New analogues of acyclovir--synthesis and biological activity.

New acyclovir esters with peptidomimetics were synthesized and evaluated in vitro for their antiviral activity against the replication of Herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2). The influence of peptidomimetics containing oxazole and thiazolyl-thiazole moieties on the antiviral activity is also reported. The esters were synthesized using the coupling reagents N-ethyl-N'-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC) and N,N-dimethyl-4-aminopyridine (DMAP) as a catalyst.
