Biological Activity

CD40 |
R-7050 (TNF-α Antagonist III) is a potent and fully reversible hit with greater selectivity toward TNFα. In TNFα-induced? intercellular adhesion molecule 1 (ICAM-1)? expression, R-7050 inhibition potency (EC50=0.63 μM) is 2- to 3-fold greater than EC50 for IL-1β-induced ICAM-1 expression (EC50=1.45 2 μM). R-7050 inhibits phosphorylation of both the JNK pathway (MKK4, JNKs, and ATF2) and p38 pathway (MKK3/6, p38, and MAPKAP2)[1].
R-7050 is a cell-permeable triazoloquinoxaline compound that selectively inhibits TNF-α induced cellular signaling. Unlike biologic TNF inhibitors (e.g. Infliximab, Etanercept, Adalimumab) that directly bind TNF-α and function as decoy receptors, R-7050 does not affect binding of TNF-α to TNFR. In contrast, R-7050 selectively inhibits the association of TNFR with intracellular adaptor molecules (e.g. TRADD, RIP), limits receptor internalization, and prevents subsequent cellular responses after TNF-α binding[2].

Protocol
Mice[2]
A mouse collagenase model of ICH is utilized. Briefly, male CD-1 mice (8-10 weeks old) are placed into a stereotactic frame and a 0.5 mm diameter burr hole is drilled over the parietal cortex, 2.2 mm lateral to the bregma. A 26-gauge Hamilton syringe, loaded with 0.04 U of bacterial type IV collagenase in 0.5 μL saline, is lowered 3 mm deep from the skull surface directly into the left striatum. The syringe is depressed at a rate of 450 nL/min and left in place for several minutes after the procedure to prevent solution reflux and excess diffusion. Sham animals undergo the same surgical procedure, except that saline is stereotactically injected rather than collagenase. After the syringe is removed, bone wax is used to close the burr hole, the incision is surgically stapled, and mice are kept warm until recovery of the righting reflex. R-7050 (6-18 mg/kg) is administered via intraperitoneal route at the time of injury or up to 2 h post-ICH[2].
