nicotinate were obtained. Fungistatic activity of the compounds was evaluated. Nicotinates 5a–c show significant activity against phytopathogenic fungi: Fusarium culmorum, Phytophthora cactorum, Rhizoctonia solani. The activity of the enantiomerically enriched compounds was comparable to the activity of racemic ones. There was no significant difference in fungistatic activity between the enantiomerically enriched
摘要2-甲基庚基异烟酸酯的同源物和类似物(从链霉菌属物种201中分离得到的新型天然抗真菌和抗菌素):外消旋的2-甲基烷基异烟酸酯4和烟酸酯5,对映异构体富含R和S异构体,2-甲基戊基异烟酸酯和烟酸酯是获得。评价了化合物的抑菌活性。烟酸酯5A - ç表现出对植物病原真菌显著活动:镰刀菌,恶疫霉,水稻纹枯病。对映体富集的化合物的活性与外消旋化合物的活性相当。对映体富集的R和S异构体之间的抑真菌活性没有显着差异。研究的化合物及其草酸盐已被证明对真菌类Ascosphaera apis引起的白垩病具有活性。烟酸盐5a和5b以及草酸盐5a – c对Ascosphaera apis的活性高于草酸本身的活性。对于烟酸2-甲基丁酯5a和烟酸2-甲基戊酯的草酸盐显示出特别高的活性。5b。 图形概要
