生物活性

AMY109 is an anti-human interleukin-8 (IL-8) monoclonal antibody, with IC50 values of 0.14 μg/mL and 0.37 μg/mL against human IL-8, a Ka of 36.8 pM for human IL-8, and a Ka of 380 pM for cynomolgus monkey IL-8.\nAMY109 binds to human and cynomolgus monkey IL-8 in a pH-dependent manner, inhibits IL-8-mediated activation of CXCR1 and CXCR2, and blocks the downstream biological activities of IL-8. AMY109 inhibits neutrophil recruitment to endometriotic lesions and suppresses monocyte chemoattractant protein-1 production by neutrophils. AMY109 is applicable to research related to endometriosis[1].

体外研究
(In Vitro)

AMY109 (pH 7.4; pH 5.8) 对人源 IL-8 表现出高结合亲和力,在中性条件下对食蟹猴 IL-8 表现出较弱但可检测到的结合亲和力,且在内涵体 pH 下会以 pH 依赖的方式与人源 IL-8 解离[1]
AMY109 可在基于细胞的实验中强效中和 IL-8 依赖的 CXCR1CXCR2 活化[1]
AMY109 (600 ng/mL IL-8) 可有效抑制 IL-8 诱导的人食蟹猴中性粒细胞趋化作用[1]
AMY109 可抑制 IL-8 诱导的人中性粒细胞迁移以及 IL-8 刺激人中性粒细胞产生 MCP-1[1]

体内研究
(In Vivo)

AMY109 (2-10 mg/kg; subcutaneous injection; every 4 weeks; 6 months) 可稳定疾病进展、缩小结节病灶体积、诱导子宫内膜异位病灶发生萎缩性改变、减少纤维化,并降低手术诱导子宫内膜异位症的食蟹猴的术后粘连[1]

Animal Model: Macaca fascicularis (female, reproductive age 8 to 14 years old, surgically induced endometriosis)[1]
Dosage: 2 mg/kg (maintenance dose; preceded by a 3 mg/kg loading dose); 10 mg/kg
Administration: subcutaneous injection; every 4 weeks; 6 months
Result: Maintained modified r-ASRM score stable, while it significantly increased in vehicle-treated monkeys.
Reduced relative volume of nodular lesions.
Induced atrophy of endometrial epithelium in 55% of evaluable sites (2 mg/kg) and 54% of evaluable sites (10 mg/kg).
Induced atrophy/decreased stromal cells in 33% of evaluable sites (2 mg/kg) and 60% of evaluable sites (10 mg/kg).
Decreased fibrotic interstitium in 34% of evaluable sites (2 mg/kg) and 61% of evaluable sites (10 mg/kg).
Reduced hemosiderin deposition compared to vehicle.
Produced marked reduction in postsurgical incision adhesions in 6 of 7 monkeys treated with 10 mg/kg.
Achieved greater lesion volume reduction in monkeys without antidrug antibodies (ADAs) than those with ADAs.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
