Extended Data Fig. 6: Conversion of prestrychnine 9 to strychnine 10 and isostrychnine 11.

From: Biosynthesis of strychnine

Extended Data Fig. 6

a. Reaction of the conversion. b. Extracted ion chromatograms for prestrychnine 9 (m/z [M+H]+ = 397.1758 ± 0.05, left) and strychnine 10 and isostrychnine 11 (m/z [M+H]+ = 335.1754 ± 0.05, right). These experiments were repeated three times with similar results. c. MS/MS (20 to 50 eV) spectra of generated m/z [M+H]+ 335.1754 (strychnine 10 and isostrychnine 11, blue) compared to standards (red).
