Carboline alkaloids are a class of important heterocyclic natural products, which usually present extensive bioactivities. During the course of our research for active compounds from natural products, the pityriacitrin and pityriacitrin B belonged carboline alkaloids have been isolated from a Chinese Burkholderia sp. NBF227, which indicated potential antifungal activities. So, in order to develop these
咔啉生物碱是一类重要的杂环天然产物,通常具有广泛的生物活性。在我们对天然产物活性化合物的研究过程中,我们从一种中国伯克霍尔德氏菌中分离出了属于咔啉生物碱的糠秕子苷和糠秕子苷 B。NBF227,表明潜在的抗真菌活性。因此,为了开发这些咔啉类生物碱作为潜在的杀菌剂,研究了一系列糠秕子苷衍生物对辣椒疫霉、核盘菌、灰霉病和立枯丝核菌的抗真菌活性,结果表明化合物4、图10和19显示出广谱抗真菌活性。此外,体内生物测定还表明,化合物4和10可以保护辣椒叶和葡萄果实免受P的感染。辣椒和B . 灰霉病,分别。还探讨了这些化合物的抗真菌作用的可能机制。
