Ustiloxin D, produced by the rice plant pathogen Ustilaginoidea virens, exhibits potent anti-tubulin activity. In order to elucidate the effects of functional groups in ustiloxin D on its activity, several derivatives were synthesized and their anti-tubulin activities were estimated. The N, N-dimethylamino derivative and the 14-O-methyl derivative were inactive (IC50>50 μM). 20-Hydroxymethylated ustiloxin D showed decreased inhibitory activity compared with ustiloxin D.
由水稻病原体绿苗锈菌(Ustilaginoidea virens)产生的乌斯替洛辛D(Ustiloxin D)具有强大的抗微管蛋白活性。为了阐明乌斯替洛辛D中官能团对其活性产生的影响,研究人员合成了几种衍生物并评估了它们的抗微管蛋白活性。N, N-二甲基氨基衍生物和14-O-甲基衍生物不具有活性(IC50>50 μM)。与乌斯替洛辛D相比,20-羟甲基乌斯替洛辛D的抑制活性降低。
