  Use of Ferrocene Scaffolds as Pendant Groups in Hairpin-Type Pyrrole-Imidazole Polyamide Molecules Showing Sequence-Selective Binding to DNA Duplexes

  摘要：

  The synthesis and properties of new cotljugate molecules, Fc-PIA, composed of ferrocene (Fc) and pyrrole-imidazole polyamides (PIA) are reported. As a PIA sequence, we chose Im-Py-Im/Py-Im-Py considering its future application to the SNPs detection of genes having a GCG/CGC sequence. Two types of Fc-containing linkers, i.e., ferrocene-1,1'-dicarboxamide and ferrocenecarboxamide, were designed, and several Fc-PIPA molecules having these linkers were synthesized. Titration studies by use of circular dichroism revealed that the carboxamide-type Fc-PIA could bind to the target DNA with an association constant of 10(7) M-1. In contrast, ferrocene dicarboxamide-type compounds have slightly weaker affinity for the target DNA. However, the affinity could be recovered by replacing one of the pyrrole residues with beta-alanine. We carried out the CV measurement and observed quasi-irreversible oxidation of the ferrocene moieties in the Fc-PIA compounds. These properties of Fc-PIA indicate the potential usefulness of these molecules in electrochemical detection of genes.

  吡咯/咪唑 CPI 偶联物的高效序列特异性 DNA 链间交联

  摘要：

  我们通过合成吡咯 (Py)/咪唑 (Im)-二酰胺-CPI 偶联物 ImPyLDu86 (1) 的二聚体，使用七种不同的接头连接，开发了一种新型 DNA 链间交联剂。四亚甲基接头化合物 7b 仅在伴侣三酰胺 ImImPy 存在的情况下有效地在九个碱基对序列 5'-PyGGC(T/A)GCCPu-3' 处产生 DNA 链间交联。为了通过 7b 与 ImImPy 进行有效交联，需要两个识别位点之间的一个 AT 碱基对来容纳接头区域。消除 AT 碱基对和插入额外的 AT 碱基对并用 GC 碱基对替换显着降低了交联程度。在存在各种三酰胺的情况下，还检查了 7b 的链间交联的序列特异性。与 ImImPy 相比，ImImIm 的存在略微减少了交联产物的形成。错配伙伴 ImPyPy 和 PyImPy 不与 7b 产生链间交联产物，而 ImPyPy 和 PyImPy 在其与 7b 的匹配位点诱导有效烷基化。使用变性聚丙烯酰胺凝胶电泳和

  With the aim of incorporating a recognition element that acts as a fluorescent probe upon binding to DNA, three novel pyrrole (P) and imidazole (I)-containing polyamides were synthesized. The compounds contain a p-anisylbenzimidazolecarboxamido (Hx) moiety attached to a PP, IP, or PI unit, giving compounds HxPP (2), HxIP (3), and HxPI (4), respectively. These fluorescent hybrids were tested against their complementary nonfluorescent, non-formamido tetraamide counterparts, namely, PPPP (5), PPIP (6), and PPPI (7) (cognate sequences 5'-AAATTT-3', 5'-ATCGAT-3', and 5'-ACATGT-3', respectively). The binding affinities for both series of polyamides for their cognate and noncognate sequences were ascertained by surface plasmon resonance (SPR) studies, which revealed that the Fix-containing polyamides gave binding constants in the 10(6) M-1 range while little binding was observed for the noncognates. The binding data were further compared to the corresponding and previously reported formainido-triamides f-PPP (8), f-PIP (9), and f-PPI (10). DNase I footprinting studies provided additional evidence that the Fix moiety behaved similarly to two consecutive pyrroles (PP found in 5-7), which also behaved like a formamido-pyrrole (f-P) unit found in distamycin and many formamido-triamides, including 8-10. The biophysical characterization of polyamides 2-7 on their binding to the abovementioned DNA sequences was determined using thermal melts (Delta T-M), circular dichroism (CD), and isothermal titration calorimetry (ITC) studies. Density functional calculations (B3LYP) provided a theoretical framework that explains the similarity between PP and Hx on the basis of molecular electrostatic surfaces and dipole moments. Furthermore, emission studies on polyamides 2 and 3 showed that upon excitation at 322 nm binding to their respective cognate sequences resulted in an increase in fluorescence at 370 nm. These low molecular weight polyamides show promise for use as probes for monitoring DNA recognition processes in cells.
