Nowadays, various compounds such as AZT, DDC, DDI and D4T have been used as chemotherapeutic agents of AIDS and have a medical action mechanism with inhibition of the replication of AIDS virus. They also have drug tolerance and undesirable side effects due to their toxicity.
1. In order to overcome these problems, intensive researches have been carried out to develope antiviral chemotherapeutic agents with strong activity and with lower toxicity. Among them, researches have been focused on pyrimidine 6-substituted necleoside compounds. But, N-l substituted homocarbocyclic nucleoside derivatives were not developed as yet.
The present inventors carried out an intensive research on the N-l substituted homocarbocyclic necleoside derivatives and unexpectively found out the facts that the compounds have strong activity against HIVCAIDS, Acquired immunodeficiency syndromes) as well as a lower toxicity.
Accordingly, the present invention relates to new pyrimidinedione derivatives, 6-substituted pyrimidinedione homocarbocyclic nucleosides which are useful as an antiviral agent for treating acquired immunodeficiency syndromes ( AIDS ), and pharmaceutically acceptable salts thereof.

Experimental Example
Antiviral activity and Toxicity test
The anti-HIV assays were based on the inhibition of the virus-induced cytopathic effect in MT-4 cells as a described method in J. Med. Chem, 34, 357, 1991. Briefly, MT-4 cells were suspended in culture medium at 2.5x105 cells/ml and infected with 1000 CCIDso ( 50% cell culture infective dose ) of HIV. Immediately, after virus infection, 100/^ of the cell suspension was brought into each well of a flat-bottomed microtitray containing various concentrations of the test compounds. After a 4 or 5 days incubation at 37°C, the number of viable cells was determined by the 3-(4, 5-dimethylthiazol-2-yl)-2 , 5-diphenyltetrazolium bromide (MTT) method, as disclosed in J . Virol . Methods, 20, 309, 1988. The cytotoxicity of the compounds of the present invention was assessed in parallel with their antiviral activity. It was based on the viability of mock-infected host cells as determined
