Abstract
Efficient conditions for the synthesis of nitrogen-containing heterocyclic derivatives of (1,3)(+)-camphoric acid were selected. A series of heterocyclic compounds based on (+)-camphoric acid bearing pharmacophoric fragments was synthesized using the developed methodology. The compounds were tested for their antiviral activity against SARS-CoV-2 and H1N1 influenza viruses, and efficient inhibitors were identified that are of significant interest for further studies. The stability of the compounds and pharmaco-kinetics of the leader compound were studied when administered intragastrically and intramuscularly to mice at a dose of 200 mg kg using the HPLC-MS/MS method.
