Segall and coworkers described the in vitro mouse hepatic microsomal metabolism of the alkaloid senecionine (159) (Scheme 34). Several pyrrolizidine alkaloid metabolites were isolated from mouse liver microsomal incubation mixtures and identified (222, 223). Preparative-scale incubations with mouse liver microsomes enabled the isolation of metabolites for mass spectral and H-NMR analysis. Senecic acid (161) was identified by GC-MS comparison with authentic 161. A new metabolite, 19-hydroxysenecionine (160), gave a molecular ion consistent with the addition of one oxygen atom to the senecionine structure. The position to which the new oxygen atom had been added was made evident by the H-NMR spectrum. The three-proton doublet for the methyl group at position 19 of senecionine was absent in the NMR spectrum of the metabolite and was replaced by two signals (one proton each) at 3.99 and 3.61 ppm for a new carbinol methylene functional group. All other H-NMR spectral data were consistent for the structure of 160 as the new metabolite (222).

Pyrrolizidine alkaloids have a wide distribution, but are characteristic of certain genera of the Boraginaceae (e.g. Heliotropium, Cynoglossum, and Symphytum), the Compositae/Asteraceae (e.g. Senecio) and the Leguminosae/Fabaceae (e.g. Crotalaria). The pyrrolizidine bases rarely occur in the free form, but are generally found as esters with rare mono- or di-basic acids, the necic acids. Thus, senecionine (Figure 6.18) from Senecio species is a diester of retronecine with senecic acid. Inspection of the ten-carbon skeleton...
