Artemisinin (Qinghaosu) and its semi-synthetic derivatives have been demonstrated to alleviate neuroinflammatory response in the central nerve system (CNS). In this review, we summarized that artemisinins are capable to treat neuroinflammtion-related CNS diseases in both direct (via regulating inflammatory process in the CNS, exerting anti-oxidative stress and neuroprotective effect, and preventing Aβ accumulation) and indirect (via maintaining BBB integrity, suppressing systemic inflammation and alleviating intestinal inflammtion) manner. However, the precise mechanism of their anti-neuroinflammatory effects and potential neurotoxicity, which hindered further progress in these aspects, remains unclear. We suggest that further understanding of the PK/PD properties and structure-action relationship of atemisinin and its derivatives will facilitate the development of new therapeutics with better curative effects and safety.
