Platinum salts of organic acids, preparation thereof and applications in preparation of anticancer drugs

The invention belongs to the field of medical technology, in particular relating to an organic acid platinum salt and the preparation method thereof and the application to the preparation of anti-cancer drugs. The invention obtains the Pt(C6H14N2)Cl2 or Pt(NH3)2Cl2 through the dissolution and reaction of trans-cyclohexanediamine or ammonia and potassium chloroplatinite in water at indoor temperature; the products of the organic platinum salt are obtained through the ways that the Pt(C6H14N2)Cl2 or the Pt(NH3)2Cl2 is suspended in water, and silver nitrate is added into the water and the Pt(C6H14N2)Cl2 or the Pt(NH3)2Cl2 reacts with the silver nitrate at indoor temperature, and the formed AgCl is precipitated, filtered and removed, and the NaOH solution of the organic acid is added into the filtrates and reacts with the filtrates overnight at indoor temperature; wherein, the organic acid is ursolic acid, asiatic acid, betulinic acid, lucidenic acid C, sennoside B or rhein, etc. The anti-tumor effect experiments on mice loading Lewis lung cancer show that the organic acid platinum salt of the invention has the significant anti-tumor effects, so the organic platinum salt can be used for preparing anti-cancer drugs.

Semen cassiae oral liquid capable of relaxing bowels and lubricating intestines and preparation method thereof

The invention discloses semen cassiae oral liquid capable of relaxing bowels and lubricating intestines. The oral liquid is used for treating constipation caused by gastrointestinal heat, intestinal dry and body fluid deficiency. The oral liquid comprises, by weight, 10-50 parts of semen cassiae, 10-20 parts of scutellaria baicalensis, 10-20 parts of root of rehmannia, 10-20 parts of semen plantaginis, 10-20 parts of bighead atractylodes rhizome, 10-20 parts of radix scrophulariae, 10-20 parts of fructus aurantii, 10-20 parts of lotus leaves, 10-20 parts of fructus cannabis, 10-20 parts of gynostemma pentaphylla, 10-20 parts of mulberries, 10-20 parts of cape jasmine, 10-20 parts of curcuma aromatica, 10-20 parts of angelica sinensis, 10-20 parts of pericarpium citri reticulatae, 10-20 parts of indigo naturalis and 10-20 parts of mangnolia officinalis. The semen cassiae has the functions of clearing liver, improving vision, relaxing bowels, lubricating intestines, reducing fat and losing weight. Besides saccharides, protein and fat, the oral liquid further contains steroids, chrysophanic acid, rheum emodin and microelements, such as Fe, Zn, Mn, Cu, Ni, Co and Mo, which are essential to human bodies. The semen cassiae tastes bitter, and the taste of the semen cassiae is not easy for people to accept. By means of the oral liquid, the functions of reducing fat, losing weight, relaxing bowels and lubricating intestines are well achieved.

Preparation method and application of magnetic temperature-sensitive molecularly imprinted polymer based on eutectic solvent system

The invention discloses a preparation method and application of a magnetic temperature-sensitive molecularly imprinted polymer based on a deep eutectic solvent system, and belongs to the technical field of functional material preparation. The N-isopropylacrylamide/(3-acrylamidopropyl) trimethyl ammonium chloride eutectic solvent system is used as a functional monomer, so that the adsorption capacity of an imprinted product is improved, and the reusability is relatively high. The molecularly imprinted polymer is used as a dispersive solid-phase extraction adsorbent, and is combined with a high performance liquid chromatography to establish a novel high-selectivity separation and enrichment method for rhein in a semen cassiae sample. In order to further prove the applicability of the molecular imprinting technology, another two magnetic temperature-sensitive molecularly imprinted polymers are prepared by adopting the eutectic solvent system as a functional monomer, and can be used for efficient analysis of triterpenoid saponin compounds and aristolochic acid substances; the application value of the magnetic temperature-sensitive molecularly imprinted polymer based on the eutectic solvent system in complex sample analysis is disclosed.

Rhein phospholipid complex as well as preparation method and application thereof, rhein phospholipid complex long-circulating liposome and preparation method of liposome

In view of difficulty in clinical administration of rhein, the invention firstly provides a rhein phospholipid complex as well as a preparation method and application thereof. The preparation method of the rhein phospholipid complex includes the following steps: (1) weighing rhein and a first phospholipid according to the weight ratio of the rhein to the first phospholipid of 2:1 to 1:20, and dispersing the weighed rhein and first phospholipid in an organic solvent to obtain a reaction solution; (2) performing a reaction on the reaction solution under stirring at 30-60 DEG C for 2-24 h; and (3) performing reduced-pressure concentration on the solution after the reaction, and collecting the obtained solid to obtain the rhein phospholipid complex; and preparing a long-circulating liposome by using the rhein phospholipid complex, a second phospholipid, cholesterol, and distearoyl phosphatidylethanolamine-polyethylene glycol. According to the preparation method provided by the invention,after the rhein is compounded with the phospholipid, the solubility is improved, the druggability is improved, preparation of preparations is facilitated, and the complex is used to further prepare the long-circulating liposome, so that the biological half-life period of the rhein is effectively prolonged while efficient drug loading capacity is ensured.
