sinalbin A is described. This cruciferous phytoalexin is produced by white mustard (Sinapis alba) after treatment with biotic and abiotic elicitors. In addition, a related metabolite, named sinalbin B, is present in extracts from elicited plants, but not in those from non-elicited controls. Sinalbin B, which was also synthesized, appears to be both a phytoalexin and a biosynthetic precursor of sinalbin
描述了 sinalbin A 的化学结构和合成。这种十字花科植物抗毒素是由白芥菜 (Sinapis alba) 在用生物和非生物诱导剂处理后产生的。此外,一种名为 sinalbin B 的相关代谢物存在于诱导植物的提取物中,但不存在于非诱导对照的提取物中。Sinalbin B 也是合成的,它似乎既是植物抗毒素又是 sinalbin A 的生物合成前体。
