6-AZAURIDINE 2',3',5'-TRIACETATE

Azaribine (2',3',5'-Tri-O-acetyl-6-azauridine) is a potent orotidine monophosphate decarboxylase (OMPD) inhibitor. Azaribine is an antiviral inhibitor of several RNA viruses and inhibits viral genome replication and gene transcription. Azaribine shows broad-spectrum antiviral activity (EC50=3.80 nM-1.73 μM against influenza A and B viruses; EC50=1.62 μM against ZIKV Paraiba). Azaribine, a triacetate salt of Azauridine, has the potential for psoriasis research[1][2].

Azaribine (2',3',5'-Tri-O-acetyl-6-azauridine; 0-2 μM; 48 小时) 对MDCK细胞具有细胞毒性 (MTT: CC50=19.66 μM)[1]。 Azaribine 对 BIRFLU 增殖具有强效抑制作用 (MDCK 细胞: EC50=0.29 μM；A549 细胞: EC50=0.55 μM) [1]。 Azaribine 在 MDCK 细胞后处理期间显示出对季节性 H1N1 和 H3N2 IAV 和 IBV 的抑制作用，EC50 分别为 0.60 μM、0.77 μM、0.80 μM[1]。 Azaribine 在 16HBE 细胞的后处理过程中具有抗 NC H1N1 作用，EC50 为 1.58 μM[1]。 Cell Cytotoxicity Assay[1] Cell Line: MDCK cells Concentration: 0-2 μM Incubation Time: 48 h Result: Had cytotoxicity on MDCK cells (CC50=19.66 μM).
