生物活性

Peramivir Trihydrate is a trihydrate of the anti-infection agent Peramivir Trihydrate which is a transition-state analogue and a potent, specific influenza viral neuraminidase inhibitor with an IC50 of median 0.09 nM. The IC50 for Peramivir Trihydrate is markedly lower than that for either zanamivir or oseltamivir. Peramivir Trihydrate increases survival in preclinical influenza models, including mouse and ferret models of highly pathogenic avian influenza H5N1. One day of treatment with Peramivir Trihydrate is active, and multiple days of treatment rescues most or all mice with H5N1. Similar data have been obtained in ongoing murine experiments with seasonal influenza A (H1N1)/H274Y. After parenteral administration,Peramivir Trihydrate reaches very high plasma concentrations. Peramivir Trihydrate is not metabolized, and is cleared by the means of renal filtration. It has a long half-life, especially in comparison with other neuraminidase inhibitors. Due to the failure of the metabolism of the antivirus compound Peramivir Trihydrate, as well as its wide distribution and the excretion in the unchanged form in urine, dosing regimens can be adapted easily for patients with renal impairment and for pediatric populations. Peramivir Trihydrate is originally developed by BioCryst Pharmaceuticals. And Peramivir Trihydrate is designed to aim to an antiviral agent. Peramivir Trihydrate has been performed phase III clinical trials for the treatment of influenza.

化学数据

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的K_m系数（3），再除以大鼠的K_m系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
