A gramicidin S analog ([Orn1,1']GS.4HCl) containing L-ornithine in place of L-valine at the 1,1' positions was synthesized by the conventional solution method in order to examine whether this analog had antibacterial activity toward Gram-negative bacteria. In the synthesis of [Orn1,1']GS.4HCl, two intermediate analogs ([Orn1,1', Orn(For)2,2']GS.2HCl and [Orn(Z)1,1']GS.2HCl) were obtained. [Orn1,1']GS
通过常规溶液法合成了在1,1'位置上含有L-鸟氨酸代替L-缬氨酸的短杆菌肽S类似物([Orn1,1'] GS.4HCl),以检查该类似物是否具有抗菌活性。革兰氏阴性细菌。在[Orn1,1'] GS.4HCl的合成中,有两个中间体类似物([Orn1,1',Orn(For)2,2'] GS.2HCl和[Orn(Z)1,1'] GS.2HCl )。[Orn1,1'] GS.4HCl和[Orn1,1',Orn(For)2,2'] GS.2HCl对革兰氏阴性或革兰氏阳性细菌均无活性,而[Orn(Z)1, 1'] GS.2HCl仅对革兰氏阳性细菌表现出明显的活性。
