(A) The screening of ambroxol’s potential protein targets in human. Details of the discovery workflow are described in the Methods section. (B) PPI network of the intersected targets. The interactions were discovered with a medium confidence rate of 0.4. (C) GO enrichment results of potential targets of ambroxol. The top 15 significant themes with adj. P<0.05 were shown here. (D) KEGG enrichment results of potential targets of ambroxol. The top 15 significant themes with adj. P<0.05 were shown here.
