lyxo-furanosyltubercidin analogues as well as the newly discovered erythro-furanosyltubercidin analogues, designed to prevent 5'-O-phosphorylation and associated toxicities, were tested for their analgesic activity in the rat formalin paw model. Described herein are the synthesis, enzyme inhibition structure-activity relationships (SARs) of erythro-furanosyltubercidin analogues, and SARs of analgesic activity of various
腺苷是一种内源性神经调节剂,当在中枢和周围神经系统中产生时,具有抗惊厥,抗炎和镇痛作用。然而,剂量限制的心血管副作用困扰着使用腺苷受体激动剂的努力。作为替代方案,我们探索了腺苷激酶抑制剂(AKIs)作为潜在的抗癫痫药的用途,并证明了在没有明显的心血管副作用的情况下腺苷受体介导的治疗作用。这些活性与以部位和事件特异性方式抑制AK导致的细胞外腺苷浓度升高有关。几种基于结核菌素的AKI,包括核糖和呋喃呋喃糖基结核病类似物,以及新近发现的赤呋喃呋喃糖基结核病类似物,旨在预防5' 在大鼠福尔马林爪模型中测试了-O-磷酸化作用和相关的毒性。在此描述的是赤型-呋喃糖基tubercidin类似物的合成,酶抑制结构-活性关系(SAR),以及各种类型的AKI的镇痛活性。还报道了AKI铅19d(GP3966)的表征,这是一种口服生物利用化合物(狗中F%= 60%),具有广谱镇痛活性(ED50 <或= 4 mg /
