Abstract

The invention provides a spirosolane glycoalkaloid(3beta,5alpha,22alpha,25R)-spirosolane-3-O-beta-D-glucopyranosyl-(1 to 2)-O-beta-D-glucopyranosyl-(1 to 4)-beta-D-galactopyranoside, and a preparation method and a use thereof. The spirosolane glycoalkaloid has an inhibition effect on human lung gland cancer cell A549, human maxicell lung cancer cell H460 and human lung squamous cancer cell SK-MES-1, the 50% inhibiting concentration of the A549 cell is 19.22 [mu]g/ml, the 50% inhibiting concentration of the H460 cell is 80.03 [mu]g/ml, and the 50% inhibiting concentration of the SK-MES-1 cell is 54.20 [mu]g/ml. The (3beta,5alpha,22alpha,25R)-spirosolane-3-O-beta-D-glucopyranosyl-(1 to 2)-O-beta-D-glucopyranosyl-(1 to 4)-beta-D-galactopyranoside prepared in the invention, and a preparation thereof, can be used for treating non-small cell lung cancers.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of glycoside alkaloids and medicinal applications, and in particular relates to a spirosteroid alkaloid type glycoside alkaloids and a preparation method and application thereof. Background technique [0002] Glycoalkaloids are mainly distributed in plants of Solanaceae and Liliaceae, and are composed of hydrophobic aglycones and hydrophilic oligosaccharide chains. The aglycones include spirostanoids, solanesines and other steroidal derivatives Three kinds, the oligosaccharide chain is composed of 3 to 4 monosaccharides, which is a steroidal saponin. Plants synthesize glycoalkaloids mainly to defend against the invasion of microorganisms, animals and insects. Therefore, glycoalkaloids have certain toxicity, but at the same time, they also have the functions of lowering cholesterol and high blood pressure, anti-inflammation, promoting blood circulation and analgesia, anti-allergic, It ...
