Substituted 3-[2-(diethoxyphosphoryl)propyl]oxazolo[4,5-b]pyridine-2(3H)-ones were obtained by functionalization at 6-position with various substituents (aryl, vinyl, carbonyl chains) via reactions catalysed with palladium. We found that these new fosmidomycin analogues inhibited the accumulation of ajmalicine, a marker of monoterpenoid indole alkaloids production in plant cells. Some of them have
取代的 3-[2-(二乙氧基磷酰基)丙基]恶唑并[4,5-b]吡啶-2(3H)-酮是通过在6-位用各种取代基(芳基、乙烯基、羰基链)通过催化反应获得的钯。我们发现这些新的 fosmidomycin 类似物抑制了 ajmalicine 的积累,ajmalicine 是植物细胞中单萜吲哚生物碱产生的标志物。其中一些具有比磷米霉素更大的抑制作用,并且在100 microM的浓度下完全抑制生物碱的积累。
