ProTide strategy are known for their ability to increase the biological activity of various nucleosides. A series of such prodrugs of SRO-91, a non-natural ribofuranosyl-1,2,3-triazole C-nucleoside obtained by a synthetic sequence involving an indium mediated alkynylation and a Huisgen cycloaddition, was prepared and the antitumor activity on 3 strains of tumor cells was investigated. Two compounds 9a and
根据 ProTide 策略获得的氨基磷酸酯以其增加各种核苷生物活性的能力而闻名。SRO-91是一种非天然呋喃核糖基-1,2,3-三唑C-核苷,通过铟介导的炔基化和Huisgen环加成的合成序列制备了一系列此类前药,并对3株菌株具有抗肿瘤活性研究了肿瘤细胞。两种化合物9a和9c对两种细胞系(胰腺和肺)表现出有趣的细胞增殖抑制作用(IC 50 = 2.5–12.1 µM)。此外,关于抗病毒活性,另一种带有不同芳基掩蔽基团的氨基磷酸酯14表现出 IC 505 µM 对克里米亚-刚果出血热 orthonairovirus。在这两种情况下,游离的 SRO-91 对这些细胞系均无活性。
