Abstract The structure of a new gibberellin-like antheridiogen from gametophytes of the fern Lygodium circinnatum has been confirmed as the methyl ester of 12α-hydroxy gibberellin A73 (GA117) by synthesis of an authentic sample from the 17-nor-16-one derived from GA73. Comparative bioassays of the synthetic compound as an antheridium inducing substance in Lygodium japonicum showed that it is highly
摘要 通过从 17-nor-16-one 衍生的真实样品合成真实样品,来自蕨类植物海参配子体的一种新的类
赤霉素类花药结构已被证实为 12α-羟基
赤霉素 A73 (GA117) 的甲酯。 GA73。合成化合物作为海参中花药诱导物质的比较
生物测定表明,它是高效的,具有皮摩尔范围的活性,并且比 12β-差向异构体 (GA96) 的活性高得多。
