磺丁基醚-β-環(huán)糊精鈉,是一種新型藥物制劑輔料,屬于陰離子型高水溶性環(huán)糊精的一種磺酸基衍生物。它能很好地與藥物分子包合形成非共價復合物,提高了藥物的穩(wěn)定性、水溶性、安全性并且有效的提高了藥物分子的生物活性它的腎毒性小,能緩和藥物溶血性,控制藥物釋放速率。
以β-環(huán)糊精和1,4-磺丁內(nèi)酯為原料,通過向堿性水溶液中引入適量有機溶劑,增加了1,4-磺丁內(nèi)酯的溶解度,提高了磺丁基醚-β-環(huán)糊精的合成收率;所得產(chǎn)品溶液經(jīng)過超聲透析,活性炭脫色,冷凍干燥等操作得到磺丁基醚-β-環(huán)糊精粉末產(chǎn)品。
SBE-β-CD is a chemically modified β-CD that is a cyclic hydrophilic oligosaccharide which is negatively charged in aqueous media. β-CD functioned is a solubilizer only at low concentrations, whereas SBE7-β-CD exhibits strong solubilizing effects over a wide concentration range.
20% SBE-β-CD in saline: Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs). 1. Dissolve 0.9 g of NaCl in 100 mL distilled water to make a clear 0.9% saline solution. 2. Measure 2 g of dry SBE-β-CD. 3. Dissolve 2 g of SBE-β-CD in 0.9% saline to make 10 mL with a 20% (w/v) concentration. These may require ultrasonic (20-40 kHz, 30 seconds, repeat 3 times) or heating (37°C for about 30 minutes). If precipitation is observed, the precipitates can be dissolved by heating to 37°C and vortexing before use.
