RESUMO
As one of our projects, we here report some new molecular modifications of 2,4,6-trichloro-1,3,5-triazine (TCTAZ: 1) to symmetrical 2,4,6-trialkoxy- or 2,4,6-triaryloxy-substituted 1,3,5-triazine (TAZ) molecules, as well as the results of anti-herpes simplex virus type 1 (anti-HSV-1) activity evaluation of synthesized 2,4,6-trisubstituted TAZ derivatives. Among the tested 2,4,6-trisubstituted TAZ derivatives, we reconfirmed that a C3-symmetrical TAZ derivative, 4e, shows the highest level of anti-HSV-1 activity with a good selectivity index. In this paper, we also report the results of the preparation of newly targeted TAZ derivatives and the structure-activity relationships (SARs) of these trialkoxy-substituted TAZ derivatives and related compounds. The sugar recognition properties of C3-symmetrical TAZ derivative 4e are also described.

We describe the synthesis and results of biological evaluation of newly designed 2,4,6-trisubstituted symmetrical 1,3,5-triazine (TAZ) derivatives. Among the tested trisubstituted TAZ derivatives, some CS-symmetrical alkoxy-amino-substituted TAZ derivatives, including 7ggp and 6dpp, showed significant antiviral activity against herpes simplex virus type 1 (HSV-1). The compound with the highest level of antiviral activity was C3-symmetrical trialkoxy-TAZ derivative 4bbb, which showed a considerably high selectivity index (IC50/EC50=256.6). The structure-activity relationships for anti-HSV-1 activity of the tested 2,4,6-trisubstituted TAZ derivatives are also described.
