Abstract

The invention relates to a pharmaceutical composition with andrographolide derivatives as active components, and a preparation method thereof. The andrographolide derivatives can be mixed with oil and emulsifying agent and made into emulsion for treating diseases due to excessive nitric oxide formation. The andrographolide derivatives have the following general formula, wherein R1 and R2 are selected from acetyl, hydroxy, alkyl, aryl, ceteroary, aralkyl, heteroaralkyl, alkyloyl group, alkenyloyl group, aroyl and heteroaroyl, or R1 and R2 are substituted by isopropylidene, and R3 is selected from Hydrogen or halogen.

Description

technical field [0001] The present invention relates to a pharmaceutical composition with the compound of the following general formula as an active ingredient and a preparation method thereof, specifically an emulsion and its preparation, and the application of the pharmaceutical composition in pharmacy. [0002] Background technique [0003] In 1896, Boorsma isolated a colorless crystalline substance from Andrographis paniculata for the first time. In 1911, it was identified as a diterpene lactone compound by Gorter structure, named androgrAPholide, and the Chinese name andrographolide, also known as Andrographolide B, is the compound of Andrographis paniculata. One of the main chemical components. Andrographolide has pharmacological activities such as anti-inflammatory, antipyretic, antiviral, antibacterial, immune regulation, inhibition of NF-κB, and antitumor. However, the structure of andrographolide determines that the chemical properties of andrographolide are re...
