| 产品描述 | Givosiran (ALN-AS1) is a small interfering RNA compound that selectively targets hepatic aminolevulinate synthase 1 (ALAS1) mRNA, leading to efficient downregulation of ALAS1 expression and consequent inhibition of neurotoxic δ-aminolevulinic acid and porphobilinogen accumulation. Givosiran provides a mechanism-driven research tool with significant relevance for studying metabolic dysregulation and therapeutic intervention strategies in acute intermittent porphyria. |
| 体外活性 | Givosiran is conjugated to a trivalent N-acetylgalactosamine ligand, which binds specifically to the asialoglycoprotein receptor, enabling targeted delivery to hepatocytes[2]. |
| 体内活性 | 在大鼠模型中,单次皮下注射 Givosiran (10 mg/kg) 降低了肝组织和血清中的 ALAS1 mRNA 水平。在苯巴比妥诱导的急性间歇性卟啉症 (AIP) 大鼠模型中,3 mg/kg 的方案(每周两次,持续 3 周)防止了 ALAS1 的升高和毒性代谢物的积累。在 T1/T2 AIP 小鼠中,单剂量 Givosiran (20 mg/kg) 对 ALAS1 的抑制速度快于血红素 (Hemin) 处理。对食蟹猴的研究 (1-10 mg/kg) 显示,血清和尿液中 ALAS1 呈剂量依赖性下降,且在 8 周给药期结束后该效应具有可逆性 [2]。 |
