产品描述:
Obeldesivir is an antiviral nucleoside analog and a prodrug form of GS-441524 (Item No. 30469).{72268} It inhibits the replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and SARS-CoV-2 Βeta, Gamma, or Omicron variants in infected Vero E6 cells (EC50s = 1.36, 1.127, 0.349, and 0.106 µM, respectively) with a 50% cytotoxicity concentration (CC50) value of 128 µM. Obeldesivir (250 or 500 mg/kg per day) reduces nucleocapsid guide RNA (gRNA) copy number and small-guide RNA (sgRNA) levels in the lungs of, and decreases lung damage in, a KI-hACE2 mouse model of SARS-CoV-2 infection. It reduces the levels of the spike glycoprotein (S protein), also known as the surface glycoprotein, in the lungs of, as well as decreases particle forming units (PFUs) in the lung tissues, reduces lung and spleen inflammation, and prevents viral infection-induced death in, a K18-hACE2 mouse model of SARS-CoV-2 infection when administered at doses of 100 or 250 mg/kg per day.
