Description	R-7050 (TNF-α Antagonist III), a tumor necrosis factor receptor (TNFR) antagonist, exhibits heightened selectivity for TNFα.
In vitro	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].
In vivo	Administered at doses of 6 mg/kg, R-7050 significantly attenuates Evans blue extravasation in brain tissue to 28.7±5.9 μg and 30.3±1.9 μg when given 0.5 hours or 2 hours after induced intracerebral hemorrhage (ICH), respectively, presenting statistical significance (p<0.05 and p<0.01 vs ICH, respectively) and comparability to sham-operated controls. Concurrently, brain water content, indicative of brain edema, increases markedly from 75.6±0.3% in sham to 81.5±0.5% post-ICH (p<0.05 vs. sham). Doses of R-7050 (6, 12, or 18 mg/kg) effectively reduce the brain water content to 78.5±0.3%, 78.3±0.3%, and 79.3±0.5%, respectively, each significantly against ICH (p<0.05) and with no significant difference among the dosages. However, a notable decrease in general activity/locomotion is observed with the highest dose (18 mg/kg). R-7050, at a 6 mg/kg dosage, also significantly mitigates the increase in brain water content post-ICH to levels akin to those in sham-operated mice (p<0.05 vs ICH and not significantly different from sham), demonstrating its potential in reducing both brain edema and permeability post-ICH when administered timely.
