| Description | MRS1220, a selective and potent antagonist for the human A3 adenosine receptor (hA3AR) with a dissociation constant (Ki) of 0.59 nM, exhibits therapeutic promise for central nervous system disease research. It effectively diminishes glioblastoma tumor size and inhibits blood vessel formation in vivo. |
| In vitro | MRS 1220 reverses the A3 agonist-induced inhibition of tumor necrosis factor-α formation in the human macrophage U-937 cell line with an IC50 of 0.3 μM[1], and decreases VEGF secretion by approximately 25% in U87MG glioblastoma stem-like cells (GSCs) after 72 hours of hypoxia[2]. |
| In vivo | MRS1220 (0.15 mg/kg; intraperitoneal inoculation) significantly reduces tumor size and blood vessel formation in vivo, exhibiting a strong anti-angiogenic effect[2]. |
