dimethylamino micheliolide (ACT001)

Pharmacological inhibition of the TNF signaling pathway with R-7050 completely abolished the synergistic efficacy of RT/TMZ/ACT001. Taken together, our results demonstrate that ACT001 combined with RT/TMZ can overcome the immunosuppressive barrier of GBM to achieve immune cure in GBM via TNF-CXCL10-CD8+ signaling, strongly suggesting the priority of combining ACT001 with RT/TMZ rather than with αPD-1 in clinical trials.

The orphan drug ACT001, as the SL derivative, has been used in the treatment of glioma, which demonstrated significant potential for the development of such compounds...Furthermore, the orthotopic glioma model using live animal fluorescence imaging demonstrated the therapeutic effect of 1e on MG in vivo and pharmacokinetic studies indicated 1e with a favorable pharmacokinetic profile. Moreover, we performed competitive activity-based protein profiling (ABPP) to explore the potential targets of SL derivatives in U87 cells, providing a basis for the follow-up studies of MG.

Focusing on the MDK/c-Myc complex could be an effective approach to combat resistance to TMZ in glioma. Therapy with ACT001 may be a novel approach to improve the efficacy of TMZ-based chemotherapy in patients with glioma. Further preclinical and clinical studies are warranted to validate the therapeutic potential of targeting the MDK/c-Myc complex in glioma treatment.

Moreover, ACT001, an orphan drug to treat glioblastoma, disrupts this feed-forward activation loop by inhibiting the STING→NF-κB pathway in microglia, thereby alleviating EAE. These findings emphasize the importance of interactions and bi-directional activations between microglia and Th17 in the autoimmune neuroinflammation, and provide rationale for further investigation on ACT001 as therapeutic option for autoimmune inflammatory diseases driven by similar mechanisms.
