Molecular Modeling In Silicoand Development of Coenzyme Q10 Nanostructured Lipid Carriers (NLC) In Vitroand In Vivoon Cosmetics Delivery System

 

The development of coenzyme Q10 nanostructured lipid carriers (NLCs) was carried out by molecular modeling in silico, followed by in vitroand in vivostudies. Coenzyme Q10 is a lipophilic antioxidant, so the penetration into the skin is low. The limitation is overcome by NLCs. The molecular modeling in silicowas conducted by AutoDock Vina. The optimized coenzyme Q10 NLCs were developed using tristearin (F1), stearic acid (F2), myristic acid (F3), and stearyl alcohol (F4) as solid lipids, as well as isopropyl palmitate as liquid lipid. They were evaluated on physicochemical characteristics and the rats' skin penetration in vivo. Furthermore, the physical and chemical (pH) stabilities were evaluated by the accelerated stability method at a temperature of 40°C ± 2°C with a relative humidity of 75% ± 5% for 3 months. The research could be concluded that the coenzyme Q10 NLC (F1), (F2), (F3), and (F4) had proper physicochemical characteristics and skin penetration as cosmetics delivery systems. The coenzyme Q10 NLC (F2) and (F3) had optimal physical and chemical (pH) stabilities. There were linear correlations between the ΔGbind coenzyme Q10-lipids in silicowith the entrapment efficiency and drug loading of the coenzyme Q10 NLCs. There were no linear correlations between the ΔGbind coenzyme Q10-lipids in silicowith the release rate constant in vitroand the skin penetration in rats of the coenzyme Q10 NLCs in vivo.
