Phytoalexins play a significant role in the defense response of plants. These secondary metabolites, which are synthesized de novo in response to diverse forms of stress, including fungal infection, are part of the plants' chemical and biochemical defense mechanisms. Phytoalexins from crucifers are structurally and biogenetically related, but display significantly different biological activities. Here, we review work reporting the chemical structures, synthesis, biosynthesis and metabolism of cruciferous phytoalexins, as well as their biological activity towards different microorganisms.
植保素在植物的防御反应中发挥着重要作用。这些次生代谢产物是在应对包括真菌感染在内的多种形式的胁迫时重新合成的，是植物化学和生化防御机制的一部分。十字花科植物的植保素在结构和生源上相关，但具有显著不同的生物活性。在这里，我们综述了有关十字花科植物植保素的化学结构、合成、生物合成和代谢，以及它们对不同微生物的生物活性的研究报道。
