A synthetic decapeptide, L-pglutamyl-L-histidyl-L-tryptophanyl-L-seryl-L-tyrosyl-glycyl-L-leucyl-L- arginyl-L-prolyl-glycinamide which has the hormonal activities of the luteinizing hormone releasing hormone (LRH) of the hypothalamus gland of mammals is produced by utilizing as the key starting materials, the amino acids, glutamic acid or pyroglutamic acid, histidine, tryptophan, serine, tyrosine, glycine, leucine, arginine, and proline. Synthesis of the decapeptide is accomplished by coupling, in appropriate combinations of appropriate protected forms of the amino acids, and finally deprotecting to yield the amide, L-pglutamyl-L-histidyl-L-tryptophanyl-L-seryl-L-tyrosyl-glycyl-L-leucyl-L- arginyl-L-prolyl-glycinamide.
一种合成的十肽,L-谷氨酰-L-组氨酰-L-色氨酰-L-丝氨酰-L-酪氨酰-甘氨酰-L-亮氨酰-L-精氨酰-L-脯氨酰-甘胺酰,具有哺乳动物下丘脑腺体促黄体激素释放激素(LRH)的激素活性,其关键起始物质为氨基酸谷氨酸或吡二酰谷氨酸,组氨酸,色氨酸,丝氨酸,酪氨酸,甘氨酸,亮氨酸,精氨酸和脯氨酸。通过使用适当保护的氨基酸的适当组合进行耦合,最后去保护得到酰胺,从而完成十肽的合成,即L-谷氨酰-L-组氨酰-L-色氨酰-L-丝氨酰-L-酪氨酰-甘氨酰-L-亮氨酰-L-精氨酰-L-脯氨酰-甘胺酰。
