Pyrimido[1,2-b]-1,2,4,5-tetrazin-6-ones as HCMV protease inhibitors: a new class of heterocycles with flavin-like redox properties

Bioorg Med Chem Lett. 2003 Oct 20;13(20):3483-6. doi: 10.1016/s0960-894x(03)00789-3.

Abstract

The synthesis and biological activity of pyrimidotetrazin-6-ones against HCMV protease is described. The mechanism of action for these inhibitors is the oxidation of several cysteine residues to generate cross-linked enzyme.
