Provided is a method of inhibiting heterodimerization of HIF-2α to HIF1β (ARNT) comprising binding certain small molecules to the HIF-2α PAS-B domain cavity but not to HIF1α and inhibiting HIF-2α heterodimerization to HIF1β (ARNT) but not inhibiting HIF1α heterodimerization to HIF1β (ARNT). Those certain small molecules are also referenced synonymously as HIF2-HDI and HIF2α heterodimerization inhibitors and also simply as certain small molecules.
The biomimetic design of a transition metal complex based on the iron(IV)-oxoporphyrin π-cation radical species in cytochrome P450 enzymes has been studied extensively. Herein, we translate the functions of this iron(IV)-oxoporphyrin π-cation radical species to an α-ketoacyl phosphonium species comprised of non-metal atoms and utilize it as a light-activated oxygenation auxiliary for ortho-selective
基于细胞色素 P450 酶中铁(IV)-氧代卟啉 π-阳离子自由基物种的过渡金属配合物的仿生设计已得到广泛研究。在此,我们将这种铁( IV )-氧代卟啉π-阳离子自由基物种的功能转化为由非金属原子组成的α-酮酰基鏻物种,并将其用作苯胺邻位选择性氧化的光激活氧化辅助剂。可见光照射将 α-酮酰基鏻物质转化为激发态,充当瞬时产生的氧化剂。该过程的分子内性质确保了高区域选择性和化学选择性。辅助装置可轻松拆卸。还描述了一锅法。
