Abstract

The invention discloses application and preparation method of Morusignin L and derivatives thereof. According to the invention, by employing a Morusignin L total synthesis technological route, or in a process of Morusignin L total synthesis, structure modification is carried out on Morusignin L by replacing a substituent of a reaction substrate, and then Morusignin L and a series of derivatives can be synthesized. The Morusignin L is a kind of important anti-tumor activity lead compounds, a compound source can be provided for anti-tumor activity screening by synthesis of the derivatives, and Morusignin L and a series of derivatives have important meaning for searching the novel anti-tumor activity lead compounds. The preparation method of Morusignin L and the derivatives thereof has the advantages that operation is simple, raw material synthesis is low in cost and easy to perform and can be carried out in various organic solvents, the stability in air is good, the application is wide, and compatibility for various substituents is good. The derivatives have certain inhibition capability for the tumor cells growth activity, and can be used as an antitumor drug or an antitumor drug lead compound.

Description

technical field [0001] The invention relates to the technical field of medicinal chemistry, in particular to an application and preparation method of Morusignin L and its derivatives. Background technique [0002] Mori Cortex (Mori Cortex) is the dried root bark of Morusalba L., a plant of the Moraceae family. It was first recorded in "Shen Nong's Materia Medica" and listed as a traditional Chinese medicine. , sweet and cold in taste, descending in nature, mainly enters the lungs, and is specialized in purging lung heat and relieving asthma. The chemical composition of Morus alba is mainly Diels-Alder adducts and flavonoids, in addition to terpenes, coumarins, sugars, sterols, and volatile oils. Pharmacological studies have shown that Morus alba has various pharmacological activities, including anticancer activity. However, through literature inspection, it is found that no further research has been carried out on the anticancer active ingredients of Morus alba. [0003] ...
