ABSTRACT:
The invention provides a type of artemisinin derivatives having following structure I, its preparation method and use, as well as a pharmaceutical composition containing such artemisinin derivatives and its use. The arteminsinin derivatives of the present invention and their pharmaceutical composition containing the artemisinin derivatives. have immunosuppressive activities and can be used more safely. The composition which comprises the artemisinin derivatives can be formulated into long-term dosage forms such as tablet, pellet and the like, and have wider productive and use value.
