TL;DR: In this article, the first generation anionic iron(III) porphyrin [Fe(TSPP)] and the second generation anion complexes [Fe (TDFSPP)], [Fe[TCFSPP], and [Fe [TDCSPP] were immobilized into three-dimensional macroporous layered double hydroxide (3DM-LDH), using the direct reconstruction of 3DMLDH from macroporus mixed oxides MOX or the anionic exchange on DDS intercalated 3DM- LDH.

Structure/Nuclease Activity Relationships of DNA Cleavers Based on Cationic Metalloporphyrin−Oligonucleotide Conjugates†
TL;DR: It is shown that the most efficient conjugate for oxidative DNA cleavage was a manganese tetracationic porphyrin-oligonucleotide compound, in order to avoid the reduction of the activated DNA cleaver by the excess of reducing agent.

Electrochemistry meets enzymes: instrumental on-line simulation of oxidative and conjugative metabolism reactions of toremifene
Wiebke Lohmann,Uwe Karst +1 more
TL;DR: In the absence of GST, not all GSH adducts are formed, proving the necessity of a phase II enzyme to simulate the complete metabolic pathway of xenobiotics in an on-line EC/LC/MS system.
Journal ArticleDOI
Metal-assisted light-induced DNA cleavage activity of 2-(methylthio)phenylsalicylaldimine Schiff base copper(II) complexes having planar heterocyclic bases.
TL;DR: A profound effect of the substituents of the phenanthroline bases is observed on the binding of the complexes to the calf thymus (CT) and in the cleavage of supercoiled (SC) pUC19 DNA.

An effective approach to artificial nucleases using copper(II) complexes bearing nucleobases
Jin-Tao Wang,Qing Xia,Xiao-Hui Zheng,Huo-Yan Chen,Hui Chao,Zong-Wan Mao,Zong-Wan Mao,Liang-Nian Ji +7 more
TL;DR: High DNA cleavage ability and selectivity of novel copper(ii) complexes could be attributed to the synergic effects of the metal center and the pendant nucleobases.
