Description:

WARNING: This product is for research use only, not for human or veterinary use.

Lanraplenib, also known as GS-9876 and GS-SYK, is a tyrosine kinase inhibitor. Lanraplenib blocked the progression of LN-like disease in NZB/W mice. Human in vitro and murine in vivo data suggest that lanraplenib may be efficacious in preventing disease progression in patients with LN at least in part by inhibiting B cell maturation. GS-9876 inhibited SYK activity in platelets via the GPVI receptor without prolonging BT in monkeys or humans. Furthermore, GS-9876 did not increase inhibition of platelet aggregation by NSAIDs in vitro, suggesting that these agents can potentially be combined without increasing bleeding risk in humans.
