A novel series of diethyl 4-[(5-substituted-1,3-dioxo-1H-benzo[de]isoquinolin-2(3H)-yl)-methyl]-1H-1,2,3-triazol-1-yl}alkylphosphonates designed as analogues of amonafide was synthesized. All phosphonates were assessed for antiviral activity against a broad range of DNA and RNA viruses and several of them showed potency against varicella-zoster virus (VZV) [EC50 (50% effective concentration) = 27.6–91.5 μM]. Compound 16b exhibited the highest activity against a thymidine kinase-deficient (TK−) VZV strain (EC50 = 27.59 μM), while 16d was the most potent towards TK+ VZV (EC50 = 29.91 μM). Cytostatic properties of the compounds 14a–i–17a–i were studied on L1210, CEM, HeLa and HMEC-1 cell lines and most of them were slightly cytostatic for HeLa [IC50 (50% inhibitory concentration) = 29–130 µM] and L1210 cells [IC50 (50% inhibitory concentration) = 14–142 µM].

膦酸盐对
水痘-带状疱疹病毒(VZV)的抗病毒活性[
EC50(50% 有效浓度)= 27.6-91.5 μM]。化合物 16b 对
胸苷激酶缺乏型(TK-)VZV 株的活性最高(
EC50 = 27.59 μM),而 16d 对 TK+ VZV 的活性最强(
EC50 = 29.91 μM)。在 L1210、C
EM、HeLa 和
HMEC-1
细胞系上研究了化合物 14a-i-17a-i 的细胞抑制特性,结果表明大多数化合物对 HeLa [IC50(50% 抑制浓度)= 29-130 µM]和 L1210 细胞 [IC50(50% 抑制浓度)= 14-142 µM]有轻微的细胞抑制作用。
