| Target | TNFR[1] |
| In Vitro | Lenercept (TNFR-IgG) 在放线菌素 D (HY-17559) 处理的小鼠 L-M 细胞中阻断 TNF-α 和 TNF-β 的细胞溶解作用，IC50 分别为 0.5 μg/mL 和 1.5 μg/mL[2]。 |
| In Vivo | Lenercept (Ro 45-2081) 抑制 Sephadex 诱导的大鼠肺损伤[1]。 Lenercept (TNFR-IgG; 0.8-20 μg/mouse; i.v.; once) 当内毒素激发之前或之后不久给药时，可以预防或显著延迟内毒素诱导的小鼠致死率[2]。 Animal Model: Male Sprague-Dawley rats[1] Dosage: 1 and 3 mg/kg Administration: Intraperitoneal injection, 1 h before administration of Sephadex for the 24 h study or 1 h before and at 24 and 48 h after Sephadex for the 72 h study Result: Inhibited the neutrophilia at 24 h after Sephadex. At 72 h after Sephadex, significantly reduced the neutrophil influx into bronchoalveolar lavage fluid (BALF) but had no inhibitory effect on eosinophil number. Animal Model: 6- to 8-week-old female BALB/c mice, septic shock model[2] Dosage: 0.8, 4 or 20 μg/mouse Administration: IV, single dose Result: Injection 0.5 h prior to Salmonella abortus-derived endotoxin (LD100 dose) administration prevented lethality at a dose of 20 μg per mouse and provided partial protection at lower doses. Injection of 10 μg per mouse provided significant protection 0.5 h before, 0.5 h after, or 1 h after endotoxin injection but little protection 2 h after endotoxin injection. |
