一般說明

(2-羟丙基)-β-环糊精是一种羟烷基衍生物,经证可作为一种制剂载体,增强药物在水溶液中的溶解度,从而将药物成功递送至生物系统。通常用作α-、β-和γ-环糊精的替代物。

應用

(2-羟丙基)-β-环糊精可用于:
  • 作为薄层色谱法(TLC)测定药物制剂中分析物的分析标准品。
  • 在使用反相高效液相色谱(RP-HPLC)定量之前,研究宿主-客体的有机低分子量化合物相互作用。
  • 作为HPLC法有效分离β-咔啉的流动相添加剂。
  • 环糊精修饰的胶束电动色谱(CD-modified MEKC)测定盐酸舍曲林及与合成相关产物。

亲脂性药物的溶解度随着水溶液中的羟丙基-β-环糊精(HP-β-CD)浓度线性增加,这是因为HP-β-CD与药物形成了复合物。这种客体-宿主型复合物在药物与HP-β-CD的非极性空穴间形成,导致溶解度增强。HP-β-CD可用于制备与罗哌卡因(RVC)形成的包合物,以增加RVC溶解度,确保有效的药物递送。
亲脂性药物的溶解度随着水溶液中的羟丙基-β-环糊精(HBC)浓度线性增加,这是因为HBC与药物形成了复合物。这种客体-宿主型复合物在药物与HBC的非极性空穴间形成,导致溶解度增强。 可以将溶液冻干以产生易溶的粉末。 对家兔和小鼠无毒性。

Ropivacaine (RVC) is an enantiomerically pure local anesthetic (LA) largely used in surgical procedures, which presents physico-chemical and therapeutic properties similar to those of bupivacaine (BPV), but associated to less systemic toxicity. This study focuses on the development and pharmacological
