Description: AS-604850 is a selective PI3Kγ inhibitor, which significantly reduced the number of infiltrated leukocytes in the CNS and ameliorated the clinical symptoms of EAE mice. Treatment with this PI3Kγ inhibitor enhanced myelination and axon number in the spinal cord of EAE mice. PI3Kγ contributes to development of autoimmune CNS inflammation and that PI3Kγ blockade may provide a great potential for treating patients with MS.

More Info:
Biological target: | AS-604850 is a potent, selective and ATP-competitive PI3Kγ inhibitor with an IC50 value of 0.25 μM and a Ki value of 0.18 μM. |
In vitro activity: | Preincubation with AS604850 caused a concentration-dependent inhibition of both EoL-1 cell and human peripheral blood eosinophil chemotactic responses to PAF (Fig. 1, Fig. 2). In contrast, responses to eotaxin were unaffected by the inhibitor at concentrations up to 10 μM. Reference: Int Immunopharmacol. 2010 Sep;10(9):1017-21. https://pubmed.ncbi.nlm.nih.gov/20685403/ |
In vivo activity: | AS-604850 treatment attenuated leukocyte infiltration and clinical EAE symptoms, suggesting the protective effects of PI3Kγ inhibition to CNS tissue. This study next determined whether AS-604850 treatment enhanced myelination and axon number in the spinal cord around 24 days after EAE onset by immunostaining MBP and neurofilament or by detecting myelin sheath with LFB staining. Compared to normal control mice, vehicle-treated EAE mice exhibited remarkably reduced myelin and axonal structures in the spinal cord, especially at the lumbar level (Fig. 3A and 4). Consistently, numerous groups reported obvious myelin and axonal loss along the white matter tracts in EAE mice. Nevertheless, EAE mice treated with AS-604850 displayed significantly increased MBP, LFB and NF-staining signals at different white matter areas of the spinal cord (Fig. 3A–C and 4). Therefore, systemic treatment with PI3Kγ inhibitor reduced demyelination and axonal loss in EAE mice. Reference: Neuroscience. 2013 Dec 3;253:89-99. https://pubmed.ncbi.nlm.nih.gov/24012746/ |
