Background:
Chitosan-coated liposome containing both coenzyme Q10 and alpha-lipoic acid (CCAL) was a novel multifunctional nano delivery system exhibited long-term stability at room temperature and high encapsulation efficiency. Which containing two kinds of antioxidants (coenzyme Q10 and alpha-lipoic acid) and two antibacterial agents (chitosan and alpha-lipoic acid). However, the further biocompatibility, such as cytotoxicity and antioxidant activity, and antimicrobial activity of CCAL, has not been systematically evaluated.
Objectives:
This study aims to evaluate the cytotoxicity, antioxidant activity and antimicrobial activity of CCAL.
Methods:
This article evaluated the in vitro cytotoxicity and antioxidant activity of CCAL by CCK8 assay, and antimicrobial activity on Staphylococcus aureus and Escherichia coli was investigated.
Results:
For antioxidant activity study, CCAL displayed significant antioxidant effect when compared with control group (P<.01). Finally, CCAL also exhibited antimicrobial activity, and CCAL showed stronger bactericidal effect with Gram-positive bacteria than Gram-negative bacteria.
Conclusions:
CCAL could be a potential antioxidant delivery system for cosmetics or pharmaceuticals without cytotoxicity and artificial preservatives free.
