  2. Article: Metabolism of Tritiated Gibberellins in d-5 Dward Maize: II. [H]Gibberellin A(1), [H]Gibberellin A(3), and Related Compounds.

    Abstract: After 30 minutes of incubation of young leaf sections of d-5 maize (Zea mays L.) in [(3)H ... 3)H]GA(1) and [(3)H]GA(3), with their identical D ring structures, were converted to [(3)H]GA(1)-X ... type compounds; [(3)H]-ketoGA(1) and [(3)H]tetrahydroGA(3), with modified D rings, were not converted ...

    Abstract After 30 minutes of incubation of young leaf sections of d-5 maize (Zea mays L.) in [(3)H]gibberellin A(1) ([(3)H]GA(1)), the metabolite [(3)H]GA(8) was present in significant amounts, with a second metabolite, [(3)H]GA(8)-glucose ([(3)H]GA(8)-glu), appearing soon after. A third [(3)H]GA(1) metabolite, the polar uncharacterized conjugate [(3)H]GA(1)-X, took more than 1 hour to appear. The protein synthesis inhibitor cycloheximide inhibited the production of all [(3)H]GA(1) metabolites, indicating a possible protein synthesis requirement for [(3)H]GA(1) metabolism.By preincubating leaf sections in unlabeled GA(1) before exposure to [(3)H]GA(1) or by reducing the specific radioactivity of the [(3)H]GA(1) supplied, it was possible to reduce greatly the conversion of radioactive GA(1) to [(3)H]GA(8)-glu, without affecting conversion to [(3)H]GA(1)-X. Increasing the molar concentration of the [(3)H]GA(1) fed greatly increased the molar yield of [(3)H]GA(1)-X, whereas the molar yields of [(3)H]GA(8) and [(3)H]GA(8)-glu were much less affected.The principal metabolite of [(3)H]GA(3) was a very polar compound having chromatographic properties similar to those of the conjugate [(3)H]GA(1)-X produced from [(3)H]GA(1). The naturally occurring GAs [(3)H]GA(1), [(3)H]GA(3), and [(3)H]tetrahydroGA(3) were metabolized to a much greater extent than were the artifical derivatives [(3)H]ketoGA(1), [(3)H]GA(1)-methyl ester, and [(3)H]pseudoGA(1). Only [(3)H]GA(1) and [(3)H]GA(3), with their identical D ring structures, were converted to [(3)H]GA(1)-X type compounds; [(3)H]-ketoGA(1) and [(3)H]tetrahydroGA(3), with modified D rings, were not converted to this type of conjugate.

  3. Article ; Online: Isolation and characterization of diastereomers of discorhabdins H and K and assignment of absolute configuration to discorhabdins D, N, Q, S, T, and U.

    Abstract: ... assigned to the known metabolites discorhabdins H, D, 2-hydroxy-D, N, and Q by comparison of ECD spectra ... waters has led to the characterization of a new diastereomer of discorhabdin H, named discorhabdin H2 ...

    Abstract Investigations of four different sponge populations of Latrunculia species collected in New Zealand waters has led to the characterization of a new diastereomer of discorhabdin H, named discorhabdin H2, confirmation of the structure of discorhabdin K ((+)-7), and presentation of a new diastereomer, discorhabdin K2 ((-)-8). In each case the structures were established by extensive NMR and MS studies and the absolute configurations interrogated by electronic circular dichroism (ECD). Absolute configurations were assigned to the known metabolites discorhabdins H, D, 2-hydroxy-D, N, and Q by comparison of ECD spectra with those recorded for discorhabdin alkaloids of defined absolute configuration, while the configurations of discorhabdins S, T, and U were assigned by semisynthesis from (+)-(6S,8S)-discorhabdin B.
