A water-soluble spin probe, disodium 4-[(4,8-sulfonatooxy-2-naphthyl)thioureylene]-2,2,6,6-tetramethyl-1-piperidinyloxyl (TEMPO-T) was newly synthesized and characterized comparing with several different TEMPO derivatives from the view point of a possibility of utilization in the liposomal studies. Of TEMPO derivatives studied, TEMPO-T was the best probe because of the high water solubility, the less lipophilicity, the less leakiness from liposome, and the reliable stability to both temperature and pH changes.
从能否用于脂质体研究的角度出发,新合成了一种水溶性自旋探针--4-[(4,8-磺酸基氧基-2-萘基)硫脲基]-2,2,6,6-四甲基-1-哌啶环氧二钠盐(TEMPO-T),并与几种不同的 TEMPO 衍生物进行了比较。在所研究的 TEMPO 衍生物中,TEMPO-T 是最好的探针,因为其水溶性高、亲油性低、从脂质体中泄漏的可能性小,而且对温度和 pH 值变化都具有可靠的稳定性。
