چکیده

نانو کیبوزوم‌ها مجموعه‌ای از ذرات لیپیدی هستند که می‌توان از آنها در فرایند تهیه نانو داروها استفاده کرد. در این پژوهش، ما به دنبال امکان‌سنجی تولید نانو کیبوزوم‌های کورکومین با پوشش روده‌ای و بررسی تأثیر درون پوشانی بر پروفایل رهایش و همچنین سمیت سلولی آن در شرایط آزمایشگاهی هستیم. در این مطالعه، فعالیت آنتی‌اکسیدانی کورکومین محصورشده و پروفایل رهایش آن در شرایط شبیه‌سازی شده گوارشی از طریق نانوحامل‌های پوشش‌داده شده ارزیابی شد. دو شکل آزاد و محصورشده در نانوحامل‌های پوشش‌داده شده روده برای تعیین اثر درون پوشانی بر پایداری آنتی‌اکسیدان‌ها مطالعه و اثر آنها بر زنده ماندن سلولی سلول‌های سرطانی روده بزرگ بررسی شد. تجزیه و تحلیل ویژگی‌ها، میانگین اندازه ذرات و اندازه پتانسیل زتا نانوکیبوزوم‌ها برابر با 9.17±53.54 نانومتر و 4.54±7.46- میلی‌ولت گزارش شده است. نتایج تحقیق نشان داد که نانوکیببوزوم‌های حامل کورکومین می‌توانند میزان IC50 سمیت سلولی را 1.55 برابر بیشتر از کورکومین آزاد پس از ۴۸ ساعت انکوباسیون بهبود بخشند.

چکیده [English]

Nanocubosomes are a collection of lipid particles that can be used in the preparation of nanoparticles. In this study, we seek to investigate the feasibility of producing curcumin nanocubosomes by intestinal lining and to investigate the effect of encapsulation on release profile and in vitro cell cytotoxicity. In this study, the antioxidant activity of encapsulated curcumin and its release profile in simulated gastrointestinal conditions through coated nanocarriers were evaluated. Two free and encapsulated forms in coated intestinal nanocarriers were studied to determine the effect of encapsulation on antioxidant stability. Then their effects on the cell viability of colon cancer cells were investigated. Character analysis reported that the mean particle size and zeta potential value of the nanocubosomes were 53.54± 9.17 nm and -7.46 ±4.54 mV. The results showed that nanocubosomes carrying curcumin could improve IC50 cytotoxicity by 1.55 times higher than free curcumin after 48 hours of incubation.
