产品描述

Leritrelvir (RAY1216) is an orally active SARS-CoV-2 main protease slow-tight inhibitor with a Ki of 8.6 nM.

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
