(A) Single-agent dose-response curve for TMP; (B) Single-agent dose-response curve for PLU; (C) The interaction landscape of the combinations of TMP and PLU; (D) Synergy scores were calculated by the Bliss independence model and were colored when significant. A detailed description of the various plots is given in Fig 4. Raw data of these experiments can be found in (S2 File). TMP: trimethoprim, PLU: plumbagin.
