These six cross-linked polyamides were analyzed for

  描述和设计了六种新的噻唑基化版本的交联聚酰胺（9a - f），其中杂环的Th-Py-Py阵列通过C5和C7亚甲基链与中心吡咯相连。不同的交联聚酰胺（9a – f）中的噻唑环带有三个不同的官能团（即H，NHCHO和NH 2）。分析了这六种交联聚酰胺的促旋酶抑制特性，结果表明，由C7接头束缚的amTh–Py–Py（9b）对促旋酶的抑制浓度为（IC 50 = 0.01μM）是最有效的。到目前为止，在所有噻唑基化的交联聚酰胺中，该抑制剂均被分析。
