## Background
The present invention relates to novel phosphonate nucleotide compounds. More specifically, the present invention relates to phosphonate nucleotide compounds and their salts, and hydrates and solvates thereof, which have antiviral activity and are useful as medicaments.

Viral Infectious diseases are recognized as serious clinical problems. In order to therapeutically treat such diseases, attempts have been made to develop medicaments having antiviral activity, while exhibiting no growth inhibitory activity against normal cells systems. For example, extensive recent researches has been focused on phosphonate nucleotides as selective antiviral agents. More specifically, 9-(2-phosphonylmethoxy) ethyladenine (PMEA), 9-(2-phosphonylmethoxy)ethyl-2,6-diaminopurine (PMDAP) and the like are reported as being effective against herpes simplex type 1 and 2 viruses (HSV-1 and HSV-2), human immunodeficiency virus (HIV), and human hepatitis B virus (HBV) (Yokota et al., Antimicrob. Agents Chemother., 35, 394, 1991; Votruba et al., Mol. Pharmacol., 32, 524, 1987).

However, these known phosphonate nucleotides have problems of insufficient safety because they have toxicities against living bodies, whose typical example includes bone marrow cell growth inhibition, and have potential mutagenicities (Antiviral Research, 16, 77, 1991). In addition, there is another problem that they are not orally absorbable (De Clercq et al., Antimicrob. Agents Chemother., 33, 185, 1989), and their administration routes are limited to parenteral routes such as intravenous or intramuscular injection to achieve blood concentrations essential for exhibiting pharmacological effects. Therapeutic treatment by parenteral administration can hardly be carried out for patients other than inpatients, and is not preferably applied to treatments of AIDS, hepatitis B virus infection and the like which require long-term care.

The inventors of the present invention found that particular ester derivatives of phosphonate nucleotides have high oral absorbability (EP 632,048 A1). However, they have not yet been clinically developed.

An object of the present invention is to provide an antiviral agent having no toxicity such as growth inhibition against bone marrow cells or mutagenicity. Another object of the present invention is to provide an antiviral agent having excellent oral absorbability.

The inventors of the present invention conducted various studies to achieve the foregoing objects, and as a result, they found that particular 2-amino-6-arylthiopurinephosphonates, which are not specifically disclosed in the aforementioned EP 632,048 A1, have high antiviral activities, and that these compounds are safer to living bodies than conventionally proposed compounds and have excellent oral absorbability. The present invention was achieved on the basis of these findings.

The present invention thus provides phosphonate nucleotide compounds represented by the following formula (I) and their salts, and hydrates and solvates thereof: ##STR2## wherein R.sup.1 represents hydrogen atom, a C.sub.1 -C.sub.6 alkoxy group, a C.sub.1 -C.sub.4 alkoxy group substituted with one or more halogen atoms, a halogen atom, amino group, or nitro group; R.sup.2 and R.sup.1 independently represent hydrogen atom, a C.sub.1 -C.sub.2 2 alkyl group, an acyloxymethyl group, an acylthioethyl group, or an ethyl group substituted with one or more halogen atoms; R.sup.4 represents hydrogen atom, a C.sub.1 -C.sub.4 alkyl group, a C.sub.1 -C.sub.4 hydroxyalkyl group, or a C.sub.1 -C.sub.4 alkyl group substituted with one or more halogen atoms; and X represents a carbon atom or a nitrogen atom.

According to another aspect of the present invention, there are provided a pharmaceutical composition comprising a substance selected from the group consisting of the aforementioned compound and its salt, and a hydrate and a solvate thereof together with a pharmaceutically acceptable additive; and an antiviral agent comprising as an active ingredient a substance selected from the group consisting of the aforementioned compound and its salt, and a hydrate and a solvate thereof.

According to further aspect of the present invention, there are provided a use of a substance selected from the group consisting of the aforementioned compound and its salt, and a hydrate and a solvate thereof for the manufacture of the aforementioned pharmaceutical composition; and a method for therapeutic treatment of a viral infectious disease which comprises a step of administering to a mammal including a human an effective amount of a substance selected from the group consisting of the aforementioned compound and its salt, and a hydrate and a solvate thereof.
