Abstract:
The present invention relates to a method for manufacturing a DNA hydrogel which has adhesive characteristics using a compound which includes two or more pyrogallol functional groups as a cross-linking agent. The present invention can be used for medicine for a gene treatment and an adhesive carrier for a local injection since the present invention is able to: synthesize the DNA hydrogel in a short time by combining a compound which includes two or more pyrogallol functional groups and a DNA solution of high concentration; control the physical properties of the DNA hydrogel according to the concentration of the compound which includes two or more pyrogallol functional groups; and emit DNA according to the decomposition degree of the compound which includes two or more pyrogallol functional groups which are a cross-linking agent when being exposed to a solution of pH7.4.
Abstract:
PURPOSE: A hyaluronic acid catechol conjugate and uses thereof are provided to easily give adhesiveness to biocompatible hyaluronic acid as well as to coat various solid surfaces with the biocompatible hyaluronic acid. CONSTITUTION: A hyaluronic acid catechol conjugate is formed by the bonding between carboxyl group of hyaluronic acid and amine group of dopamine with amide bonds. A manufacturing method of a hyaluronic acid catechol conjugate includes the following steps: a step of putting EDC(1-Ethyl-3-[3-dimethyl aminopropyl]carbodiimide Hydrochloride) and NHS(N-hydroxysuccinimide) into a mixture solution of hyaluronic acid and dopamine each with the same equivalent as a dopamine equivalent; a step of allowing the synthesized material to react at pH 2-7 for 2-18 hours; and a step of refining the synthesized material at pH 2-7.
