Problems solved by technology

However, the unique molecular structure of tanshinone I is difficult to carry out structural modification. After a long period of research, Shanghai First Biochemical Pharmaceutical Co., Ltd. successfully synthesized sodium tanshinone I sulfonate in the early 1980s, which is mainly used for tanshinone II A reference substance for impurity inspection of sodium sulfonate API, the medicinal value of tanshinone I has not been fully developed

Abstract

The invention discloses a tanshinoneIderivant and application in pharmacy, which is characterized by the following: the constitutional formula is showed in the diagram; when X is -(CHR)n-, R=H or alkyl with one to eight carbons, n=0-8; or X is -(CR=CH)n-, R=H or the alkyl with one to eight carbons, n=1-4. The derivant can be produced medicinal agent for clinical application.

Description

technical field [0001] The invention relates to a class of compound derivatives and their application in pharmacy, in particular to derivatives of tanshinone I and their application in pharmacy, belonging to the technical field of medicine. Background technique [0002] Salvia miltiorrhiza is the dry root and rhizome of Salvia miltiorrhiza Bge., a plant in the Labiatae family. It was first recorded in "Shen Nong's Materia Medica", and has been recorded in successive dynasties of herbal medicines. It is bitter in taste, slightly cold in nature, and enters the two meridians of Guixin and Liver. Tool dispelling blood stasis and relieving pain, promoting blood circulation to stimulate menstrual flow, clearing away heart-fire and eliminating troubles. Salvia miltiorrhiza is a traditional Chinese medicine for promoting blood circulation and removing blood stasis, and its commonly used preparations are mainly used to treat cardiovascular and cerebrovascular diseases. The chemical...
