Synthesis and biological evaluation of symmetrical 2,4,6-trisubstituted 1,3,5-triazine derivatives.

We describe the synthesis and biological evaluation of newly designed 2,4,6-trisubstituted symmetrical 1,3,5-triazine (TAZ) derivatives. Among the tested trisubstituted symmetrical TAZ derivatives, various C3- or CS-symmetrical alkoxy-amino-substituted TAZ derivatives showed significant antiviral activity against herpes simplex virus type 1 (HSV-1) and/or cytotoxic activity against Vero cells. The structure-activity relationships for anti-HSV-1 activity of these symmetrical 2,4,6-trisubstituted TAZ derivatives are also described.
