AT-9010 tetrasodium, a triphosphate active metabolite of AT-527, is a potent inhibitor of NiRAN (a function essential for viral replication). AT-9010 tetrasodium can inhibit SARS-CoV-2 replication[1].
Substantial levels of the active triphosphate metabolite AT-9010 are formed in normal human bronchial and nasal epithelial cells incubated with 10 µM AT-511 (698 µM and 236 µM, respectively), with a half-life of at least 38 hours[1].
