Novel stereoisomeric indole compounds of the formula (1), a process for the preparation the same, and use thereof
wherein, Y represents the group
wherein, X represents alkyl group having 1-5 carbon atom(s) (the alkyl group may be substituted with hydroxyl group, carboxyl group, amino group, methylthio group, mercapto group, guanidyl group, imidazolyl group or benzyl group), and R1 and R2 represent each independently hydrogen atom, alkyl group, aralkyl group, cycloalkyl group or aryl group;R represents hydrogen atom, alkyl group, aralkyl group, cycloalkyl group, aryl group, monovalent metal, amine or ammonium; and the symbol ‘*’ represents a position of an asymmetric carbon atom. The above-mentioned compounds can be prepared by condensing tryptophan with a stereoisomeric &agr;-amino acid or carboxylic acid to form an amide form and subjecting or carboxylic acid to form an amide form and subjecting the amide form to oxidative cyclization to form an oxazole ring at once. The compounds exhibit; physiological activities such as inhibitory action against lipid peroxidation, and can be therefore utilized in the form of lipid peroxidation inhibitors containing the same as the active ingredient.
新颖的立体异构
吲哚化合物的
化学式(1),其制备方法及用途,其中,Y代表的是该组,X代表具有1-5个
碳原子的烷基(该烷基可以被羟基、羧基、
氨基、甲
硫基、巯基、
胍基、
咪唑基或
苄基取代),R1和R2各自独立地代表
氢原子、烷基、芳基、
环烷基或芳基;R代表
氢原子、烷基、芳基、
环烷基、芳基、一价
金属、胺或
铵;符号‘*’代表不对称
碳原子的位置。上述化合物可通过将色
氨酸与立体异构的
α-氨基酸或
羧酸缩合形成
酰胺形式,再将
酰胺形式
氧化环化一次形成
噁唑环来制备。这些化合物表现出生理活性,如对脂质过
氧化的抑制作用,因此可以作为含有其作为活性成分的脂质过
氧化
抑制剂而被利用。
