HPLC (336 nm: (a) and (b); 421 nm: (c) and (d)) analysis after incubation of the naphthoquinones with chassis cells. (a): i—Culture control of S. cerevisiae INVSc1; ii—1,4-naphthoquinone; iii—1,4-naphthoquinone incubated with S. cerevisiae INVSc1. (b): i—culture control of E. coli BL21 (DE3); ii—1,4-naphthoquinone; iii—1,4-naphthoquinone incubated with E. coli BL21(DE3). (c): i—culture control of S. cerevisiae INVSc1; ii—juglone; iii—juglone incubated with S. cerevisiae INVSc1. (d): i—culture control of E. coli BL21(DE3); ii—juglone; iii—juglone incubated with E. coli BL21(DE3). (a) Was analyzed using linear gradient of 20–40% (vol/vol) acetonitrile-water (containing 0.1% formic acid) for 30 min and 40–98% for 10 min at a flow rate of 0.9 mL/min, while (b), (c) and (d) were performed at linear gradient of 10–90% for 30 min at 1 mL/min.
