Naporafenib HCl

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

MedKoo CAT#: 206498

CAS#: LXH254 HCl

Description: Naporafenib, also known as LXH254, is an orally available inhibitor of all members of the serine/threonine protein kinase Raf family, with potential antineoplastic activity. Upon administration, pan-RAF inhibitor LXH254 binds to Raf proteins and inhibits Raf-mediated signal transduction pathways. This inhibits proliferation of Raf-overexpressing tumor cells. Raf protein kinases are critical enzymes in the Ras/Raf/MEK/ERK signaling pathway and are upregulated in a variety of cancer cell types..
