Synthesis of (1S)-(+)-camphor-10-sulfonic acid derivatives and investigations in vitro and in silico of their antiviral activity as the inhibitors of fi lovirus infections

Аннотация

N-Heterocycle-containing (1S)-(+)-camphor-10-sulfonamide derivatives were synthesized. Their antiviral activity against the Ebola and Marburg viruses was estimated using a pseudovirus system based on the vesicular stomatitis virus. The derivatives bearing morpholine and triazole moieties demonstrated the highest inhibitory activity towards the Ebola virus glycoprotein. A moderate activity against the Marburg virus was found for a compound containing the piperidine moiety. A molecular modeling of the interaction between the synthesized derivatives and the binding site of glycoprotein of the Ebola virus was performed.
