Description | Entospletinib (GS-9973) is an orally bioavailable, selective Syk inhibitor with IC50 of 7.7 nM in a cell-free assay and showed 13- to >1000-fold cellular selectivity for Syk over other kinases(including Jak2, ckit, Flt3, Ret, KDR) as assessed by target protein phosphorylation or functional response. | ||

Targets |
|
||
In vitro | GS-9973 shows good bidirectional permeability across Caco-2 cell monolayers in vitro. In cells, GS-9973 also shows excellent selectivity for Syk, and potently inhibits BCR-mediated activation and proliferation of B-cells as well as immune-complex-stimulated cytokine production in monocytes. [1] The combination of GS-9973 synergistically inhibits CLL cell viability and further disrupts chemokine signaling. [2] |
||
In vivo | GS-9973 (1 mg/kg p.o.) shows moderate to high bioavailability in rat and dog. In a rat collagen-induced arthritis model, GS-9973 (1-10 mg/kg p.o.) significantly inhibits ankle inflammation. Moreover, GS-9973 also shows disease-modifying activity in multiple histological measurements, including inhibition of pannus formation, cartilage damage, bone resorption, and peritosteal bone formation with ED50 ranging from 1.2 to 3.9 mg/kg .
