solvent-derived dioxane molecules in the hydrophobic binding pocket. A bis-dioxane antiviral agent was designed by linking the two dioxane molecules with a three-carbon chain having R,R connecting stereochemistry, and a stereospecific synthesis was performed. This resulted in an effective antiviral agent that inhibited Sindbis virus replication with an EC(50) of 14 microM. The synthesis proceeded through
Sindbis病毒衣壳蛋白的晶体结构在疏水结合口袋中包含一个或两个溶剂衍生的二恶烷分子。通过将两个二氧六环分子与具有连接立体化学的R,R的三碳链连接,设计了双二氧六环抗病毒剂,并进行了立体特异性合成。这导致了一种有效的抗病毒剂,以14 microM的EC(50)抑制了Sindbis病毒的复制。合成过程通过中间体(R)-2-羟甲基-[1,4]二恶烷进行,该化合物出乎意料地证明是比目标化合物更有效的抗病毒剂,其EC(50)为3.4 microM作为抑制剂证明了这一点。 Sindbis病毒复制。两种化合物在浓度为1mM的未感染BHK细胞中均无细胞毒性。
