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.
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-1 position of pyrimidinedione derivatives, which compounds were applied for patent (see, WO97/30979, U.S. Pat. No. 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.
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.
Another object of the invention is to provide a process for the preparation of the compounds of the general formula (I) or pharmaceutically acceptable salts thereof.
The other object of the invention is to provide pharmaceutical preparations having antiviral activity which contains the compound of the general formula (I) or a pharmaceutically acceptable salt thereof as the active ingredient.
The compounds of the general formula (I) according to the present invention may be prepared by the following reaction scheme 1.
The compounds of the general formula (I) may be prepared by reacting a compound of the general formula (II) with a compound of the general formula (III) in a conventional organic solvent and in the presence of a base.
The base used in the above reaction may include anhydrous sodium bicarbonate, anhydrous sodium carbonate, sodium hydride and anhydrous potassium carbonate.
The organic solvent used in the reaction may include an organic polar solvent such as dimethylformamide, acetonitrile and dimethylsulfoxide.
In addition, a catalyst such as potassium iodide, lithium iodide or the like may be used.
The reaction may be carried out preferably at the temperature of 10˜100° C. for 1–48 hours.
6-substituted pyrimidinedione derivatives of the formula (II) used in the present invention may be prepared as described in WO 93/02044 and WO 95/18109, or by using a similar method thereto.
The compounds of the formula (I) may form an addition salt with a pharmaceutically acceptable inorganic or organic acid or base; for example, bases such as salts of alkali metal and alkaline earth metal including sodium, potassium, magnesium and calcium; inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid and nitric acid; organic acids such as formic acid, acetic acid, propionic acid, succinic acid, citric acid, maleic acid, glycolic aicd, lactic acid and malonic acid; amino acids such as serine, cysteine, cystine, asparagine, glutamine, lysine, arginine, leucine and proline; sulfonic acids such as methane sulfonate, ethane sulfonate, benzene sulfonate and toluene sulfonate.

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 2.5×105 cells/ml and infected with 1000 CCID50 (50% cell culture infective dose) of HIV. Immediately after virus infection, 100 μl 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-HIV activity as well as very low toxicity, and thus they are expected to be used as potent antiviral agents.
