The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) have been assessed as measures of drug‐related hepatotoxicity.[73] The results suggested that O‐Mit has no impact on IC‐21 cell proliferation (Figure S9A, Supporting Information) and caused no significant liver damage in ALI mice when more than 20‐fold higher doses than the minimum dose that gave a therapeutic effect (Figure S9B, Supporting Information). Here, GPT is linked to acute respiratory distress syndrome.
