Description: Antiviral pyrimidinedione derivatives and process for the preparation thereof Field of the invention The present invention relates to novel pyrimidinedione derivatives or pharmaceutically acceptable salts thereof which are useful as antiviral agents, especially for treatment of AIDS, and process for the preparation thereof. Description of the prior art Nowadays, there are about 15 chemotherapeutic agents for AIDS which were approved by the FDA. It has been known that such chemotherapeutic agents have medical action mechanisms to inhibit replication of AIDS virus. However, they also have drug tolerance and undesirable side effects due to their toxicity. In order to solve these problems, many researches have been carried out to develope new antiviral chemotherapeutic agents with strong antiviral activity as well as lower toxicity. Much researches to develop new antiviral agents for treatment of AIDS have been focused on pyrimidinedione derivatives, and thus the present inventors have synthesized various new pyrimidinedione derivatives by introducing homocarbocyclic groups to the N-l position of pyrimidinedione derivatives, which compounds were applied for patent (see, WO97/30979, US patent 5,922,727), and they continued synthesis and evaluation of new derivatives prepared by introducing new homocarbocyclic groups, aryl and heteroaryl substituents, alkyl and aryl carbonylmethyl groups to the pyrimidinedione derivatives and studied their pharmacological effects. As the result, the inventors have found that the newly synthesized derivatives by the present invention have unexpectedly strong anti-HIV (Human Immunodeficiency Virus) activity as well as very low toxicity. Summary of the invention Accordingly, an object of the present invention is to provide new pyrimidinedione derivatives of the following formula (I) or pharmaceutically acceptable salts thereof which have strong antiviral activity against HIV. wherein R represents cyclopropyl; cyclobutyl; cyclohexyl; unsubstituted or mono-, di- or tri-substituted phenyl with a group selected from hydroxy, Cι~C alkyl, Cι-C 4 alkoxy, halogen, trifluoromethyl, cyano and amino; 1- or 2-naphthyl; 9-anthracenyl; 2-anthraquinonyl; unsubstituted or substituted pyridyl with a group selected from Cι-C alkyl, G-C 4 alkoxy, cyano and halogen; 2-, 3- or 4-quinolinyl; oxiranyl; 1-benzotriazolyl; 2-benzoxazolyl; furanyl substituted with Cι-C 4 alkoxy carbonyl; Cι-C alkylcarbonyl; or benzoyl, Ri represents halogen or Cι-C alkyl, R2 and R3 represent independently hydrogen or Cι-C 4 alkyl, X represents oxygen atom, and Y represents oxygen atom, sulfur atom or carbonyl.

Physical properties of the compounds prepared by the above examples are s follows: Activity and Toxicity Anti-HIV activity tests in vitro of the compounds according to the present invention were performed as described in J. Med. Chem, 34, 357, 1991. Inhibition by the compounds of virus-induced cytotoxic effect in MT-4 cells was measured as follows. MT-4 cells were suspended in culture media at 2.5xl0 5 cells/ml and infected with 1000 CCID50 ( 50% cell culture infective dose ) of HIN. Immediately after virus infection, 100 ti of cell suspension was brought into each well of a flat-bottomed microtitray containing various concentrations of the test compounds. After 4 or 5 days incubation at 37°C, efficacy of the compounds was determined by the MTT method. Cytotoxicity of the compounds was assessed in parallel with their antiviral activity, based on viability of mock-infected host cells as determined by the MTT method. The results are shown in the following table. Usefulness of the invention The present compounds have strong anti-HIN activity as well as very low toxicity, and thus they are expected to be used as potent antiviral agents.
