| Questions And Answer | Back Directory | [Description]
Pyrimidone(4-Hydroxypyrimidine) is the name given to either of two heterocyclic compounds with the formula C4H4N2O: 2-pyrimidone and 4-pyrimidone. The compounds can also be called 2-hydroxypyrimidine or 4-hydroxypyrimidine respectively, based on a substituted pyrimidine, or 1, 3-diazine, ring. 4-pyrimidinone is an important bioactive molecule with various biological activities such as anti-virus, anti-tumor, induction of interferon production and immune regulation. |
