一般描述
4-羟基二苯甲酮可吸收紫外光辐射转换为低能辐射，可用作有效的光稳定剂。它的分子结构由1个羰基连接2个芳环组成，强烈的π-π堆积作用可提高其在聚合物基质中的稳定性和作用。4-羟基二苯甲酮掺入聚合物基质后，可增加材料的寿命和性能，适于涂料和塑料等户外应用。
应用
4-羟基二苯甲酮可用于：
- 作为光引发剂合成荧光三嵌段共聚物胶束，用于肿瘤药物靶向释放和细胞内生物成像。它可改善药物控释、提高疗效同时最大限度降低副作用。
- 作为光酸催化剂，用于内酯类开环聚合制备生物可降解聚酯类。
- 作为前体合成功能型共聚物，以制造纳米结构的透明金属电极用于柔性光电器件。

Cardiac enzymes such as cytochrome P450 2J2 (CYP2J2) metabolize arachidonic acid (AA) to cardioprotective epoxyeicosatrienoic acids (EETs), which in turn are metabolized by soluble epoxide hydrolase (sEH) to dihydroxyeicosatrienoic acids (DHETs). As EETs and less potent DHETs exhibit cardioprotective and
