The novel metal(II)-based complexes HA-Cu, HA-Co, and HA-Ni with phenanthroline, sulfamethazine, and aromatic-aromatic coupled disulfamethazines as ligands were synthesized and characterized. HA-Cu, HA-Co, and HA-Ni all showed a broad spectrum of cytotoxicity and antiangiogenesis. HA-Cu was superior to HA-Co and HA-Ni, and even superior to DDP, showing significant inhibitory effect on the growth and development of tripe-negative breast cancer in vivo and in vitro. HA-Cu exhibited observable synergistic effects of antiproliferation, antiangiogenesis, anti-inflammatory, pro-apoptosis, and cuproptosis to effectively inhibited tumor survival and development. The molecular mechanism was confirmed that HA-Cu could downregulate the expression of key proteins in the VEGF/VEGFR2 signaling pathway and the expression of inflammatory cytokines, enhance the advantage of pro-apoptotic protein Bax, and enforce cuproptosis by weakening the expression of FDX1 and enhancing the expression of HSP70. Our research will provide a theoretical and practical reference for the development of metal-sulfamethazine and its derivatives as chemotherapy drugs for cancer treatment.

A novel chiral oxazoline copper(II)-based complex {[Cu(C13H14NO3S)2]}2 (Cu-A) was synthesized by an in situ reaction using L-methioninol, 4-hydroxyisophthalaldehyde, sodium hydroxide and copper(II) nitrate trihydrate as reactants. Its crystal structure was characterized. In vitro, Cu-A was superior to cis-dichlorodiammineplatinum (DDP) in cytotoxicity and angiogenesis inhibition. Cu-A significantly induced apoptosis of ovarian cancer cells (SKOV3) and human umbilical vein endothelial cells (HUVECs), showing significant anti-ovarian cancer and anti-angiogenesis effects. Notably, Cu-A significantly inhibits the growth of ovarian cancer in nude mice xenografted with SKOV3 cells, and it is less renal toxic than DDP. The molecular mechanism of anti-ovarian cancer and anti-angiogenesis is possibly that it down-regulates the expression of the proteins ERK1/2, AKT, FAK, and VEGFR2 and their phosphorylated proteins p-ERK1/2, p-AKT, p-FAK, and p-VEGFR2 in the VEGF/VEGFR2 signal transduction pathway to inhibit SKOV3 cell and HUVEC proliferation, induce apoptosis, suppress migration and metastasis, and inhibit angiogenesis. What's more, Cu-A significantly inhibits ovarian tumor growth in vivo by inhibiting tumor cells from inducing vascular endothelial cells to form their own vasculature and by inhibiting the expression of the anti-apoptotic protein Bcl-2 and up-regulating the expression of the pro-apoptotic proteins Caspase-9 and Bax to induce apoptosis of tumor cells.

The single crystals of two novel chiral tetranucleate copper(II)-based complexes (TNCu-A and TNCu-B) containing L-methioninol-derived Schiff-bases were obtained. Their single structures were characterized by X-ray single crystal diffraction, infrared (IR) rays, elemental analysis, and liquid chromatography-mass spectrometry analysis. TNCu-A can effectively inhibit human umbilical vein endothelial cells (HUVECs) to form a tubular structure and it induces apoptosis of human triple-negative breast cancer MDA-MB-231 cells and HUVECs in vitro in a mitochondria dependent manner. Moreover, in vivo TNCu-A can remarkably inhibit the growth of triple-negative breast cancer from which MDA-MB-231 cells were xenografted into severely immunodeficient nude mice by inhibiting proliferation, inducing apoptosis of MDA-MB-231 cells by dramatically inhibiting the expression of the anti-apoptotic protein Bcl-2 and up-regulating the expressions of proapoptotic proteins caspase-9 and Bax, and simultaneously inhibiting tumor angiogenesis by decreasing the density of vascular endothelial cells and suppressing migration and even partially inducing apoptosis.

The single crystals of two novel copper(ii)-based complexes containing l-methioninol-derived Schiff bases were obtained and characterized. The nanoparticles of these complexes were prepared and their cellular uptake was measured in MDA-MB-231 cells and HUVECs. It was found that these complexes could remarkably induce apoptosis, inhibit proliferation, suppress migration and metastasis, and inhibit angiogenesis and the growth of triple-negative breast cancer derived from MDA-MB-231 cells in vitro. Meanwhile, these complexes exhibit anticancer and antiangiogenic functions by activating the important protein molecules VEGFR2, FAK, AKT and Erk1/2 or their phosphorylated molecules p-VEGFR2, p-FAK, p-AKT, and p-Erk1/2 in the VEGF/VEGFR2 signaling pathway, collapsing the mitochondrial membrane potential, and damaging the level of reactive oxygen species.

Three novel single crystals of the metal-based complexes Cu-1, Cu-2, and Co-1 were obtained and characterized. Compared with Cu-2 and Co-1, Cu-1 showed remarkable activities of anti-cervical cancer, anti-cisplatin-resistant non-small cell lung cancer and anti-angiogenesis by downregulating the expressions of important proteins in the VEGF/VEGFR2 signaling pathway to inhibit angiogenesis and cancer cell proliferation, induce apoptosis, and suppress migration and metastasis. Moreover, Cu-1 dramatically inhibited the expression of the anti-apoptotic protein Bcl-2 and up-regulated the expressions of the proapoptotic proteins caspase-9 and Bax to induce the apoptosis of tumor cells, simultaneously decreasing the density of endothelial cells to inhibit tumor angiogenesis in cisplatin-resistant tumors.

The single crystals of two novel mixed-ligand copper(ii)-based complexes were obtained and characterized. These complexes can remarkably induce apoptosis, inhibit proliferation, suppress migration and metastasis, and inhibit angiogenesis to inhibit the growth of cervical cancer by down-regulating the expressions of the important proteins FAK, Akt and Erk1/2 or their phosphorylated proteins p-FAK, p-Akt, and p-Erk1/2 downstream of the VEGF/VEGFR2 signaling pathway.

A novel copper(II) complex with mixed ligands including ß-[(3-formyl-5-methyl-2-hydroxy-benzylidene)amino]propionic acid anion and 1,10'-phenanthroline was synthesized, and its crystal structure was thoroughly characterized. It exerted excellent inducing apoptosis, anti-angiogenesis and antiproliferative properties in vitro. The complex can bind human serum albumin (HSA) at physiological pH conditions. Remarkably, it can induce formation of the mixed parallel/antiparallel G-quadruplex structures in the G-rich sequence of the proximal vascular endothelial growth factor (VEGF) promoter, and stabilize these G-quadruplex structures, which provide an opportunity for anti-angiogenesis chemotherapeutics. Furthermore, the complex showed a strong uptake, and exhibited multiple anticancer functions by inhibiting the expression of p-Akt and p-Erk1/2 proteins and by upregulating the levels of reactive oxygen species (ROS). Because of the reported results, this new copper(II) complex qualifies itself as a potential anticancer drug candidate.

The crystals of two binuclear copper-based complexes were obtained. One complex can remarkably induce apoptosis and inhibit angiogenesis to mediate tumour growth at a greater extent. Furthermore, this complex showed a strong energy-dependent and non-endocytotic uptake and exhibited multiple anti-cancer functions by inhibiting the expressions of p-Akt and p-Erk1/2 proteins and by decreasing the levels of reactive oxygen species.

In the title compound, C(6)H(6)Cl(2)N(2)O(2)S, the O atoms of the sulfonamide group lie on one side of the benzene ring and the amino group lies on the opposite side. An inter-molecular N-H⋯Cl inter-action occurs. In the crystal, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds, forming a three-dimensional structure with supporting π-π stacking inter-actions [centroid-centroid distance = 3.7903 (12) Å]. A short Cl⋯Cl contact [3.3177 (10) Å] also occurs.
