姜黃素衍生物C210的納米劑型制備及其抗腫瘤活性研究姜黃素衍生物C210的納米劑型制備及其抗腫瘤活性研究

摘要：姜黃素是一種天然植物提取物，其具有廣泛的生物活性和治療應(yīng)用。為了提高其溶解度和生物利用度，我們開發(fā)了一種納米劑型C210。本研究旨在探討C210對人體腫瘤細(xì)胞株的抗腫瘤活性以及納米劑型制備的制備條件。利用脂質(zhì)體技術(shù)，制備出C210納米粒子，通過動態(tài)光散射儀和透射電子顯微鏡確定其粒徑和形態(tài)。紫外-可見光譜和熒光光譜進(jìn)一步證明了C210納米粒子的形成。體外細(xì)胞實驗結(jié)果表明，與純C210相比，C210納米粒子具有更高的細(xì)胞毒性和抑制腫瘤細(xì)胞增殖的活性。通過癌癥小鼠模型，我們進(jìn)一步證實了C210納米粒子的抗腫瘤活性，并發(fā)現(xiàn)其對正常組織的毒副作用明顯降低?？傊?，C210納米劑型具有廣泛的生物應(yīng)用前景，但其制備條件需要進(jìn)一步優(yōu)化。
