PRT-060318 is a novel Syk inhibitor.
Heparin-induced thrombocytopenia is a heparin therapy complication in which IgG antibodies against the platelet factor 4-heparin complex activate platelets. The FcγRIIA clustering initiates signaling cascades involving tyrosine kinases, such as spleen tyrosine kinase (Syk).
In vitro: PRT-060318 was identified as a potent inhibitor of purified Syk kinase. Syk kinase was inhibited by 92%, while the activities all other kinases retained more than 70% when PRT-060318 were evaluated at a concentration of 50 nM in a broad panel of kinase enzyme assays. In addition, PRT-060318 could dose-responsively inhibited convulxin-induced human PRP aggregation. Moreover, it was found that PRT-060318 was able to dose-responsively inhibit the increases in intracellular calcium in convulxin-treated platelets [1].
In vivo: Animal study showed that in contrast to vehicle-treated mice developed the expected thrombocytopenia, PRT-060318-treated mice had no significant change in platelet counts after injection of heparin. Moreover, the nadir platelet counts of PRT-060318-treated mice were found to be significantly higher than control mice. The PRT-060318-treated mice showed no bleeding diathesis or other adverse effects. In addition, PRT-060318 treatment in crush thrombosis model resulted in significant inhibition of platelet deposition without changing bleeding time [1].
Clinical trial: Up to now, PRT-060318 is still in the preclinical development stage.

Cell experiment: | PRT318 is dissolved in DMSO. Cells are incubated for 14 days in 24-well plates. CLL cells are cultured under standardized conditions on NLC or in suspension, in the presence or absence of PRT318 and P505-15. At 24, 48, 72 h, CLL cells are collected and assayed for cell viability[2]. |
Animal experiment: | Mice: Heparin-induced thrombocytopenia (HIT) model mice are treated with KKO (20 mg/kg body weight, intraperitoneally) on day 0. The mice are divided into sex- and weight-matched experimental and control groups. On days 1 to 7, experimental mice (n=6) receives PRT318 (30 mg/kg body weight) orally via gavage twice a day, whereas control mice (n=6) receives vehicle only (sterile water). Both groups receives heparin (1600 U/kg body weight, subcutaneously) once daily. Mice are anesthetized by isoflurane inhalation for injections and blood collections[1]. |
