indolizidine alkaloid swainsonine, the diablo locoweed (Astragalu oxyphysus) has been found to produce [1,8a-trans]-1-hydroxyindolizidine and [1,8a-trans-1,2-cis]-1,2-dihydroxyindolizidine, known precursors of swainsonine in the fungus Rhizoctonia leguminicola. As in the fungus, [G-3H]-pipecolic acid is incorporated into all three alkaloids. It is proposed that swainsonine biosynthesis in A. oxyphysus occurs
除了有毒的吲哚并立生物碱swainsonine外,还发现了暗黑破坏神草(Astragalu oxyphysus)会产生[1,8a-反式] -1-羟基吲哚并立核苷和[1,8a-反式-1,2-顺式] -1,2 -dihydroxyindolizidine,在真菌Rhizoctonia leguminicola中swainsonine的已知前体。如在真菌中一样,[G- 3 H]-哌酸被掺入所有三种生物碱中。有人提出,在氧化菌中swainsonine的生物合成是通过与真菌途径非常相似的途径进行的。
