Abstract: It relates to a mucus adhesion drug delivery technology. The technology involves the preparation of materials consisting of mucus adhesive excipient polymer chemically bonded with drug molecules and delivery of the materials with fast disintegration tablet with enteric coating to intestine. The bonding between the excipient polymer and the drug molecules is either ionic bonds, covalent bonds, or metal coordination bonds. The test of the mucus adhesion drug delivery technology was carried out using a dog model. The test data indicated successful retaining of drug molecules on the intestine mucus resulting in not only dramatic extension of drug release time, but also great improvement in the bioavailability of the API.

Abstract: A DOPA-Gelatin is disclosed in which the monophenolic group of tyrosine, a prominent amino acid in porcine gelatin, is converted into a catechol group using an enzyme-based DOPA modification technique. The resulting DOPA-Gelatin has been discovered to exhibit good mechanical strength and adhesion. Moreover, in vitro studies show that DOPA-Gelatin has no cytotoxicity with HDF and HaCaT cells, two cells typically involved in the skin wound healing process. Further RT-PCR and angiogenesis investigation showed that DOPA-Gelatin can promote the expression of wound-related genes and facilitate neovascularization. In a full-thickness dorsal defect model in mice, DOPA-Gelatin treated groups decreased the wound closure time and enhanced hair follicle growth. These results demonstrate that the DOPA-Gelatin hydrogel compositions disclosed herein are an effective functional biomaterial that can potentiate the wound healing process.
