为了研究H 2 O 2的生理和病理作用,迫切需要选择性和灵敏的过氧化氢(H 2 O 2)分子探针,它们在氧化应激和氧化还原信号传导中起着不同的作用。缺乏用于体内成像的可靠工具已经阻碍了H 2 O 2介导的治疗剂的发展。通过将特定的串联Payne / Dakin反应与化学发光支架相结合,H 2 O 2 -CL-510被开发为用于检测H 2 O 2的高选择性和灵敏探针无论是体内还是体外。H 2 O 2无需任何激光激发即可直接触发化学发光的430倍快速增强。成功检测到三氧化二砷诱导的白血病的氧化损伤。特别是,使用H 2 O 2 -CL-510在大鼠大脑中观察了脑缺血再灌注损伤诱导的H 2 O 2通量,为实时监测活体动物中H 2 O 2的动力学提供了新的化学工具。

aldehyde lithiation. Nevertheless, the existing methodologies for their formation typically employ harsh conditions limiting their usefulness. In this work, we present an efficient and mild methodology for the preparation of aminals from aromatic aldehydes, including furanic platforms. These mildconditions allowed ease of access to a plethora of aminals and as such we set out to explore previously unaccessible

and the process for producing thereof from the optically active 1-substituted phenyl-2-nitro alcohol derivatives. From these nitro alcohols, pharmaceuticals such as (R)-albutamin and (R)-sarmeterol useful as a bronchodilator is obtained via optically active amino alcohols which are useful pharmaceutical intermediates.
