Linalool is a monoterpene alc. which occurs naturally in several aromatic plants. The aims of this study are to load Linalool on gold nanoparticles, conjugate the complex with CALNN peptide, and investigate them for in-vitro anticancer activities against breast cancer (MCF-7) cell line. Linalool was obtained with 98% purity while gold nanoparticles and CALNN peptide were chem. synthesized. The formation of LIN-GNPs and LIN-GNPs-CALNN was observed through a color change. These compounds were confirmed and characterized using SEM, DLS, AFM, UV-VIS spectrophotometer, XRD, and FTIR. The free radical scavenging potential of each compound was confirmed based on its stable antioxidant effects using different parameters. Blood compatibility on red blood cells was confirmed by hemolytic and in vitro cytotoxicity assays. The in-vitro anticancer activity of each compound towardMCF-7 cell line was investigated using various parameters. From the results, Linalool, GNPs, LIN-GNPs, and LIN-GNPs-CALNN were found to exert cell growth arrest against MCF-7 cell line. The anti-proliferative effect of these compounds was due to cell death and induction of apoptosis confirmed using acridine orange-Ethidium bromide dual staining, DAPI staining, and electrophoresis anal. of DNA fragmentation. High fluorescent signals specific for the cellular uptake of LIN-GNPs and LIN-GNPs-CALNN into the cytoplasm of the cell line were confirmed. To study the toxicity of LIN-GNPs-CALNN in animal models, the hematol., histopathol., and body weight changes were estimated after 4 wk of i.p. injection of the compounds into the animal models. Our results demonstrate that Linalool, GNPs, Linalool-GNPs, and Linalool-GNPs-CALNN peptide had no side effects and could be clin. used for future therapeutic purposes.
