mouse cxcr2

SCH 563705 是一种可口服且具有高效性的 CXCR2 和 CXCR1 拮抗剂，可用于研究急性呼吸综合征、慢性阻塞性肺病和炎症。

Navarixin (MK-7123) 是一种可口服的 CXCR1和 CXCR2变构拮抗剂，对猕猴 CXCR1的 Kd 值为 41 nM，对大小鼠和猕猴 CXCR2的 Kd 值分别为 0.20、0.20 和 0.08 nM。

AZD8797 (KAND567) 是一种可口服且具有选择性和有效性的人 CX3CR1 变构拮抗剂，对 CX3CR1 和 CXCR2 具有抑制作用，对SARS-CoV-2诱导的神经元损伤有潜在的保护作用，可防止癫痫发作后偏头痛模型大鼠痛觉过敏和小胶质细胞活化的恶化。

CXCR2-IN-2 is a selective, brain penetrant, and orally bioavailable CXCR2 antagonist (IC50=5.2 nM 1 nM in β-arrestin assay CXCR2 Tango assay, respectively). CXCR2-IN-2 displays ~730-fold selectivity over CXCR1 and >1900-fold selectivity over all other chemokine receptors. CXCR2-IN-2 inhibits human whole blood Gro-α induced CD11b expression with an IC50 of 0.04 μM[1]. CXCR2-IN-2 (compound 68) (1-10 mg kg; p.o.; twice daily for 3 days) dose-dependently reduces neutrophil infiltration in vivo in rat and mouse air pouch models[1]. [1]. Lu H, et al.
