| In Vitro | PI4KIII beta inhibitor 3 is a PI4KIII inhibitor extracted from patent WO/2013034738 A1, the compound of formula 3, has an IC50 of 5.7 nM. PI4KIII beta inhibitor 3 exerts significant immunosuppressive activity, with IC50 value of 3 nM in the mixed lymphocyte reaction (MLR) assay. PI4KIII beta inhibitor 3 inhibits IL2 and IFNy secretion with IC50 values of less than InM in each case. Thus, PI4KIII beta inhibitor 3 is shown to be as effective at inhibiting IL2 and IFNy secretion as conventional immunosuppressants such as cyclosporine A. IC50 on IFNy and IL-2 release of Cyclosporine A are 2nM and less than 1 nM respectively[1]. |
| In Vivo | PI4KIII beta inhibitor 3 (40 mg/kg per day, n=12) is able to delay the onset of arthritic symptoms and also to decrease symptom severity in a preventive model of arthritis compared to a vehicle control (MC 1%, n=12). PI4KIII beta inhibitor 3 reduces the anti-CII IgG titre and histological scores in the collagen-induced arthritis mouse model. Oral administration of PI4KIII beta inhibitor 3 results in prolonged graft survival in 3 out of 6 grafts in each group at day 30. Several grafts continued beating after withdrawal of the treatment (up to 60 days), indicating the induction of a certain type of graft tolerance. To evaluate the operational tolerance phenotype, animals with functional graft at day 60 are challenged with a second graft from the same donor strain or from a third party. No treatment is applied. The second grafts from the third party are rejected at day 8 (n=2) whereas second grafts from the same donor strain are functional for more than 90 days (n=2)[1]. |
| Animal Admin | Mice[1] DBA1 male mice, 8-10 weeks old, are distributed in 2 groups according to the treatment. Twelve animals received daily treatment with vehicle (1% methylcellulose), twelve others receive PI4KIII beta inhibitor 3 at 40 mg/kg/d in 1% methylcellulose. The treatment initiation started the day before the intradermal injection at the base of the tail of 100 μg of emulsified chicken collagen II in presence of complete Freund adjuvant and added heat-killed Mycobacterium butyricum. Daily inspection of the mice is performed to weight animals and quantify disease score according to the following scale (score 0: normal; score 1 : redness and/or swelling in one joint; score 2: redness and/or swelling in more than one joint; score 3: redness and/or swelling in the entire paw; score 4: deformity and/or ankylosis). On the day of sacrifice (day 42) serum are collected and anti-collagen II antibody titers are determined by ELISA. Joints are harvested, fixed in 6% paraformaldehyde, decalcified in formic acid 6% for 48 h, sliced and stained by hematoxylin and eosin staining. Hyperplasia of the synovium, infiltration of mono and polymorphonuclear cells and pannus formation parameters are scored blindly. |
