GNF-2 is an allosteric inhibitor of Bcr-Abl (IC₅₀ = 267 nM). It is selective for Bcr-Abl over c-Abl and a panel of 63 additional kinases at 10 μM. It inhibits proliferation of Ba/F3 cells (IC₅₀ = 138 nM). GNF-2 (10 μM) reduces viral titers in Vero cells infected with infectious bronchitis virus (IBV), a coronavirus, via inhibition of IBV surface glycoprotein-induced syncytia formation and virus-cell fusion. It inhibits LPS-induced production of nitric oxide (NO) and TNF-α in BV-2 microglia when used at concentrations of 10 and 20 μM. GNF-2 (1 and 10 mg/kg) reduces paw edema and increases the latency to paw withdrawal in a mouse model of inflammatory pain induced by complete Freund’s adjuvant (CFA). It also decreases mechanical and thermal hyperalgesia in a mouse model of diabetic neuropathy induced by streptozotocin (STZ; Item No. 13104).

Bcr-abl Inhibitor is an inhibitor of c-Abl and Bcr-abl activity. It is a COVID19-related research product.

ChEBI: 3-[6-[4-(trifluoromethoxy)anilino]-4-pyrimidinyl]benzamide is a member of pyrimidines.

GNF-2 belongs to a new class of Bcr-abl inhibitors. GNF-2 appears to bind to the myristoyl binding pocket, an allosteric site distant from the active site, stabilizing the inactive form of the kinase. It inhibits Bcr-abl phosphorylation with an IC50 of 267 nM, but does not inhibit a panel of 63 other kinases, including native c-Abl, and shows complete lack of toxicity towards cells not expressing Bcr-Abl. GNF-2 shows great potential for a new class of inhibitor to study Bcr-abl activity and to treat resistant Chronic myelogenous leukemia (CML), which is caused the Bcr-Abl oncoprotein.
