Bifunctional tetrazole-carboxylate ligand based Zn(ii) complexes: synthesis and their excellent potential anticancer properties

Transition metal coordination complexes have provided cancer treatment with new insights to overcome the limitations of current chemotherapeutic agents. Utilization of bifunctional tetrazole-carboxylate ligands with Zn(ii) obtained two self-assembled complexes [Zn(HL¹)(bipy)_3/2(H₂O)]·CH₃OH·4(H₂O) (1) (H₃L¹ = 1,3,5-tri(2-carboxymethyltetrazol-5-yl) benzene) and [Zn(L²)₂(H₂O)₂]₂·2H₂O (2) (HL² = (5-pyridin-3-yl-tetrazol-2-yl)-acetic acid). The X-ray diffraction results showed that the two complexes displayed a two-dimensional (2D) layer structure and a one-dimensional (1D) layer structure. Nanocoprecipitation with DSPE-PEG-2000 resulted in the formation of complex nanoparticles (NPS) with excellent water dispersion. In vitro CCK-8 assay indicated the two NPs exert high cytotoxicity and sensitivity and a low half-maximum inhibitory concentration (IC₅₀) towards HeLa than HepG2 cells. In addition, the cytotoxicity was also confirmed by live/dead co-stained experiments. The presented experimental results showed the 1 and 2 NPs were capable of inhibiting cell proliferation in vitro and may help design coordination complex-based anticancer candidates for cancer cells.

Construction of highly energetic metal-organic frameworks with a nitrobenzene derivative

Three metal–organic frameworks [CdL(DMF)]n 1, {[CuL(H2O)(DMF)]•DMF•0.5H2O}n 2 and [Nd(HL)L(DMF)3]n 3 have been synthesized with a nitrobenzene derivative 4-((5-hydroxy-2,4-dinitrophenoxy)methyl)-3-nitrobenzoic acid (H2L). Compound 1 has a dense three-dimensional framework with 1D Cd...
