BACKGROUND
Andrographolide (Andro) is a main active ingredient of the natural plant Andrographis paniculata, which has special effects on bacterial infections and inflammatory diseases.
OBJECTIVE
We previously synthesized Andrographolide derivatives AL-1 and investigated its anti-inflammatory activity. For further research, we decided to modify the structure of AL-1 and expected to have better anti-inflammatory activity.
METHODS
By conjugating with anti-inflammatory and anti-bacterial group, we designed and synthesized the andrographolide derivative AL-2, AL-3 and AL-4. The anti-inflammatory activity of AL-2, AL-3 and AL-4 was also evaluated by detecting cell activity and NO release.
RESULTS
The new compounds AL-2, AL-3 and AL-4 increased cell viability in lipopolysaccharide (LPS)-induced RAW 264.7 cell, which could have a certain anti-inflammatory activity, and inhibited the release of Nitric Oxide (NO) in cells to reduce the inflammatory response of cells.
CONCLUSIONS
The new compounds AL-2, AL-3 and AL-4 may be candidates of anti-inflammatory drugs in the future.
