ABSTRACT
Capsaicin (CAP) is an active component in Capsicum annuum L. known to have anti inflammatory and anticancer activity. CAP is highly lipophilic and suffers low bioavailability. Therefore, developing delivery systems that enhance solubility and bioavailability can provide more promising therapeutic applications for CAP. In the current work, CAP was complexed with ß-cyclodextrin (ßCD) to form capsaicin-in-ß-cyclodextrin (CAP-in-ßCD) inclusion complexes. Then, the CAP-in-ßCD inclusion complexes were characterized and loaded into PEGylated liposomes using the thin-film hydration extrusion method. The size, charge, and polydispersity index (PDI) of the PEGylated liposomes were characterized. The levels of IL-8 production were quantified after treatment using array beads. The results of this work showed that the successful formation of inclusion complexes at 15 M ratio of CAP to ßCD respectively. PEGylated liposomes loaded with ßCD/CAP inclusion complexes (CAP-in-ßCD-in-liposomes) have a hydrodynamic diameter of (181 ± 36) nm, zeta potential of (-2.63 ± 4.00) mV, encapsulation efficiency (EE) of (38.65 ± 3.70)%, drug loading (DL) of (1.65 ± 0.16)%, and a stable release profile. Both free CAP and liposomal CAP showed a significant reduction in the IL-8 production by the MDA-MB-231 and A549 cancer cell lines after treatment. In conclusion, a liposomal-based drug delivery system for CAP was achieved.
