Abstract:

Erlotinib (ELT) as a small molecule with poor solubility, poor bioavailability, and instability in gastrointestinal environment, has been considered as a therapeutic agent for Non-Small-Cell Lung Cancer (NSCLC) therapy through oral administration. In the present study, ELT-liposome and ELT-NLCs were successfully prepared and characterized by assessment of the particle size, zeta potential (ZP), polydispersity index (PDI), encapsulation efficiency (EE) and drug loading (DL). DAPI staining and Flow cytometry techniques were employed to probe anticancer activities of the optimal formulations. The obtained results indicated that the average size of optimized ELT-NLCs was 109±2 nm, while the optimal formulation of ELT-liposome was 130±4 nm. In addition, the values of EE, DL and cellular uptake were higher in ELT-NLCs than ELT-liposome. Moreover, the stability of ELT-NLCs and ELT-liposome were not significantly changed (P > 0.05) within storage time. The results of anti-cancer assessment showed that ELT-NLCs caused more cell viability reduction than ELT-liposome and free ELT. According to the Flow cytometry and DAPI staining results, the exposed A549 cells with ELT-NLCs had more rate of apoptosis than ELT-liposome. The obtained data from this study clearly showed that ELT-NLCs had better anti-cancer activity than ELT-liposome, which may be is related to the effective nano particle size, PDI, EE, and DL of ELT-NLCs.

A comparative evaluation of coenzyme Q10-loaded liposomes and solid lipid nanoparticles as dermal antioxidant carriers

BACKGROUND The effective delivery of coenzyme Q10 (Q10) to the skin has several benefits in therapy for different skin pathologies. However, the delivery of Q10 to deeper layers of skin is challenging due to low aqueous solubility of Q10. Liposomes and solid lipid nanoparticles (SLN) have many advantages to accomplish the requirements in topical drug delivery. This study aims to evaluate the in...
