Abstract
An androstane (17β-hydroxy-17α-picolyl-androst-5-en-3β-yl-acetate (derivative A)) cancer inhibitor was successfully captured in a carrier made of nano-sized hydroxyapatite (HAp) coated with chitosan-PLGA polymer blends (Ch-PLGA). In our previous studies, we demonstrated that it was convenient to use spherical HAp/Ch-PLGA carriers as vehicles to target the lungs following intravenous administration. In this study, we used emulsification and subsequent freeze-drying to load the spherical HAp/Ch-PLGA carriers with varying contents of the derivative A, in order to examine the selective toxicity towards cancerous/healthy lung cells. The XRD and FT-IR techniques confirmed the drug loading process, and the content of the poorly water soluble derivative A was estimated directly via the DSC technique. The particles were spherical in shape with the d50 distribution varying between 167 and 231 nm, whereas the content of the derivative A ranged from 6.5 to 19.3 wt%. Cell-selective cytotoxicity was... examined simultaneously on two cell lines: human lung carcinoma (A549 ATCC CCL 185) and human lung fibroblasts (MRC-5 ATCC CCL 171). All particles exhibited nearly three times larger cytotoxicity towards cancer cells (A549) than towards healthy cells (MRC5), where the particles with the derivative A content of 6.5 wt% allowed for the viability of healthy cells >80%. Ninety-six hours after the treatment of cells with particles with different contents of derivative A (after incubation and recovery), recovery was faster in damaged healthy cells than in cancerous cells. © 2018 Elsevier B.V.
