purine nucleobase-simplified cyclic ADP ribose (cADPR) analogue 6b was synthesized, in which a 1,2,3-triazole-4-amide was constructed, instead of a purine moiety, and the northern ribose was replaced by an ether strand. Compound 6b exhibits calcium release activity in intact T-lymphocytes and indicates that it is a membrane-permeable cADPR mimic. Thus, the cADPR analogue containing 1,2,3-triazole-4-amide
合成了嘌呤核碱基简化的环状ADP核糖(cADPR)类似物6b,其中构造了1,2,3-三唑-4-酰胺,而不是嘌呤部分,而北部核糖被醚链取代。化合物6b在完整的T淋巴细胞中表现出钙释放活性,表明它是膜可渗透的cADPR模拟物。因此,包含1,2,3-三唑-4-酰胺的cADPR类似物为进一步设计cADPR类似物并阐明其结构-活性关系提供了新颖的模板。
