Bombesin conjugated solid lipid nanoparticles for improved delivery of epigallocatechin gallate for breast cancer treatment.

Epigallocatechin-gallate (EGCG) is a potent anti-cancer therapeutic which effectively controls the growth of cancerous cells through a variety of different pathways. However, its molecular structure is susceptible to modifications due to cellular enzymes affecting its stability, bioavailability and hence, overall efficiency. In this study, we have initially encapsulated EGCG in the matrix of solid lipid nanoparticles to provide a stable drug carrier.

Encapsulation of biophenolic phytochemical EGCG within lipid nanoparticles enhances its stability and cytotoxicity against cancer.

Epigallocatechin gallate (EGCG), a green tea polyphenolic catechin, has been known to possess a variety of beneficial biological activities. The in-vitro anti-cancer activity of EGCG is well documented. However, the use of EGCG in modern therapeutics is limited due to its poor bioavailability and limited stability at physiological pH.
