Synthesis and Antiviral Activity of Homodimers of 1,2,3-Triazolyl Nucleoside Analogues Based on Quinazoline-2,4-dione
摘要
Abstract
By covalent binding of 1,2,3-triazolyl nucleoside analogues by a polymethylene chain at the N3 atoms, a series of homodimers was synthesized, in which nucleic bases are replaced by quinazoline-2,4-dione moieties connected to the β-D-ribofuranose residues by 1,2,3-triazolylbutyl linkers. Screening of in vitro antiviral activity against influenza A (H1N1) and Coxsackie B3 viruses revealed a lead compound that showed high antiviral activity (IC50 = 11.6 μM) against influenza A/Puerto Rico/8/34 (H1N1) virus and a lead compound that exhibited high antiviral activity (IC50 = 12.2 μM) against enterovirus Coxsackie B3.
