Abstract

This study aimed to formulate and characterize the folate receptor-targeted PEGylated liposome encapsulating bioactive compounds from Kappaphycus alvarezii to enhance the anticancer activity. Twenty valued bioactive compounds (3-hydroxy benzoicacid, gallicacid, chlorogenicacid, cinnamicacid, artemiseole, hydrazine carbothioamide, etc.,) are confirmed from methanol extract of K. alvarezii using analytical techniques like HPLC and GC-MS. The delivery of bioactive compounds of K. alvarezii via naturally overexpressed folate receptor (FR) to FR-positive breast cancer cells was studied. FR targeted PEGylated liposome was constructed by modified thin-film hydration technique using FA-PEG-DSPE/cholesterol/DSPC (5:40:55) and bioactive compounds of K. alvarezii was encapsulated. Their morphology, size, shape, physiological stability and drug release kinetics were studied. The study reports of K. alvarezii extract-encapsulated PEGylated liposome showed spherical shaped particles with amorphous in nature. The mean diameter of K. alvarezii extract-encapsulated PEGylated and FA-conjugated PEGylated liposomes was found to be 110 ± 6 nm and 140 ± 5 nm, respectively. Based on the stability studies, it could be confirmed that FA-conjugated PEGy...Continue Reading
