Leritrelvir (RAY1216) has a drug-target residence time of 104 min[1].
Leritrelvir is covalently attached to the catalytic Cys145 through the α-ketoamide warhead[1].
Leritrelvir (0-1000 nM; 72 h) shows antiviral activities against SARS-CoV-2 wild type ancestral strain and variants[1].
Leritrelvir (RAY1216 (150-600 mg/kg/day; i.g.; 5 days) effectively prolongs survival of SARS-CoV-2 infected mice[1].

Cmax: the maximum observed concentration of the drug collected in bodily material from subjects in a clinical study
Tmax: the time it takes to reach the maximum concentration or time to Cmax
AUC: “Area Under the Curve” and represents the total exposure of the drug experienced by the subject in a clinical study
Cl: total plasma clearance
Vdss: Steady state volume of distribution
T1/2: Half-time is the time it takes for half the drug concentration to be eliminated
oral (F%): Oral bioavailability

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
