Development, characterization in vitro and in silico of coenzyme Q10 loaded myristic acid with different liquid lipids nanostructured lipid carriers

Abstract

Context: Nanostructured lipid carriers can enhance skin penetration of active substances. Coenzyme Q10 is a lipophilic antioxidant, that has poor skin penetration. This limitation is overcome by nanostructured lipid carriers. Aims: To developed coenzyme Q10 nanostructured lipid carriers using myristic acid with various liquid lipids as lipid matrix by in vitro studies and in silico approach for explaining the interaction of coenzyme Q10-lipid at the molecular level. Methods: The coenzyme Q10 nanostructured lipid carriers were prepared using myristic acid as solid lipid with oleic acid, isopropyl myristate, and isopropyl palmitate as liquid lipids using the high shear homogenization method. Then, they were evaluated in physicochemical characteristics by dynamic light scattering, differential scanning calorimetry, Fourier transforms infrared, scanning electron microscopy, spectrophotometry ultraviolet-visible, and pH meter. Furthermore, the in silico studies were conducted using AutoDock 4.2. Results: The coenzyme Q10 nanostructured lipid carriers using myristic acid-oleic acid, myristic acid-isopropyl myristate, and myristic acid-isopropyl palmitate as lipid matrix had the mean particle size, polydispersity index, entrapment efficiency, drug loading, and pH value were less than 300 nm, less than 0.3, more than 80%, about 10%, and about 5.0, respectively. Moreover, molecular docking of coenzyme Q10 and lipid showed hydrogen and hydrophobic bonds. These results supported differential scanning calorimetry and Fourier transforms infrared results. Conclusions: The coenzyme Q10 nanostructured lipid carriers were successfully prepared using myristic acid-oleic acid, myristic acid-isopropyl myristate, and myristic acid-isopropyl palmitate as lipid matrix as well as in silico study could be used for explaining of coenzyme Q10-lipid interaction.

“…It has also been emerging as an ideal drug delivery platform for the pharmaceutical market for oral or parenteral administration and delivery of nucleic acids such as miRNA for tumor genes. The advantages of these nanoparticles concerning the SLN and their superior biocompatibility, high biodegradability, and low immunogenicity make them useful for many clinical applications [151][152][153][154][155].…”
