The octacosapeptide corresponding to the entire amino acid sequence of thymosin α1 was synthesized using the catalytic hydrogenation procedure at the final deprotection step. The depressed E-rosette forming capacity of lymphocytes caused by a serum factor from a patient in the active stage of MCNS was significantly restored when the lymphocytes were incubated with thymosin α1. The relative potency of the decapeptide fragment (positions 19-28) was 1.04 and that of the pentadecapeptide fragment (positions 14-28) was 9.83 based on synthetic thymosin α1 (100.00) as a standard.
在最后的脱保护步骤中使用催化氢化程序合成了与胸腺肽α1的整个氨基酸序列相对应的八肽。当淋巴细胞与胸腺肽α1一起孵育时,处于MCNS活动期患者的血清因子所导致的淋巴细胞E-玫瑰花瓣形成能力的降低得到了明显的恢复。以合成胸腺肽α1(100.00)为标准,十肽片段(19-28位)的相对效力为1.04,十胜肽片段(14-28位)的相对效力为9.83。
