Research progress of structural modification of oridonin / 药学实践杂志

Oridonin is an en-kaurene diterpenoids compound which was found to have effect on tumor in vitro.But the clinical application has been limited because of poor water solubility,low bioavailability and oral absorption.Many scholars conducted a large number of structure modification researches of oridonin to search for new diterpenes with higher bio-activities and better bio-availabilities,and to develop new antitumor drugs.In this paper,studies on this aspect of oridonin were re-viewed.
