Product Description

GNE-495 is a novel, potent and selective MAP4K4(mitogen-activated protein kinase kinase kinase kinase 4) inhibitor with anIC50of 3.7 nM. In order to study the function of mitogen-activated protein kinase kinase kinase kinase 4 (MAP4K4 in short) in various disease contexts, potent inhibitors had to be found. For illuminating the potential for therapeutic intervention, compounds that can be used to conduct such studies in vivo would be especially important. An advanced compound 13 (GNE-495) that showed excellent potency and good PK was created through a structure-based design effort combined with property-guided optimization aimed at reducing the ability of the inhibitors to cross into the CNS. It was then used to demonstrate in vivo efficacy in a retinal angiogenesis model, recapitulating effects that were seen in the inducible Map4k4 knockout mice.

Biological Activity I Assay Protocols (From Reference)

Targets	MAP4K4 (IC50 = 3.7 nM)
ln Vitro	GNE-495 is a strong MAP4K4 inhibitor that works well to promote angiogenesis. GNE-495 exhibits minimum body stability, permeability, efficient ideal cellular equilibrium, and MAP4K4 adsorption [1].
ln Vivo	High doses of GNE-495—25 and 50 mg/kg—were given intraperitoneally to newborn mouse pups. In every species examined, GNE-495 demonstrates favorable internal characteristics, including low clearance, moderate terminal half-phase decay, and appropriate leverage levels (F=37–47%) [1].
Animal Protocol	Rats, Mice and Pups For the brain cassette study, three male Sprague-Dawley (SD) rats receive an intravenous (IV) bolus dose of six test substances (for example, GNE-495; 0.5 mg/kg). GNE-495 is injected intravenously in bolus doses of 1 mg/kg in female CD-1 mice for the mouse PK study. GNE-495 (5 mg/kg) is additionally injected intravenously (PO) into female CD-1 mice. The rat brain cassette PK is dosed at 2 mL/kg, and all other doses are administered at 5 mL/kg. Water and food are available to animals at all times, and they are not fasted before receiving a dose. Three blood samples (~60 μL) are taken from each mouse up to either 9 or 24 hours after the compound of interest is given. This is done using a serial sampling method, and it involves taking three blood samples from each mouse. After being mixed with K2EDTA and placed on ice or in a cold Kryorack immediately after collection, the blood is then centrifuged to separate the plasma. Blood samples are centrifuged for 10–15 minutes at 4°C while being spun at a speed of 1000-2000× g within an hour of being drawn. This process yields the plasma. The plasma samples are stored at -70 to -80°C until analysis. For neonate PK, 3-day-old CD1 pups are injected with 25 mg/kg and 50 mg/kg GNE-495. Blood samples are taken intraperitoneally at the times specified, retinas are taken one hour after the dose, snap frozen in liquid nitrogen, and kept at -80°C until analysis. The concentrations of plasma and retinal lysate are assessed using LC/MS/MS.
