freeze-dried black raspberry bioadhesive gel
A bioadhesive gel containing 10% freeze-dried black raspberries (FBR) with potential chemopreventive and antioxidant activities. The four main constituent black raspberry anthocyanins that contribute significantly to the chemopreventive effects are cyanidin 3-glucoside (C3GLU), cyanidin 3-rutinoside (C3RUT), cyanidin 3-sambubioside (C3SAM) and cyanidin 3-(2(G)-xylosyl) rutinoside (C3XRUT). Upon mucosal application, the anthocyanins from the gel penetrate the oral mucosa and are able to modulate expression of certain proapoptotic and terminal differentiation genes, and reduce the expression of epithelial cyclooxygenase-2 (COX-2) protein. In addition, this gel may also reduce vascular densities in the superficial connective tissues. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
