摘要: 设计并合成了一类新型的碱基与糖环简化的cADPR类似物。该化合物通过Cu(I)催化的Huisgen环加成反应构建三氮唑碱基, 并采用微波辅助法完成分子内的环合反应。初步的生物活性结果表明北区和南区糖环如果用醚链替换可保持化合物活性, 而北区糖环如果用碳链替换则会导致活性消失。

Abstract: New cADPR mimic 5 that integrates the simplified nucleobase and ribose was designed and synthesized by using Cu(I)-catalyzed Huisgen [3+2] cycloaddition to build the simplified triazole nucleobase and microwave-assisted reaction to carry out intramolecular pyrophosphorylation. Primary biological investigation showed that the introduction of an ether strand to replace northern and southern riboses could retain calcium inducing activity, but the introduction of a carbon strand to replace the northern ribose could lead to decreased activity.

Key words: cADPR, Click chemistry, Microwave-assistance, Synthesis
