Spin labels (7, 10, 13, 16, 22, 27) were synthesized from piperidinyloxyl (1), pyrrolidinyloxyl (2), and oxazolidinyloxyl (3). These compounds were injected into the carotid artery of anesthetized rats, and the ESR spectra of the rat brain were immediately recorded by the use of an L-band ESR spectrometer. Based on the spectra obtained, we considered whether or not these spin labels can pass the blood brain barrier and bind to brain tissue components.
自旋标记物(7、10、13、16、22、27)是由吡啶氧基(1)、吡咯氧基(2)和噁唑啉氧基(3)合成的。这些化合物被注入麻醉大鼠的颈动脉中,并使用L波段电子顺磁共振(ESR)光谱仪立即记录大鼠脑部的ESR光谱。根据获得的谱图,我们考虑了这些自旋标记物是否能够穿透血脑屏障并与脑组织成分结合。
