1,2-Dimyristoyl-rac-glycero-3-phosphocholine, a zwitterionic phospholipid, was chosen as a simple but suitable membrane model of the human cell membrane for mimicking the neutral charge of the surface membrane of eukaryotic plasma membranes[1]. The effect of antibiotics such as Rifabutin on human cell membrane models was assessed using multilamellar vesicles (MLVs) composed of 1,2-Dimyristoyl-rac-glycero-3-phosphocholine[1-2]. 1,2-Dimyristoyl-rac-glycero-3-phosphocholine can serve as a model lipid membrane to study the effects of DMSO and drugs on eukaryotic cell membranes[3-5]. 1,2-Dimyristoyl-rac-glycero-3-phosphocholine can also be used to prepare polydiacetylene (PDA)[6]. 1,2-Dimyristoyl-rac-glycero-3-phosphocholine experiences an increase in headgroup area, enhanced membrane disorder, and increased fluidity due to DMSO, but the bilayer does not disintegrate[4].

1,2-Dimyristoyl-rac-glycero-3-phosphocholine是一种两性离子磷脂,被选作简单且合适的人类细胞膜模型,用于模拟真核细胞质膜表面的电中性[1]。通过使用由1,2-Dimyristoyl-rac-glycero-3-phosphocholine组成的多层脂质体(MLVs),评估了如利福布汀等抗生素对人类细胞膜模型的影响[1-2]。1,2-Dimyristoyl-rac-glycero-3-phosphocholine可以作为模型脂质膜,用于研究DMSO和药物对真核细胞膜的影响[3-5]。此外,1,2-Dimyristoyl-rac-glycero-3-phosphocholine还可用于制备聚二乙炔(PDA)[6]。由于DMSO的作用,1,2-Dimyristoyl-rac-glycero-3-phosphocholine的头基面积增大,膜的无序性增强,流动性增加,但双层膜并未解体[4]。
