Abstract

The invention belongs to the technical field of medicine, discloses the application of andrographolide derivative in preparation antineoplastic agents, and relates to 15-benzyl subunit -14-deoxy-11,12-dehydrogenation andrographolide derivative and 3,19 esters thereof. The experience shows that the chemical compounds have the remarkable effects of restraining cancer cell cloning and forming and resisting migration of cancer cell and human vascular endothelial; and the chemical compounds show stronger effects of restraining tumor growth, antimetastasis and antiangiogenic in a mice transplanting tumour animal model. The chemical compounds are used as activity components for preparing antineoplastic agents, have the advantages of high efficient and low toxicity. the invention provides a new drug way for curing and preventing transfer of the tumour, expands selection range of clinical pharmacy, and is significant to taking full advantage of plant resources of the common andrographis herb.

Description

technical field [0001] The invention relates to the medicinal use of andrographolide derivatives, in particular to 15-benzylidene-14-deoxy-11,12-dehydroandrographolide derivatives and their 3,19 esters, belonging to the technical field of medicine. Background technique [0002] In recent years, due to intensified competition in modern society, increased living pressure, serious environmental pollution and other factors, the incidence and mortality of malignant tumors have remained high, and it has become the second "killer disease" that seriously threatens human health. The development of anti-tumor drugs will benefit mankind and is of great significance. [0003] Andrographolide is a diterpene lactone compound extracted from Andrographis paniculata (Burm. f.) Nees, a plant of the Acanthaceae family. It is one of the main active ingredients of the traditional Chinese medicine Andrographis paniculata. It has antipyretic, anti-inflammatory, Antibacterial, antiviral and other ...
