Preparation and Preliminary Evaluation of #Epigallocatechin Gallate Microcapsules on Gallbladder #CancerCell Growth by F Acevedo in BJSTR

Abstract

Background: Gallbladder cancer is a highly #ethal pathology, mainly due to late #diagnosis and poor therapeutic alternatives. Epigallocatechin gallate (EGCG) has been reported as a cancer #chemoprophylaxis, but its low stability and bioavailability limit its utility. The purpose of this study was to define the optimal process conditions by nano spray drying for EGCG microencapsulation using gum arabic and #maltodextrin as a wall material and to test its chemopreventive action efficiency on #gallbladdercancercell lines (GB-d1).
Methods: For microcapsule production using a Büchi nanospray dryer, an experimental Taguchi design was applied using a L4(23) matrix. The effects of #cytotoxicity and reactive oxygen species (ROS) production on GB-d1 cells in the presence of #microencapsulated EGCG were assessed.
