(A) Chemical structure of UA and potassium usnate (KU). (B–D) Quantitative LC-MS/MS analysis of usnate in tumor tissues (B), liver tissues (C), and plasma (D) in a CT26 syngeneic mouse tumor xenograft model after oral administration of UA or KU. Results are reported as the mean ± standard error of the mean. ***P < 0.001.
