all galaxamide analogues exhibited growth inhibition in A549, A549/DPP, SMMC-7721 and HepG2 cell lines. Compounds 6, 18, and 22 exhibited interesting activities towards all cell line tested, while Compounds 1, 4, 15, and 22 showed strong activity towards SMMC-7221 cell line in the range of 1-2 μg/mL IC50. Flow cytometry experiment revealed that galaxamide analogues namely Compounds 6, 18, and 22 induced
在此,我们报道了具有N-甲基化环五肽的新型26 galaxamide类似物的设计和合成,以及它们对人肿瘤细胞系(例如A549,A549 / DPP,HepG2和SMMC-使用MTT分析的7721。我们还研究了galaxamide及其代表类似物对SMMC-7721细胞体外生长,细胞周期阶段和诱导凋亡的影响。考虑到构象空间和构成该化合物模板的N-Me氨基酸(aa)的重要性,我们设计了在N-Me-aa位置修饰,aa构型从l变为d aa的类似物,并用一个Leu-aa取代为类似物。对应于母体结构的d / l Phe-aa残基。对于含N-Me aa的线性五肽残基,采用有效的固相平行合成方法,然后进行溶液相大环化,得到目标环五肽化合物。在本研究中,所有的galaxamide类似物在A549,A549 / DPP,SMMC-7721和HepG2细胞系中均表现出生长抑制作用。化合物6、18和22对所有测试的
