The present invention relates to a novel artemisinin or deoxoartemisinin-glycolipid hybrid derivatives and antiangiogenic use thereof. The artemisinin or deoxoartemisinin-glycolipid hybrid derivatives of the present invention exhibit two or more times stronger activity than the existing drugs and little or no cellular toxicity to address safety to human body.
Novel artemisinin-glycolipid hybrids were directly synthesized from 12β (C–C)-type deoxoartemisinin and glycolipid and exhibited exceptional in vitro anticancer activity, particularly against the oral carcinoma cancer cell lines, respectively. The artemisinin-glycolipid hybrids, with effective concentrations under 20 μM, demonstrated better anticancer activity than either artemisinin or glycolipid alone and showed five times more anti-oral cancer activity than either cisplatin or paclitaxel.
Novel hybrids of non acetal and acetal-type derivatives at C-12 of artemisinin and glycolipids were synthesized via efficient coupling reactions. Some of these hybrids showed potent in vivo antiangiogenic activity on the chorioallantoic membrane (CAM) that was higher than or comparable to those of fumagillin and thalidomide at a concentration of 2.5 nmol.

Synthesis and Anticancer Activity of Novel Deoxoartemisinin–Glycolipid Hybrids
The practical synthesis and anticancer activity of novel deoxoartemisinin-glycolipid hybrids, which incorporate two drugs into a single molecule and can impact multiple targets simultaneously are presented. These hybrids exhibited potent in vitro anticancer activity against several human cancer cell lines. The deoxoartemisinin-glycolipid hybrids generally demonstrated better anticancer activity than
