Embodiment 1

[0039] Embodiment 1: Synthesize ONT-Nd with normal pressure solution method Ⅲ Complex

[0040] Take 1mmol Nd(NO 3 ) 3 .6H 2 O was dissolved in 5mL of methanol; 2mmol of ONT was heated and dissolved in 15mL of methanol. The two solutions were mixed and reacted at 70°C (reflux) for 1 hour. After the reaction, a red suspension was obtained with a large number of complexes. A solid was formed; the solution was filtered, and the filtered solid was washed with water, methanol, and ether in turn, and dried to obtain a dark red solid product. The crimson product that this embodiment gained is through infrared spectrum (collection as shown in FIG. figure 1 shown), high-resolution mass spectrometry (spectrum as shown in figure 2 shown) and X single crystal diffraction (pattern as image 3 Shown) analysis, confirm that the dark red solid product obtained is the target complex [Nd(ONT) 2 (NO 3 ) 3 ].

Embodiment 2

[0041] Embodiment 2: Synthesize ONT-Gd with normal pressure solution method Ⅲ Complex

[0042] 1mmol Gd(NO 3 ) 3 .6H 2 O was dissolved in 10mL of water; 2mmol of ONT was dissolved in 50mL of ethanol. The two solutions were mixed and reacted at 60°C (reflux) for 10 hours. After the reaction, a red suspension was obtained, and a large amount of complex solids were formed. ; The solution was filtered, and the filtered solid was washed with water, ethanol and ether in turn, and dried to obtain a red solid product. The crimson product that this embodiment gained is through infrared spectrum (collection as shown in FIG. Figure 4 shown), electrospray mass spectrometry (spectrum as shown in Figure 5 shown) and X single crystal diffraction (pattern as Figure 6 Shown) analysis, it is determined that the obtained deep red solid product is the target complex [Gd(ONT) 2 (NO 3 ) 3 ].

Embodiment 3

[0043] Embodiment 3: Synthesize ONT-Tb with normal pressure solution method Ⅲ Complex

[0044] 1mmol Tb(NO 3 ) 3 .6H 2 O was dissolved in 50mL of water; 2mmol of ONT was dissolved in 200mL of acetone, and the two solutions were mixed and reacted at 80°C (reflux for condensation) for 20 hours. After the reaction, a red clear solution was obtained; most of them were removed by distillation under reduced pressure Solvent, a large amount of complex solids were precipitated, after cooling, the solution was filtered, and the filtered solids were washed with water, ethanol, and ether in turn, and dried to finally obtain a red solid product. The crimson product that this embodiment gained is through infrared spectrum (collection as shown in FIG. Figure 7 shown), high-resolution mass spectrometry (spectrum as shown in Figure 8 shown) and X single crystal diffraction (pattern as Figure 9 Shown) analysis, it is determined that the dark red solid product obtained is the target co...

Abstract

The invention discloses an oxonantenine rare-earth complex as well as a synthesis method and an application thereof. The rare-earth complex is obtained from a coordination reaction between oxonantenine which serves as a ligand and rare-earth metal salt in a polar solvent, and specifically, the rare-earth complex can be synthesized by virtue of a solution method or a solvothermal method. By investigating the inhibitory effect of the complex on the growth of multiple tumor cell strains, the applicant discovers that the rare-earth complex shows better antitumor activity in vitro than that of cis-platinum as a classical metal-based anti-cancer drug; meanwhile, some rare-earth complex also shows better antitumor activity in vitro than that of an oxonantenine ligand; and therefore, the rare-earth complex has a potential medicinal value, and is expected to be used for preparing various anti-cancer drugs. The structure of the rare-earth complex is as shown in formula I (as shown in Specification).

Description

technical field [0001] The invention relates to the field of metal coordination compounds, in particular to oxidized nandinaphyllin rare earth complexes and their synthesis methods and applications. Background technique [0002] Cancer is one of the most serious diseases that endanger human health. With the development of society and the deterioration of modern lifestyle and living environment, various carcinogenic factors such as genetics, environmental pollution, passive smoking, toxic and side effects of drugs, radiation, viruses, etc. , leading to an increase in the incidence of cancer in today's society. The most common and serious malignant tumors are: breast cancer, cervical cancer, lymphoma, leukemia, lung cancer, liver cancer and other types. For a long time, platinum-based drugs have been the most widely used complex small-molecule anticancer drugs. However, their clinical application is limited due to their high toxicity and side effects and easy drug resistance. ...
