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.

Synthesis and SAR studies of the title compounds have resulted in the identification of structural and physicochemical parameter (Vw) contributing for antiarrhythmic activity. Among the two most promising compounds 3a & 3b, the 3a has shown antiarrhythmic activity comparable to quinidine.
