体外研究 | Magainin 1通过透化细胞膜杀死细菌而不显示对哺乳动物细胞的显着毒性。肽的主要目标被认为是膜的脂质基质[1]。 Magainin 1和2具有相似的氨基酸序列。 Magainin 2具有比magainin 1更高的抗菌活性[2]。 Magainin 1通过静电相互作用与酸性脂质相互作用,然后通过疏水相互作用形成两亲性螺旋,从而引发渗漏。 Magainin 1特异性地诱导钙黄绿素从带负电荷的囊泡中泄漏。根据Langmuir等温线,该肽与牛脑磷脂酰丝氨酸超声囊泡结合,结合常数为3.8×105 M-1,每个脂质分子的结合位点数为0.10 [3]。 Magainin 2显示抗大量革兰氏阴性和革兰氏阳性细菌的抗生素活性。在magainin 1的测定中可以看到类似的活性谱[4]。 |
