B-Raf IN 2（Cat No.:I045175）is a potent, selective inhibitor of B-Raf, a serine/threonine-protein kinase in the RAS/RAF/MEK/ERK signaling pathway that regulates cell growth and survival. By targeting mutant forms such as B-Raf^V600E, B-Raf IN 2 suppresses aberrant MAPK pathway activation, reducing tumor cell proliferation and promoting apoptosis. It demonstrates strong activity in preclinical cancer models, particularly melanoma and other B-Raf–driven malignancies. B-Raf IN 2 is a valuable research tool for studying oncogenic kinase signaling and holds potential for developing targeted therapies against cancers harboring activating B-Raf mutations.
