用二甲苯基将尿喀啶与cyclen连接,合成了一种新的配体。并发现这种配体在水中能够与Zn2+快结合,生成的含锌配合物可以选择性地c进pUC 19质粒DNA的切割,而且这种配合物在c进 DNA切割过程中形成了一种稳定的大分子结构。 这种cyclen衍生物具有的多样性使它们在众多领域具有广的应用价值。例如,某些金属(如铜、锌等)...
A series of chiral peptides has been prepared, bearing a 1,4-dihydronicotine amide and a zinc cyclen moiety. The metal complex reversibly binds flavins in aqueous solution, while the dihydronicotine amide serves as a NADH model transferring a hydride to the flavin within the assembly. The ...

A luminescence sensor of inositol 1,4,5-triphosphate and its model compound by ruthenium-templated assembly of a bis(Zn2+-cyclen) complex having a 2,2'-bip... A new supramolecular complex (Ru(Zn2L4)3) was designed and synthesized as a luminescence sensor for inositol 1,4,5-triphosphate...
Zn2AzacrownA multi-nucleating azacrown conjugate (5a) consisting of two 3,5-bis(1,5,9-triazacyclododecan-3-yloxymethyl)benzyl groups attached to 1 and 7 sites of cyclen was prepared and tested as an artificial ribonuclease. The conjugate in the presence of five equivalents of zinc nitrate ...
As an important nucleobase in RNA, uracil was introduced into the side chain of cyclen (1,4,7,10-tetraazacyclododecane) by using phenylene dimethylene grou... CQ Xia,N Jiang,J Zhang,... - 《Bioorganic & Medicinal Chemistry》 被引量: 119发表: 2006年 Syntheses, Structures, and Properties ...
We have previously shown that the nucleobase thymine binding to Zn2+ -cyclen (cyclen=1,4,7,10-tetraazacyclododecane) complex became stronger by appending acridine, naphthalene, or quinoline rings to the cyclen. Amongst these, the pendant bis((1-naphthyl)methyl) or bis((4-quinolyl)methyl) ...
