Embodiment 1

[0017] Example 1: Compound (I) Separation Preparation and Structure Confirmation

[0018] Separation method: (a) crush the dry leaves (2kg) of Shiwei, extract with 75% ethanol under heat reflux (20L×3 times), combine the extracts, concentrate until no alcohol smell (4L), and then use petroleum ether (4L ×3 times), ethyl acetate (4L×3 times) and water-saturated n-butanol (4L×3 times) were extracted to obtain petroleum ether extract, ethyl acetate extract and n-butanol extract respectively; (b) In the step (a), the n-butanol extract is removed with D101 type macroporous resin, first eluted with 15% ethanol for 6 column volumes, then with 70% ethanol for 10 column volumes, collected 70% eluate, and reduced Concentrate under pressure to get 70% ethanol elution concentrate; (c) in step (b), 70% ethanol elution concentrate is separated with normal phase silica gel, and the volume ratio is 80:1 (8 column volumes), 30:1 successively (8 column volumes), 15:1 (8 column volumes) and 5:1...

Abstract

The invention discloses a medicinal composition of carbocisteine and treatment effects of the medicinal composition for leukemia. The medicinal composition of carbocisteine provided by the invention contains carbocisteine and a natural product compound (I) which is obtained by separating the dried folium pyrrosiae and has the novel structure, when carbocisteine and the natural product act independently, certain treatment effect can be achieved on leukemia, when carbocisteine and the natural product are mixed for use, the treatment effect for leukemia is more obvious, the medicinal composition can be developed into the medicine for treating leukemia, and compared with the prior art, the medicinal composition has outstanding substantive features and obvious progress.

Description

technical field [0001] The invention belongs to the field of biomedicine and relates to a new application of carbocisteine, in particular to a pharmaceutical composition of carbocisteine ​​and its therapeutic effect on leukemia. Background technique [0002] Carbocisteine ​​is S-(carboxymethyl) cysteine, which is prepared by reacting cysteine ​​and chloroacetic acid under certain conditions. Carbocisteine ​​is a phlegm-resolving and cough-relieving drug, which mainly affects the secretion of bronchial glands at the cellular level, increases the secretion of low-viscosity salivary protein, reduces the production of high-viscosity fucoidin, and reduces the consistency of sputum, making it easier to cough up , clinically used for chronic bronchitis, bronchial asthma and other diseases caused by thick sputum, difficulty in expectoration, and phlegm obstructing the airway. [0003] So far, there has been no report on the correlation between carbocisteine ​​and its pharmaceutical...
