General description

泊洛沙姆407是一种水溶性非离子表面活性剂,具有低毒性和良好的增溶能力。这种三嵌段共聚物由疏水的聚氧丙烯(POP)残基和两侧亲水的聚氧乙烯(POE)单元组成。

Application

泊洛沙姆407已被用于:
  • 作为脂蛋白脂肪酶活性的抑制剂,以评估小鼠肝脏极低密度脂蛋白 (VLDL)-甘油三酯(TG)的分泌
  • 用于小鼠VLDL分泌测定
  • 溶解在磷酸盐缓冲盐水(PBS)中,通过腹膜内注射进小鼠以产生肝甘油三酯

Biochem/physiol Actions

泊洛沙姆407 (P407)在特定的聚合物浓度和温度以上表现出可逆的胶凝特性。泊洛沙姆407-基无菌注射制剂是药物传递的优秀候选物。P407热敏水凝胶广泛用作粘膜药物传递系统,因为它们不会刺激粘膜。P407被美国食品和药物管理局(FDA)称为“非活性成分”,适用于多种药物产品,如口服溶液、悬浮液和吸入制剂。
