Chiral recognition was observed in the interactions of gold nanoparticles grafted with (±)-, (M)-, and (P)-helicenethiol. Although the nanoparticles contain equal enantiomeric excess, a 1 : 1 mixture of (M)- and (P)-nanoparticles aggregated more rapidly in solution than (±)-nanoparticles.
Lysine-reactive activity-based probes based on arylfluorosulfates (ArOSO2F) are reported, enabling successful profiling of >300 endogenous kinases and providing a global landscape of ligandable catalytic lysines of the human kinome. Introduction of these aminophiles into a noncovalent Aurora A kinase inhibitor led to novel lysine-reactive inhibitors that exhibited excellent in vitro potency and cellular
据报道,基于芳基氟硫酸盐 (ArOSO 2 F) 的赖氨酸反应活性探针能够成功分析超过 300 种内源激酶,并提供人类激酶组可配体催化赖氨酸的全球概况。将这些亲氨基物质引入非共价 Aurora A 激酶抑制剂中产生了新型赖氨酸反应性抑制剂,该抑制剂表现出优异的体外效力和细胞活性,并具有较长的停留时间。
