Abstract
Description
technical field
[0001] The invention belongs to the technical field of medicine, and specifically relates to the application of a series of terpene coumarin compounds in the preparation of drugs for treating gastric cancer. The series of compounds are six new terpene coumarin compounds chemically synthesized: 4-methyl-8 -Nitro-Z-hesperidolide (1), 4-methyl-5-hydroxy-Z-hesperidolide (2), 4-methyl-5-O-nerolyl-Z- Hesperidolide (3), 4-Hydroxy-5-methyl-Z-hesperidolide (4), 4-Hydroxy-5-methyl-8-hesperidyl-Z-hesperidin Esters (5), 4-Hydroxy-5-methyl-6-hesperidyl-Z-hesperidolide (6). Background technique
[0002] Terpenoid coumarins are an important class of natural products. About 140 compounds of this type have been reported so far, which are distributed in Rutaceae, Compositae and Umbelliferae plants in nature, among which Umbelliferae Ferulicum is the most widely distributed plant. Modern pharmacological research has found that terpene coumarins have various pharmacological a...
