ABSTRACT
<p><b>AIM</b>To search for new artemisinin derivatives with higher immunosuppressive activity.</p><p><b>METHODS</b>Two kinds of new artemisinin derivatives containing polyethylene glycol group were synthesized from dihydroartemisinin via condensation and esterification. These compounds were assayed for their inhibitory activity on ConA-induced T cell proliferation and LPS-induced B cell proliferation.</p><p><b>RESULTS</b>Twenty three new compounds (2a - 2f, 3a - 3d, 4a - 4f, 6a, 6b and 7a - 7g) were synthesized and identified by 1H NMR and elemental analysis.</p><p><b>CONCLUSION</b>These compounds had immunosuppressive activity in vitro. Among them, the symmetrical substituted compound 2 and 6 had higher activity than mono-substituted compound 3, 4 and 7. Especially, compounds 2a - 2f remarkably exhibited higher inhibition in comparison with artemisinin and artesunate.</p>
