Ziresovir AK0529; RO-0529

产品介绍 Ziresovir (AK0529; RO-0529) 是一种口服有效的,选择性呼吸道合胞病毒 (RSV) 融合 (F) 蛋白 (RSV F) 抑制剂。 Ziresovir 显示抗 RSV 活性 (EC50=3 nM), 并具有药代动力学表现。
生物活性

Ziresovir (AK0529;RO-0529) is a potent, selective, and orally bioavailable respiratory syncytial virus (RSV) fusion (F) protein (RSV F) protein inhibitor. Ziresovir shows anti-RSV activity (EC50=3 nM) and highlights pharmacokinetics in animal species.

体外研究

Ziresovir shows different efficacy in Wild Type (WT) and Mutant Strains RSV with EC50/EC90 values (μM) of 0.003/0.005 (WT), 2.1/10.0 (D486N), and >10/>10 (D489A), respectively.
RO-0529 (100 nM; 4 d) inhibits RSV F protein-induced cell–cell fusion process, and suppresses the syncytia formation induced by the RSV F protein.

体内研究

Ziresovir (12.5 mg/kg, 50 mg/kg; p.o.; twice daily; 4 d) results reduction of RSV titer in mouse lung.
Ziresovir (10 mg/kg; p.o.; single dose) exhibits good oral exposure and bioavailability with F(%) of 32% in male Wistar-Han rats.
Ziresovir (150 mg/kg; p.o.; single dose) demonstrates a high tissue distribution to lung than plasma in CD-1 Mice.

Animal Model: Female BALB/c mice infected by RSV
Dosage: 12.5 mg/kg, 50 mg/kg
Administration: Oral gavage; twice daily; 4 days
Result: Resulted >1 log unit of viral titer reduction in the lung of infected mice at the dose level as low as 12.5 mg/kg. 
Reduced viral titer to 1.9 log units compared to vehicle at 50 mg/kg dose.
