A biologically active fluorescent compound, (-)-7-(2-- dansylaminoethyl)indolactam V(), was synthesized from (-)-indolactam V () in 6 steps together with an inactive fluorescent derivative, (-)-7-(2--dansylaminoethyl)-14--methylindolactam V (). (-)-Indolactam V () exists as two stable conformers in solution at room temperature. The effect of substituents and substitution positions of the indole ring
由(-)-吲哚内酰胺V()分6步合成了具有生物活性的荧光化合物(-)-7-(2--丹酰氨基乙基)吲哚内酰胺V()以及无活性的荧光衍生物(-)-7- (2--腺苷氨基乙基)-14--甲基吲哚内酰胺V()。(-)-Indolactam V()在室温下以两种稳定的构象形式存在于溶液中。详细讨论了吲哚环的取代基和取代位置对(-)-吲哚内酰胺V()这两个构象态的影响。
