چکیده
Biosynthesis, 2H-NMR, Phytoalexin, Pisatin, Pterocarpan 2H-NMR analysis of the 6a-hydroxypterocarpan phytoalexin pisatin derived in CuCl2-treated pea [Pisum sativum) pods from [6,1 la -2H2]maackiain has demonstrated the retention of all 2H labels. This establishes that no pterocarp-6a-ene or pterocarp-6-ene interm ediate is involved, and thus confirms a direct 6a-hydroxylation mechanism for the biosynthesis of 6a-hydroxypterocarpans from pterocarpans.

Role of oxygenases in pisatin biosynthesis and in the fungal degradation of maackiain.
Some isolates of the plant pathogen Nectria haematococca detoxify the isoflavonoid phytoalexin (-)maackiain by hydroxylation at carbon 6a. Precursor feeding studies strongly suggest that the penultimate step in (+)pisatin biosynthesis by Pisum sativum is 6a-hydroxylation of (+)maackiain. We have used (18)O labeling to test the involvement of oxygenases in these two reactions. When fungal metabo...
متن کاملPterocarpans from Derris laxiflora.
Six compounds were isolated from Derris laxiflora Benth., including two new pterocarpans, 7,6'-dihydroxy-3'-methoxypterocarpan (1) and derrispisatin (2), as well as four known ones, lespedezol D, (3), secundiflorol 1 (4), 6a-hydroxymaackiain (5) and pisatin (6). The structures of these compounds were determined by analysis of their spectroscopic data.

Leguminosae, Erythrina, Pterocarpans, Isoflavans, Phytoalexins Two new phytoalexins isolated from the fungus-inoculated leaflets of Erythrina sandwicensis have been identified as (—)-6aS; 11 aS-3,6 a,9-trihydroxy-10-isopentenylpterocarpan (sandwicarpin) and (—)-6a/?; 11 a^-3-hydroxy-9-methoxy-10-isopentenylpterocaipan (sandwicensin). These compounds co-occur with several known pterocarpan (deme...
متن کاملSynthesis, optical resolution, absolute configuration, and osteogenic activity of cis-pterocarpans.
A convenient synthesis of natural and synthetic pterocarpans was achieved in three steps. Optical resolution of the respective enantiomers was accomplished by analytical and semi-preparative HPLC on a chiral stationary phase. For medicarpin and its synthetic derivative 9-demethoxymedicarpin, the absolute configuration was confirmed by a combination of experimental LC-ECD coupling and quantum-ch...
متن کاملMetabolism of Steroids in the Foetus BIOSYNTHESIS OF 60c-HYDROXYTESTOSTERONE IN THE HUMAN FOETAL LIVER
Schubert, Wehrberger & Frankenberg (1964) first isolated and identified 6a-hydroxytestosterone as a metabolite in human urine after intravenous administration oftestosterone to adult women. The tissue site of O6c-hydroxylation was unknown, and it could not be excluded that the metabolite had arisen by epimerization of 6fl-hydroxytestosterone. Recently we demonstrated that testosterone is hydrox...
