The chemical modification of validamycin A was examined. One of the synthetic validamy-cin analogs, N[(1S)-(1, 4, 6/5)-4, 5, 6-trihydroxy-3-hydroxymethyl-2-cyclohexenyl] [O-β-2-amino-2-deoxy-D-glucopyranosyl-(1→3)-(1S)-(1, 2, 4/3, 5) -2, 3, 4- trihydroxy-5-hydroxymethyl-cyclohexy] amine monohydrochloride had almost the same activity against the sheath blight of rice plants as that of validamycin A. Partial synthesis of validamycin A was also examined.
检查了井冈霉素 A 的化学修饰。一种合成的有效霉素类似物,N[(1S)-(1, 4, 6/5)-4, 5, 6-三羟基-3-羟甲基-2-环己烯基] [O-β-2-氨基- 2-脱氧-D-吡喃葡萄糖基-(1→3)-(1S)-(1, 2, 4/3, 5) -2, 3, 4-三羟基-5-羟甲基-环己基]胺单盐酸盐几乎相同对抗水稻纹枯病的活性与井冈霉素A的活性相同。还检测了井冈霉素A的部分合成。
