  Occurrence and origin of ent-17-hydroxykaur-15-ene and ent-17-hydroxykaur-15-en-19-oic acid in shoots of Zea mays

  摘要：

  Previously unidentified metabolites of ent-kaur-16-ene and ent-kaur-16-en-19-oic acid in shoots of maize are identified, respectively, as ent-17-hydroxykaur-15-ene and ent-17-hydroxykaur-15-en-19-oic acid by GC-MS comparison with authentic samples. The production of the two latter compounds from the first two substances is analogous to the metabolism of gibberellin A(5) to gibberellin A(3) and provides two further examples, in plants, of hydroxylation at a double bond with rearrangement of the double bond.

  This paper reports on the syntheses and spectrometric characterisation of eleven novel ent-kaurane diterpenoids, including a complete set of H-1, C-13 NMR and crystallographic data for two novel ent-kaurane diepoxides. Moreover, the antineoplastic cytotoxicity for kaurenoic acid and the majority of ent-kaurane derivatives were assessed in vitro against a panel of fourteen cancer cell lines, of which allylic alcohols were shown to be the most active compounds. The good in vitro antimalarial activity and the higher selectivity index values observed for some ent-kaurane epoxides against the chloroquine-resistant W2 clone of Plasmodium falciparum indicate that this class of natural products may provide new hits for the development of antimalarial drugs.
