Fig. 6

a Body weight change of C57BL/6 mouse treated with 20 mg/kg NK01-63 or water vehicle via intraperitoneal (IP) or oral (PO) dose for 14 consecutive days on an in vivo toxicity study. Data are plotted as the mean ± s.d., n = 10 biological replicates. Two-tailed t test were performed on weight of 14 days post initial treatment. Pns of IP = 0.07, Pns of PO = 0.68. b, c Molar concentration of NK01-63 in plasma or lung of C57BL/6 mouse 0 h, 2 h, 4 h, 8 h, or 24 h after treatment with 20 mg/kg NK01-63 via intraperitoneal (IP) or oral (PO) dose. Data are plotted as the mean ± s.d., n = 8 biological replicates. EC90 value of NK01-63 is from Caco-2 cell-based SARS-CoV-2 antiviral assay. Source data are provided as a Source Data file.
