Abstract: A series of 1,3-disubstituted ureas containing a bicyclic lipophilic group ofnatural origin were synthesized by the reactions of bicyclo[2.2.1]heptane-2-ylisocyanate with amines in yields of up to 82% and by the reactions ofbicyclo[2.2.1]heptan-2-amine and 1,7,7-trimethylbicyclo[2.2.1]heptan-2-aminewith 1,1'-carbonyldiimidazole in yields of up to 94%. The synthesized ureas arepotent inhibitors of RNA virus replication and soluble epoxide hydrolase.
