Nanoencapsulation of caffeic acid phenethyl ester in sucrose fatty acid esters to improve activities against cancer cells

Caffeic acid phenethyl ester (CAPE) is a natural compound with anticancer activities but has low water solubility. In this work, sucrose fatty acid ester (SFAE) was used to nanoencapsulate CAPE in aqueous propylene glycol (PG) with a temperature-cycle method by heating at 90 °C for 20 min and cooling to 21 °C, followed by additional heating at 90 °C for 5 min and cooling to 21 °C. A higher amount of PG facilitated encapsulation with up to...
