一般說明

聚乙二醇12羟基硬脂酸酯是一种不依赖pH值的非离子表面活性剂,是一种有效的增溶剂和乳化剂。它可溶于水介质和极性有机溶剂,但不溶于非极性溶剂。其结构为12-羟基硬脂酸(亲脂部分)和聚乙二醇(亲水部分)。

應用

  • 聚乙二醇12羟基硬脂酸酯已用于:
  • 溶解于地塞米松(DEX),以将其腹腔注射到小鼠体内,测试其握力,进而测量肌肉力量
  • 以罗氟司特制剂治疗家兔和豚鼠,以研究臭氧诱导的剧烈咳嗽(hypertussive)反应的机制和药理敏感性
  • 溶解非奈利酮,以进行口服应用的体内研究

生化/生理作用

聚乙二醇12羟基硬脂酸酯(12-Hydroxy-octadecanoic acid polymer with α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl))主要用作肠外和口服制剂的增溶剂。它是化合物的体外筛选和体内疗效研究的首选。聚乙二醇12羟基硬脂酸酯还因其增溶特性和安全性,可用于眼科、大分子、栓剂和蛋白质制剂中。通常可形成10-15纳米的胶束。聚乙二醇12羟基硬脂酸酯可用于开发微乳液IV制剂(micro-emulsion IV formulations)。

其他說明

聚乙二醇12羟基硬脂酸酯是一种非离子型去污剂,由15摩尔环氧乙烷与1摩尔12-羟基硬脂酸反应生成。
