The synthesis is described of analogues of L-tryptophyl-L-methionyl-L-aspartyl-L-phenylalanine amide (the C-terminal sequence of the gastrins), and its N-benzyloxycarbonyl or N-t-butoxycarbonyl derivatives, wherein the tryptophyl residue has undergone replacement by glycyl, histidyl, lysyl, phenylalanyl, tyrosyl, 4-, 5- or 6-methyltryptophyl, Nα-methyltryptophyl, or 2- or 5-hydroxytryptophyl residues
描述了L-色氨酸-L-甲硫酰基-L-天冬氨酰-L-苯丙氨酸酰胺(胃泌素的C-末端序列)及其N-苄氧羰基或N-叔丁氧羰基衍生物的类似物的合成,其中残余物具有由甘氨酰,组氨酰,赖氨酰,苯丙氨酰基,酪氨酰基经历更换,4-,5-或6- methyltryptophyl,ñ α -methyltryptophyl,或2-或5- hydroxytryptophyl残基,或以各种其它方式已被修改。
