Problems solved by technology

Previous studies have shown that the compound umbelliprenin isolated from the genus Ferula in the family Umbelliferae has significantly inhibited the proliferation of gastric cancer cells and resisted their invasion and metastasis in the in vivo and in vitro anti-gastric cancer experiments. Its toxicity is low, but there is still a lot of room for improvement in terms of activity and selectivity. Therefore, chemical synthesis is used to modify its structure to improve its biological activity and druggability to explore new anti-gastric cancer drug candidates

Abstract

The invention relates to the application of a class of drugs with anti-gastric cancer effect. The drug is a monomer or composition of six terpenoid coumarin compounds obtained by chemical synthesis. Six monomeric compounds were obtained by various chemical reactions and separation and purification methods, and their chemical structures were identified by modern spectral techniques, and finally determined to be 4‑methyl‑8‑nitro‑Z‑hesperidolide (1) , 4‑Methyl‑5‑Hydroxy‑Z‑hesperidolide (2), 4‑methyl‑5‑O‑neroli‑Z‑hesperidolide (3), 4‑hydroxy‑5 ‑Methyl‑Z‑hesperidolide (4), 4‑hydroxy‑5‑methyl‑8‑hesperidyl‑Z‑hesperidolide (5), 4‑hydroxy‑5‑methyl‑ 6‑hesperidyl‑Z‑hesperidolide (6). Experimental studies have found that compounds 1-6 have better anti-proliferation effects on gastric cancer cells and higher selectivity.

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...
