Biological Activity
Description
PRT-060318 (PRT318) is a novel selective inhibitor of the Syk tyrosine kinase with an IC50 of 4 nM, as an approach to HIT treatment.
Targets
Syk (Cell-free assay)
4nM
In vitro
PRT318 inhibits platelet activation via GPVI/FcRγ, an ITAM receptor complex, but not via ADP or thrombin, which are G-protein coupled receptors. PRT318 effectively antagonizes CLL(chronic lymphocytic leukemia) cell survival after BCR triggering and in nurse-like cell-co-cultures. PRT318 inhibits Syk and extracellular signal-regulated kinase phosphorylation after BCR triggering.
In Vivo
In both rabbit and pig models, intravenous infusion of PRT060318 targets maximal inhibition of Syk kinase activity and significantly inhibits arterial thrombosis. The antithrombotic activity of PRT060318 in pigs is remarkable because it was achieved with complete inhibition of CVXN-induced platelet aggregation, with no effect on ADP-induced platelet aggregation, and no prolongation of ear bleeding time. Also, Syk inhibitor PRT318 is an active agent in HIT. Inhibition of Syk signaling with the orally bio-available PRT318 limits the thrombocytopenic and thrombotic effects of HIT IC in vivo.
The numbers of cells treated with various doses of PRT318 are followed over time. PRT318 inhibits growth of the sensitive cell lines in a dose-dependent manner. Two sensitive (LY7 and LY18) and 2 resistant (LY3 and LY4) cell lines are treated with indicated doses of PRT318.
