本发明进一步公开了所述抗肿瘤环肽的制备方法,本发明方法采用固相合成法来制备所述抗肿瘤环肽。所述固相合成法可通过以下措施达到:
采取Fmoc方案,选取CTC高分子树脂,将所述抗肿瘤环肽的C端即羧基端采用Fmoc-Gly-OH以共价键形式连接到CTC树脂上,洗涤,然后脱掉Fmoc保护基团,以结合在CTC树脂上的Gly的氨基作为合成起点,然后按照所述抗肿瘤环肽从C端即羧基端到N端即氨基端的氨基酸序列CGHIKFGYVRCG的顺序,分别依次进行缩合反应形成肽键,脱Fmoc保护,缩合反应形成肽键,不断重复循环上述步骤,直到序列全部偶联完全,脱Fmoc保护;之后切割CTC树脂得多肽粗品,利用反相高效液相色谱法进一步纯化,经过处理使两个Cys形成二硫键成环;再用反相高效液相色谱法纯化得到纯度高达95.62%的目标环肽。
本发明提供了所述抗肿瘤环肽在制备抗肿瘤药物中的应用。所述肿瘤包括肝癌和宫颈癌。所述抗肿瘤环肽在5-500μM浓度范围内对肝癌细胞HepG-2和宫颈癌细胞Hela的增殖抑制率分别为2.4%-98.6%和1.7%-96.7%。其IC50值分别为59.30μM,75.87μM。

具体实施方式
本发明的具体实施方式结合以下实施例来说明,但本发明并不限于以下实施例。
实施例1抗肿瘤环肽的固相合成
在本发明所述的抗肿瘤环肽的固相合成过程中,采用Fmoc方案,选取CTC树脂,经过处理使树脂暴露出活性位点,将Fmoc-Gly-OH以共价键形式连接到CTC树脂上,用DMF洗涤树脂。再加入体积浓度为25%的哌啶/DMF溶液脱掉Fmoc保护基团。利用标准的固相合成过程(SPPS),加入HBTU、N-甲基吗啉和Fmoc-Cys(Trt)-OH,使Fmoc-Cys(Trt)-OH与已经连接在CTC树脂上的Gly发生脱水缩合反应通过肽键连接在一起,茚三酮检测反应是否完全。再加入体积浓度为25%哌啶/DMF溶液脱掉Fmoc保护基团。不断重复上面的过程,按照氨基酸序列CGHIKFGYVRCG的顺序依次连接上去,直到序列全部偶联完全,脱Fmoc保护基团。树脂用甲醇洗涤待切割。将树脂转移到切割管中,加入现有技术中包括TFA、H2O、苯酚、EDT、苯甲硫醚等一种溶液或多种溶液的混合溶液,乙醚沉淀,切割完树脂得多肽粗品。利用反相高效液相色谱法进一步纯化,然后溶于纯水中,将1%的I2/MeOH溶液(即每1gI2溶解对应于100ml的MeOH)缓慢滴加到溶液中,使两个Cys形成二硫键成环。用二氯甲烷萃取水溶液,用反相高效液相色谱法纯化得到纯度为95.62%的抗肿瘤环肽。
实施例2采用CCK-8法测定环肽对肝癌细胞HepG-2增殖的抑制作用
将肝癌细胞HepG-2细胞悬液(1.5×104个/mL)按照每孔200μL的体积加入96孔板内,于37℃恒温CO2培养箱培养。24h之后细胞贴壁生长,吸出旧的培养液,将抗肿瘤环肽配制成浓度为5-500μM的溶液,加入96孔板内,并设置阴性对照和空白对照,于37℃恒温CO2培养箱培养。48h后,吸出药液,加入CCK-8溶液,继续于37℃恒温CO2培养箱培养。2h后,在酶标仪上测其在450nm波长处的吸光度值。由表1可知,抗肿瘤环肽在5-500μM浓度的作用下对肝癌细胞HepG-2的增殖抑制率为2.4%-98.6%,其IC50值为59.30μM。
