The cytotoxic substance of A. chinense saponins (ACSs) was isolated using ethanol extraction and purified with the D101 macroporous adsorption resin approach. We investigated the anticancer activity of ACSs in the B16 melanoma and 4T1 breast carcinoma cell lines. Methylthioninium chloride and hematoxylin-eosin staining with Giemsa dyestuff were used when the cells were treated with ACSs. The results showed that the cells morphologies changed significantly; ACSs induced cell death in B16 and 4T1 cells based on acridine orange/ethidium bromide double fluorescence staining, with the number and degree of apoptotic tumor cells increasing as ACS concentration increased. ACSs inhibited the proliferation of B16 and 4T1 cells in a dose-dependent manner. They also inhibited cell migration and colony formation and exhibited a concentration-dependent effect. In addition, ACSs apparently inhibited the growth of melanoma in vivo. The preliminary antitumor in vivo assay revealed that early medication positively affected tumor inhibition action and effectively protected the liver and spleen of C57 BL/6 mice from injury. This study provides evidence for the cytotoxicity of ACSs and a strong foundation for further research to establish the theoretical basis for cell death and help in the design and development of new anticancer drugs.

Amino-quinolines are potential candidates that may provide some insight into the current chemotherapeutic research due to their demonstrated anti-cancer activity. This led us to synthesize and explore a new amino-azo-quinoline ligand H2L 1 and its square planar nickel(II) complexes [Ni(HL)(OAc)], 2 and [Ni(HL)Cl], 3 and the structures were determined by SCXRD. Theoretical investigation of redox orbitals of the complexes discloses that the reduction process is due to ligand reduction whereas both metal and ligand are contributing towards oxidation.

A new methodology is presented for the rapid, specific, and sensitive detection of irinotecan (CPT-11), a chemotherapeutic agent utilized in the treatment of cancer, along with its metabolically active derivative, SN-38, via laser desorption/ionization mass spectrometry (LDI MS). The method includes the detection of camptothecin (CPT), which can be utilized as an internal standard for the quantitative assessment of both CPT-11 and SN-38 in mouse serum. The approach utilizes a plasmonic two-dimensional (2D) black phosphorus nanosheet (BPN)-gold nanomatrix (BP@Au) in LDI MS.

Azo dye was used to prepare a new series of complexes with chlorides of rhodium (Rh), ruthenium (Ru), and corona (Au). The prepared materials were subjected to infrared, ultraviolet-visible, and mass spectrometry, as well as thermogravimetric analysis, differential calorimetry, and elemental analysis. Conductivity, magnetic susceptibility, metal content, and chlorine content of the complexes were also measured.

The work is aimed to investigate whether midazolam functions in thyroid cancer and reveal the potential mechanism of action. Cell viability was detected by CCK-8 method when treated by varying doses of midazolam to detect the cytotoxicity of midazolam on human thyroid follicular epithelial cell line and thyroid cancer cell lines. In thyroid cancer cells, EDU staining, wound healing and transwell assays were respectively used to detect cell proliferation, migration and invasion.

The development of novel therapeutic strategies enabling the selective destruction of tumors while sparing healthy tissues is of great interest to improve the efficacy of cancer chemotherapy. In this context, we designed a β-glucuronidase-responsive albumin-binding prodrug programmed to release a potent Isocombretastatin A-4 analog within the tumor microenvironment. When injected at a non-toxic dose in mice bearing orthotopic triple-negative mammary tumors, this prodrug produced a significant anticancer activity, therefore offering a valuable alternative to the systemic administration of the parent drug.
