The synthesis of a series of andrographolide derivatives was described and their inhibitory effects on TNF-alpha and IL-6 secretion in mouse macrophages were also evaluated. Most of the tested compounds showed inhibitory effects, and the compounds with the structure of 12-hydroxy-14-dehydroandrographolide showed better inhibitory activity than the compounds with the structure of isoandrographolide.

Synthesis and Preliminary Anti-HIV Activities of Andrographolide Derivatives
indicated that andrographolide was a potential anti-HIV therapeutic agent. In the paper, the synthesis of a series of andrographolide derivatives was described and their anti-HIVactivities were evaluated in vitro. As compared with TI, compounds 5c, 5d and 5i showed moderate inhibitory activities on the cytopathic effect with TI above 10. Among the derivatives, compound 5i was the best one with TI > 51
