Preparation and antiviral activity of some new C3- and CS-symmetrical tri-substituted triazine derivatives having benzylamine substituents

Abstract

We report the preparation of new C3- and CS-symmetrical molecules constructed on a triazine (TAZ) template. Anti-herpes simplex virus type 1 (anti-HSV-1) and cytotoxic activities against Vero cells of synthesized TAZ derivatives were evaluated. The results suggested that the presence of an electron-donating group(s) on the benzene ring in benzylamine groups on the TAZ template is an important structural factor for expressing a high level of anti-HSV-1 activity and low cytotoxicity for these C3 types of TAZ derivatives. Among the tested TAZ derivatives, compounds 4f and 7h showed the highest anti HSV-1 activities (EC50=0.98 and 1.23µM, respectively) and low cytotoxic activities to Vero cells (50% cytotoxic concentration (CC50)=292.2 and >200µM, respectively).
