A new series of heterocyclic derivatives with a 1,7,7-trimethylbicyclo[2.2.1]heptane fragment were designed, synthesised and biologically evaluated. These derivatives showed antiviral activity against Marburg and Ebola pseudotype viruses, and their activities were closely related to their lysosomotropic effect.
A new series of heterocyclic derivatives with a 1,7,7-trimethylbicyclo[2.2.1]heptane fragment was designed, synthesised and biologically evaluated. Synthesis of the target compounds was performed using the Cu(I) catalysed cycloaddition reaction. The key starting substances in the click reaction were an alkyne containing a 1,7,7-trimethylbicyclo[2.2.1]heptane fragment and a series of azides with saturated nitrogen-containing heterocycles. Some of the derivatives were found to exhibit strong antiviral activity against Marburg and Ebola pseudotype viruses. Lysosomal trapping assays revealed the derivatives to possess lysosomotropic properties. The molecular modelling study demonstrated the binding affinity between the compounds investigated and the possible active site to be mainly due to hydrophobic interactions. Thus, combining a natural hydrophobic structural fragment and a lysosome-targetable heterocycle may be an effective strategy for designing antiviral agents. The synthesis of a new series of heterocyclic derivatives with a 1,7,7-trimethylbicyclo[2.2.1]heptane fragment is reported. These derivatives showed antiviral activity against Marburg and Ebola pseudotype viruses, and the activities of the derivatives were closely related to their lysosomotropic effect.image
