Lanraplenib (GS-9876) 是一种高度选择性的口服 SYK 抑制剂 (IC₅₀=9.5 nM) ，用于研究炎症性疾病。Lanraplenib (GS-9876) 通过糖蛋白 VI (GPVI) 受体抑制血小板中的 SYK 活性，而不会延长猴子或人类的出血时间 (BT)。

Lanraplenib (GS-9876) is a highly selective and orally active SYK inhibitor (IC 50 =9.5 nM) in development for the treatment of inflammatory diseases. Lanraplenib (GS-9876) inhibits SYK activity in platelets via the glycoprotein VI (GPVI) receptor without prolonging bleeding time (BT) in monkeys or humans.

Solid

IC50: 9.5 nM (SYK)

Lanraplenib (GS-9876) inhibits anti-IgM stimulated phosphorylation of AKT, BLNK, BTK, ERK, MEK, and PKCδ in human B cells with EC50 values of 24-51 nM. Lanraplenib (GS-9876) inhibits anti-IgM mediated CD69 and CD86 expression on B-cells (EC50=112±10 nM and 164±15 nM, respectively) and anti-IgM /anti-CD40 co-stimulated B cell proliferation (EC50=108±55 nM). In human macrophages, Lanraplenib (GS-9876) inhibits IC-stimulated TNFα and IL-1β release (EC50=121±77 nM and 9±17 nM, respectively).
Lanraplenib (GS-9876) inhibits glycoprotein VI (GPVI)-induced phosphorylation of linker for activation of T cells and phospholipase Cγ2, platelet activation and aggregation in human whole blood, and platelet binding to collagen under arterial flow. has not independently confirmed the accur
