| 中文摘要: |
| 目的采用多肽固相合成法合成蓝贻贝抗凝肽MEAP(Blue mussel Mytilus edulis anticoagulant peptide),初步研究其抗凝活性。方法 以2-CTC树脂为载体, Fmoc保护氨基酸为原料,按照蓝贻贝抗凝肽的序列从C端向N端逐步偶联氨基酸,裂解后得到粗肽,经半制备液相纯化后测定精肽的凝血酶时间(TT)、活化的部分凝血活酶时间(APTT)、凝血酶原时间(PT)。结果 合成的蓝贻贝抗凝肽粗品的纯度为65.5%,经半制备纯化后的精肽纯度为95.5%；抗凝活性实验显示APTT、TT具有显著的延时作用(P<0.01)。结论 固相合成的蓝贻贝抗凝肽具有抗凝活性。 |
| English Summary: |
| Purpose To prepare blue mussel Mytilus edulis anticoagulant peptide (MEAP) by using solid phase peptide synthesis method and to preliminary study its anticoagulant activity. Methods MEAP was successfully synthesized from its C terminal to N terminal according to its peptide sequence by using 2-CTC Resin as the solid supporter and Fmoc-amino acids as raw materials. The crude peptide was cleaved from the resin and purified by semi-prepare RP-HPLC. The thrombin time (TT), activation of blood coagulation time (APTT) and prothrombin time (PT) of purified MEAP were determined. Results The purity of synthetic crude and purified MEAP was 65.5% and 95.5% respectively. Anticoagulant activity experiments showed that both APTT and TT of synthetic MEAP had significant delayed effect (P < 0.01). Conclusion MEAP by using solid phase peptide synthesis method has anticoagulant activity. |
