Embodiment 1

[0036] The synthesis process, property identification, activity experiment and detection results of the complex of the present invention will be described below by taking complex 1 as an example.

[0037] Synthesis:

[0038]

[0039]The substituted salicylaldehyde and diamine precursor corresponding to complex 1 and gallium trichloride were placed in acetonitrile, and reacted under reflux at 90°C for 24h. After stopping the reflux, a large amount of diethyl ether was added to the system to precipitate a light yellow solid, which was collected by filtration and washed with diethyl ether to obtain pure complex 1.

[0040] Characterization:

[0041] The structure of complex 1 was characterized by H-NMR, C-NMR, high-resolution mass spectrometry and infrared spectroscopy, and its photophysical properties were characterized by ultraviolet-visible absorption spectrometer and fluorescence spectrometer.

Abstract

The invention discloses a main group metallic complex with a cancer cell killing capability and preparation and application of the main group metallic complex. The main group metallic complex consistsof Schiff base type planar tetradentate ligand, p-region main group metallic ions and axial monodentate ligand, has a remarkable killing effect on cancer cells, and has the potential of being used asa micro molecule anti-cancer medicine in clinical treatment.

Description

technical field [0001] The present invention relates to a series of main group metal complexes with killing effect on cancer cells, in particular to a new type of complexes with more significant effect than the existing main group metal anticancer drugs, which have shown high anticancer effect on various cancer cell lines. Cytotoxicity and selective killing effect. Background technique [0002] Metal complex small molecule anticancer drugs are an important class of cancer chemotherapy drugs. In this field, most of the existing researches focus on the transition metal complexes mainly composed of platinum, ruthenium, gold, etc., while the anti-cancer research on the main group metal complexes is relatively less. Nevertheless, the medicinal and anticancer activities of the main group metal complexes of Groups 13, 14 and 15 have been reported. (Seng, H-L. and E.R.T.
