产品介绍
SX-517 是一种靶向CXCR2/1的双重拮抗剂，并且分子中含有硼酸。SX-517 还抑制 CXCL-1 诱导的 Ca2+通量 (IC50=38 nM)，拮抗 CXCL-8 诱导的 [(35)S]GTPγS 结合作用 (IC50=60 nM)，和ERK1/2磷酸化。SX-517 在人源多形核细胞 (PMN) 和小鼠模型中均具有显著的炎症抑制能力。
生物活性

SX-517 is a dualCXCR2/1antagonist, containing boronic acid. SX-517 inhibits CXCL1-induced Ca2+flux (IC50=38 nM), and antagonizes CXCL8-induced [(35)S]GTPγS binding (IC50=60 nM) andERK1/2phosphorylation. SX-517 has significant ability for inflammation suppression, in both humanized polymorphonuclear (PMN) cells and in murine model[1][2].

体外研究
(In Vitro)

SX-517 (compound 7) (0.1 nM-0.1 mM; 60 min) potently inhibits [35S]GTPγS binding induced by 10 nM CXCL8 with an IC50 of 60 nM[1].
SX-517 (10 μM; 60 min) has inhibitory effect on the cell surface expression of CXCR2 in HEK293 cells[1].
SX-517 (10 μM; 0-30 min) blocks CXCR2-mediated phosphorylation of ERK1/2 in HEK293 cells[1].

Western Blot Analysis[1]

Cell Line:HEK293 cells
Concentration:10 μM; with or without 100 ng/mL CXCL-8
Incubation Time:0, 5, 15, 30 min
Result:Completely blocked CXCL-8-induced phosphorylation of ERK1/2 by 30 min.
体内研究
(In Vivo)

SX-517 (compound 7) (0.2 mg/kg; iv; single dose) significantly inhibits inflammation in an in vivo murine model[1].

Animal Model:Male CD1 SWISS mice with an air-pouch on the backs (10-15 week old)[1]
Dosage:0.02 mg/kg, 0.2 mg/kg
Administration:Intravenous injection; single dose
Result:Significant reduction in cell count in the pouches of treated animals compared to the positive control cohort.
