【発明の属する技術分野】
本発明は、逆転写酵素阻害活性を有する化合物および該化合物を含有する逆転写酵素阻害剤に関する。
【0002】
【従来の技術】
近年、後天性免疫不全症候群(acquired immunodeficiency syndrome,AIDS)やヒト成人T細胞白血病(humanadult T cell leukemia,HALT)が世界的に広まり、これらの予防法や治療法の確立が急務とされている。
【0003】
後天性免疫不全症候群はヒト免疫不全ウィルス(human immunodeficiency virus,HIV)によって発症し、ヒト成人T細胞白血病はヒトT細胞白血病ウィルス(human T cell leukemia virus)によって発症することが知られている。これらのウィルスは、RNAをDNAに変換する逆転写酵素を有することを特徴とするレトロウィルスである。
【0004】
このため、これらのレトロウィルスに存在する逆転写酵素の活性を阻害することによって、ウィルスによるAIDS等の発症を防止する研究が種々なされてきた。その結果、今日までに、逆転写酵素阻害活性を有するさまざまな物質が開発されている。例えば、アジドチミジン、ジデオキシシチジン、ジデオキシノシンが逆転写酵素阻害活性を有するAIDS治療薬として認可されている。しかしながら、これらの治療薬は製造コストが高く、副作用が強いという問題がある。

(Test example)
Using the five types of compounds obtained in the examples as samples, a reverse transcriptase inhibitory activity test was performed according to the following procedure.
[0033]
To 30 μl of sample solution of various concentrations, 10 μl of reaction mixture (0.05 M Tris-HCl buffer (pH 8.0), 0.01 MDTT, 0.1 M potassium chloride, 0.006 M magnesium chloride, 2 μg / ml Poly (A ) P (dT) 15 , 0.37 μM 3H-dTTP, 10 μM dTTP, glycerol / water = 25/16), 0.001 U / ml HIV-1 reverse transcriptase solution 10 μl, buffer (50 mM Tris-HCl pH 8.0, 10 μl of 10 mM DTT, 200 mM potassium chloride, 50 v / v% glycerol) was added to make a total volume of 50 μl. After stirring and centrifuging, the mixture was incubated at 37 ° C. for 30 minutes. Thereafter, 20 μl of EDTA was added with ice cooling, and the mixture was stirred and centrifuged. 50 μl of the reaction solution was spotted on an ion exchange cellulose filter, and after drying, washed with 5% disodium hydrogen phosphate (8 times), water (2 times), ethanol (2 times), and diethyl ether (2 times). An ion exchange cellulose filter was placed in a scintillator and measured with a liquid scintillation counter.
[0034]
The sample concentration in the reaction solution was changed in the range of 0.01 to 1,000 μg / ml, and the concentration when the inhibition rate was 50% was defined as IC50. As a result, it was confirmed that the IC50s of the five types of compounds obtained in the examples were all in the range of 100 to 150 μg / ml. Moreover, it was confirmed that all of the five compounds have low toxicity.
[0035]
【The invention's effect】
The compound represented by the general formula (1) has low toxicity and excellent reverse transcriptase inhibitory activity. Therefore, the reverse transcriptase inhibitor of the present invention containing the compound represented by the general formula (1) is useful for the prevention and treatment of diseases involving retroviruses such as AIDS.
