Redox active and inactive binuclear cobalt(II) and zinc(II) complexes with N6O/N3O coordinating ligands: synthesis, biological activities and cytotoxicity
Four complexes, namely [Zn2L1(OAc)2](PF6) (); [Zn2L1(OAc)2](BPh4) (); [Co2L1Cl2](PF6) (); and [Zn2L2(PhCOO)2Cl] () (L1 =
DNA binding, cleavage, and cytotoxicity of binuclear phenolate nickel(II) complexes
Abstract Three binuclear phenolate complexes, [Ni2(L1)2(OAc)](BPh4)·DMF (1), [Ni2(L2)2(OAc)](BPh4) (2), and [Ni2(L3)2(OAc)](OH)·3H2O (3), where L1 =
Synthesis, cytotoxicity, topoisomerase I inhibition and molecular docking of novel phosphoramide mustard sophoridinic acid analogues
Mechanistic studies showed that this class of compounds acted as novel topoisomerase I (Topo I) catalytic inhibitors by preventing the binding of Topo I to DNA and inhibiting the cleavage of DNA, and molecular docking studies revealed that the binding energy for these compounds was comparable to that for classic TopO I inhibitors CPT and HCPT, indicating that the compounds have an interaction with DNA and Topo II.
Polyanthumin, a novel cyclobutane chalcone trimmer from Memecylon polyanthum
A novel unusual trimmer chalcone, polyanthumin, together with five known compounds myricetin 3-O-(3″-O-galloyl)-α-l-rhamnopyranoside, which provided the first example of these class flavonoids from the family Melastomataceae and the antitumor activities for 2–4 were reported for the first time in this study.
Comparison of nuclease activities of binuclear metal complexes with N6O coordinating heptadentate ligands: [M2L(OAc)2]+ (M = Ni, Mn, L = 2,6-bis(((2-(dimethylamino)ethyl)(pyridin-2-ylmethyl)amino)
Four complexes, [Ni2L(OAc)2](PF6) (1), [Ni2L(OAc)2](BPh4) (2), [Mn2L(OAc)2](PF6) (3) and [Mn2L(OAc)2](BPh4) (4) (L =
