  Strong positive cooperativity in binding to the A3T3 repeat by Hoechst 33258 derivatives attaching the quinoline units at the end of a branched linker

  摘要：

  Hoechst 33258 derivatives with additional interacting moieties attached at the ends of branched linkers were synthesized, and their DNA binding properties were investigated with regard to the A3T3 repeat by measuring fluorescence spectra. The binding property of the ligand was investigated by fluorescence titration, and the titration data were analyzed using the McGhee-von Hippel method. Ligand 6Q with the quinolin-6-yloxyacetyl group and Ligand IQ with isoquinolin-6-yloxyacetyl group at the ends of the branched linkers exhibit highly positive cooperativity for the DNA having 5 A3T3 sites with 3 base-insertions between them with sequence selectivity. The strategy developed in this study may be generally applicable for designing ligands for repetitive DNA sequences. (C) 2015 Elsevier Ltd. All rights reserved.

  Bacterial adhesion to the glycocalyx of human host cells is of biological and medicinal importance. This process is often initiated by the interaction of bacterial lectins and specific carbohydrate ligands. Thus, adhesion of bacterial cells to glycosylated surfaces is a suitable model system to study various parameters of lectin-mediated carbohydrate recognition. Glycoarrays have become important tools

  细菌对人宿主细胞糖萼的粘附具有生物学和医学重要性。该过程通常是由细菌凝集素和特定碳水化合物配体的相互作用引发的。因此，细菌细胞对糖基化表面的粘附是研究凝集素介导的碳水化合物识别的各种参数的合适模型系统。糖阵列已成为研究这种凝集素介导的碳水化合物识别的重要工具。然而，就其糖类密度或糖配体的聚集而言，难以调节特定糖阵列的特性。因此，我们已经尝试使用化合价不同的合成簇状糖苷来改变聚苯乙烯表面上的碳水化合物密度。一系列的单声道 合成二价和三价甘露糖苷以固定在预功能化的聚苯乙烯微量滴定板上，并测试所得糖阵列作为大肠杆菌甘露糖特异性粘附的粘附表面。我们的测量结果首次揭示了这种方法以系统方式改变糖阵列配体密度的潜力。

  The present disclosure encompasses heterodimeric compositions for delivering radiolabeled and other ligands to a cell or tissue, and particularly to compositions and methods of use thereof for targeting and imaging cells and tissues expressing both an integrin and gastrin-releasing peptide receptor, in particular prostate cancer cells. The disclosure, therefore, firstly encompasses compositions that can comprise a heterodimeric probe comprising a first peptide domain comprising a moiety capable of selectively binding to an integrin; a second peptide domain comprising a moiety capable of selectively binding to a gastrin-releasing peptide receptor; a linker connecting the first peptide domain and the second peptide domain; and a prosthetic group. The first peptide domain comprises at least one tripeptide comprising the amino acid sequence of arginine-glycine-aspartate, and the second domain can be the peptide bombesin(7-14). The prosthetic group can be the fluoride isotope 18 F so that the heterodimeric probe may be detected by positron emission tomography or by single photon emission computed tomography, or a metal radionuclide. The radionuclide may be attached to the probe via a chelating tether.

• A new 18F-labeled BBN-RGD peptide heterodimer with a symmetric linker for prostate cancer imaging

  A peptide heterodimer comprises two different receptor-targeting peptide ligands. Molecular imaging probes based on dual-receptor targeting peptide heterodimers exhibit improved tumor targeting efficacy for multi-receptor expressing tumors compared with their parent single-receptor targeting peptide monomers. Previously we have developed bombesin (BBN)-RGD (Arg-Gly-Asp) peptide heterodimers, in which BBN and RGD are covalently connected with an asymmetric glutamate linker (J Med Chem 52:425-432, 2009). Although F-18-labeled heterodimers showed significantly better microPET imaging quality than F-18-labeled RGD and BBN monomers in a PC-3 xenograft model which co-expresses gastrin-releasing peptide receptor (GRPR) and integrin alpha v beta 3, tedious heterodimer synthesis due to the asymmetric nature of glutamate linker restricts their clinical applications. In this study, we report the use of a symmetric linker AEADP [AEADP = 3,3'-(2-aminoethylazanediyl)dipropanoic acid] for the synthesis of BBN-RGD peptide heterodimer. The F-18-labeled heterodimer (F-18-FB-AEADP-BBN-RGD) showed comparable microPET imaging results with glutamate linked BBN-RGD heterodimers, indicating that the replacement of glutamate linker with AEADP linker did not affect the biological activities of BBN-RGD heterodimer. The heterodimer synthesis is rather easy and straightforward. Because tumors often co-express multiple receptors, the use of a symmetric linker provides a general method of fast assembly of various peptide heterodimers for imaging multi-receptor expressing tumors.
