Embodiment 1

[0035]Weigh 6-hydroxylated isoaporphine and dichlorobis(dimethylsulfoxide) platinum (II) in the same amount, 1 mmol each, and dissolve 6-hydroxylated isoaporphine in 50 mL of 95 % (volume) in methanol, dichlorobis(dimethylsulfoxide) platinum (II) was dissolved in 20mL of water, the two solutions were mixed, 2mL dimethylsulfoxide was added to the mixed solution, at 70°C After reacting for 24 hours, concentrate and evaporate to remove most of the solvent (80% of the solvent addition), cool to room temperature, stand still, and separate out a reddish-brown solid, separate the solid, and dry to obtain a reddish-brown solid product (90% yield) .

[0036] The resulting reddish-brown solid product was analyzed by infrared spectroscopy, hydrogen nuclear magnetic resonance spectroscopy, electrospray mass spectroscopy, single crystal diffraction and ultraviolet spectroscopy. The specific spectral characteristics are as follows:

Abstract

The invention discloses a novel platinum (II) coordination compound of an oxidation iso-aporphine alkaloid (namely mono-chloride-dimethylsulfoxide-6-hydroxide radical oxidation iso-aporphine platinum (II)) and a synthesizing method and application of the mono-chloride-dimethylsulfoxide-6-hydroxide radical oxidation iso-aporphine platinum (II). According to the coordination compound, 6-hydroxide radical oxidation iso-aporphine and dichloro-dimethylsulfoxide platinum (II) which are equal in amount of substance are weighed and dissolved in a polar solvent, and a target product is obtained after a heating reaction or a reflux reaction; in detail, a solution method can be used for synthesizing, and meanwhile a solvothermal method can be used for synthesizing. Proliferation inhibition, on HepG2, SK-OV-3, SK-OV-3/DDP, BEL-7404, T-24 and other human tumor cell stains, of the coordination compound is investigated, the result shows that the novel platinum coordination compound has obvious anti-tumor activity in vitro and good potential medicinal value and is expected to be used for preparation of kinds of anti-tumor drugs. The chemical structural formula of the coordination compound is as follows (please find the formula in the specification).

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a platinum (II) complex of oxidized isoaporphine alkaloids, i.e. monochloro-dimethyl sulfoxide 6-hydroxyl-oxidized isoaporphine platinum (II) and its synthetic methods and applications. Background technique [0002] Cancer (mainly referring to malignant tumors) is one of the most serious diseases that endanger human health. The most common and serious malignant tumors in my country mainly include: breast cancer, cervical cancer, lymphoma, leukemia, lung cancer, liver cancer and other types (FarrellN, etal.CancerRes.,1992), while anti-tumor drugs are gradually developed along with the great threat of cancer to human health. After decades of research and development by scientific researchers, different types of anti-tumor drugs with different efficacy characteristics and different mechanisms of action have been launched and applied in clinical treatment and adjuvant therapy.
