今天小编给大家分享了紫杉醇联合2-甲氧基雌二醇的白蛋白纳米粒/荜茇酰胺白蛋白纳米粒的研究制备,和小编一起来看!
紫杉醇联合2甲氧基雌二醇的白蛋白纳米粒的制备方法:
可有效解决紫杉醇细胞株的敏感性低,生物利用度低,不良反应强,采用去溶剂化法化学交联法制备紫杉醇联合2甲氧基雌二醇的白蛋白纳米粒,本发明方法简单,易生产制备,制备出的纳米粒稳定性好,靶向性强,能够保护其免受环境影响,起效快,不良反应小,次数少,具有缓释作用生物利用度高,稳定性好,制备简单,有利于患者使用,提高靶向性及其效果,增加紫杉醇细胞的敏感性,具有非常重要的临床意义。
荜茇酰胺白蛋白纳米粒制备方法:
将荜茇酰胺原料溶于适量有机溶剂中,作为有机相.将牛血清白蛋白溶解在纯水中,作为水相.在高速剪切作用下将有机相缓慢滴加到水相中,剪切分散得到初乳.将所得初乳转移到高压微射流纳米分散仪中,适当压力下进行均质.均质完成后通过旋转蒸发除去有机溶剂,得到荜茇酰胺白蛋白纳米粒,冻干,得到荜茇酰胺白蛋白纳米粒冻干粉.本发明提供的荜茇酰胺白蛋白纳米粒可以改善荜茇酰胺的水溶性,提高生物利用度,且其制备工艺简单,避免了戊二醛的使用,安全性好.
