Preliminary results of the effect of hydrophobicity and halogenation on the cytotoxicity of the anticancer peptaibol culicinin D are reported. Building on previous work, the synthetically challenging (2S,4S,6R)-2-amino-6-hydroxy-4-methyl-8-oxodecanoic acid and (2S,4R)-2-amino-4-methyldecanoic acid building blocks were replaced with derivatives of l-phenylalanine and 2-aminodecanoic acid, respectively
报道了疏水性和卤化对抗癌 peptaibol culicinin D 的细胞毒性影响的初步结果。在先前工作的基础上,合成具有挑战性的 (2 S ,4 S ,6 R )-2-amino-6-hydroxy-4-methyl-8-oxodecanoic acid 和 (2 S ,4 R )-2-amino-4-甲基癸酸结构单元被下列衍生物取代升-苯丙氨酸和 2-氨基癸酸,分别。(2 S ,4 S ,6 R )-2-amino-6-hydroxy-4-methyl-8-oxodecanoic acid取代升-4,4'-联苯丙氨酸产生的类似物的效力是天然产物的 10 倍,并且是最疏水的类似物,根据抗增殖 IC 50测定和 logD 计算判断;这些结果表明,culicinin D 的效力可能受其疏水性的控制。然而,将卤化部分引入肽序列产生类似有效的类似物,尽管不一定是疏水的。因此,调节 culicinin
