Problems solved by technology

3-Hydroxyflavone derivatives have a large conjugated structure, which directly causes their poor solubility in the state of small molecules, and usually need to add organic solvents to aid in dissolution
At present, in the light-responsive carbon monoxide donor molecules, due to the existence of the naphthalene ring structure, it needs to be dissolved in the presence of organic solvents. The toxicity of organic solvents makes it impossible to be directly used in vivo, which greatly limits the light-triggered Application of releasing carbon monoxide in medicine

Abstract

The present invention provides a carbon monoxide donor molecule with fluorescent properties and a preparation method and application thereof. The carbon monoxide donor molecule with the structure represented by the formula (I) provided by the present invention can realize a responsive protection element in the next step under illumination conditions The removal of carbon monoxide and the release of carbon monoxide, and the carbon monoxide donor molecule can be further prepared to obtain a stable polymer, which can be further prepared into a water-stable assembly material by self-assembly. Compared with the existing carbon monoxide For releasing molecules, the carbon monoxide donor provided by the present invention has good controllable release and good biocompatibility.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a carbon monoxide donor molecule with fluorescent properties and its preparation method and application. Background technique [0002] Carbon monoxide is well known as a toxic gas molecule. In recent years, studies have found that carbon monoxide is similar to nitrogen monoxide and hydrogen sulfide, and can also be used as a gas transmitter. In the human body, carbon monoxide is produced by the cleavage of heme oxidase, which has important applications in protecting cells, regulating physiological processes, anti-inflammation and anti-cancer. However, since the binding speed of carbon monoxide and hemoglobin far exceeds that of oxygen and hemoglobin, the uncontrollable direct inhalation of carbon monoxide makes this method impractical, [0003] At present, the donor materials used to prepare and release carbon monoxide mainly include metal coordination compounds (CORM-2 / CORM-3) ...
