【発明の属する技術分野】
本発明は抗真菌剤に好適な、新規含硫黄複素環化合物に関する。
【0002】
【従来の技術】
水虫に代表される表在性真菌症は、生活が西洋化して靴の着用時間が増加したのに相まって、未だに確実な治療法及び治療薬が見いだされていないこともあり、現代に於ける克服されていない疾病の一つに数えられている。その為、抗真菌作用について、多くの化合物がスクリーニングをかけられた。しかしながら、in vitro或いは動物レベルに於いて活性が見いだされた物質でも、実際の臨床段階においてはドロップアウトするものが少なくなく、満足いく結果は今のところ得られたものは極めて少ない。即ち、新規の抗真菌作用を有する母核の発見が待たれていた。この様な状況は、表在性真菌に止まらず、カンジダ・アルビカンスやアスペルギルス・ニガー等の深在性真菌症に至っては毒性が極めて高く、効果がわずかでしかない、アンホテリシンBを使わざるを得ない極めて深刻な状況にある。即ち、新規母核を有する抗真菌剤の開発が望まれていた。
【0003】
一方、後記一般式(I)に表される化合物は、何れも文献未記載の化合物であり、従って、この様な化合物が優れた抗真菌作用を有することは全く知られていなかった。
【0004】
【発明が解決しようとする課題】
本発明は、この様な状況下に為されたものであり、抗真菌作用を有する新規母核の化合物を見いだすことを課題とする。
【0005】
【課題の解決手段】この様な状況に鑑みて、本発明者らは抗真菌作用を有する新規母核の化合物を求めて鋭意研究努力を重ねた結果、一般式(I)に表される化合物又は生理的に許容されるその塩にその様な作用を見いだし、発明を完成させるに至った。以下、本発明について実施の形態を中心に詳細に説明を加える。
【0006】
【化11】
一般式(I)
(但し、式中R1はハロゲン原子及び炭素数1〜4のアルキル基から選ばれる基を0〜2個有する、チエニル基又はチアゾリル基を表し、R2は炭素数1〜4のアルキル基を表し、R3、R4、R5はそれぞれ独立に炭素数1〜4のアルキル基又はフェニル基を表すが、R3、R4又はR5の何れかはフェニル基を表す。)
【0007】

本発明の一般式(II)に表される化合物は、一般式(I)に表される化合物の重要中間体である。このものをウィティッヒ反応に付し、カルボニル基の酸素原子をメチレン基に変換することにより、一般式(I)に表される化合物へと変換することができる。式中のR3、R4、R5はそれぞれ独立に炭素数1〜4のアルキル又はフェニル基を表す。これらの内特に好ましいものは、これら3つの何れかがフェニル基のものである。これは立体的な歪みが少なく、しかも抗真菌作用が強いからである。この化合物は反応式1に示す如く、チオフェン又はチアゾール乃至はそのハロゲン化物、アルキル化物をルイス酸の存在下アセチル化ししかる後にこのアセチル基のメチルの水素原子をハロゲン原子で置換し、このものと対応するアミンとをアルカリ存在下、縮合する事により製造できる。これらの化合物は何れも文献未記載の新規化合物である。又、これら一般式(II)に表される化合物の好適な具体例としては、例えば、2,4−ジメチル−5−[2−{N−(4−(1−メチル−1−フェニルエチル)ベンジル)−N−メチルアミノ}アセチル]チアゾール(化合物5)、3−[2−{N−(4−(1−メチル−1−フェニルエチル)ベンジル)−N−メチルアミノ}アセチル]チオフェン(化合物6)、2,5−ジクロロ−3−[2−{N−(4−(1−メチル−1−フェニルエチル)ベンジル)−N−メチルアミノ}アセチル]チオフェン(化合物7)、2−[2−{N−(4−(1−メチル−1−フェニルエチル)ベンジル)−N−メチルアミノ}アセチル]チオフェン(化合物8)が例示できる。

BACKGROUND OF THE INVENTION
The present invention relates to a novel sulfur-containing heterocyclic compound suitable for an antifungal agent.
[0002]
[Prior art]
Superficial mycosis, such as athlete's foot, has been overcome in the present age, because there are still no reliable treatments and drugs available, coupled with the fact that life has become westernized and shoe wear has increased. It is counted as one of the diseases that have not been done. Therefore, many compounds have been screened for antifungal activity. However, there are not many substances that have been found to be active in vitro or at the animal level but drop out in the actual clinical stage, and very few results have been obtained so far. That is, the discovery of a mother nucleus having a novel antifungal action has been awaited. This situation is not limited to superficial fungi, but amphotericin B, which is extremely toxic and has little effect on deep fungal diseases such as Candida albicans and Aspergillus niger, must be used. There is no extremely serious situation. That is, development of an antifungal agent having a novel mother nucleus has been desired.
[0003]
On the other hand, any of the compounds represented by the general formula (I) to be described later is a compound not described in any literature, and therefore it has not been known at all that such a compound has an excellent antifungal action.
[0004]
[Problems to be solved by the invention]
The present invention has been made under such circumstances, and an object of the present invention is to find a novel mother nucleus compound having an antifungal action.
[0005]
SUMMARY OF THE INVENTION In view of such circumstances, the present inventors have intensively studied for a new mother nucleus compound having an antifungal action, and as a result, the compound represented by the general formula (I) Alternatively , the inventors have found such an action for physiologically acceptable salts thereof and have completed the invention. Hereinafter, the present invention will be described in detail with a focus on embodiments.

(1) Compound represented by general formula (II) of the present invention The compound represented by general formula (II) of the present invention is an important intermediate of the compound represented by general formula (I). By subjecting this to a Wittig reaction and converting the oxygen atom of the carbonyl group into a methylene group, the compound can be converted into a compound represented by the general formula (I). R3, R4 and R5 in the formula each independently represent an alkyl or phenyl group having 1 to 4 carbon atoms. Of these, particularly preferred are those in which any one of these three is a phenyl group. This is because there is little steric distortion and strong antifungal action. In this compound, as shown in Reaction Scheme 1, thiophene or thiazole or its halide or alkylated product is acetylated in the presence of Lewis acid, and then the methyl hydrogen atom of this acetyl group is replaced with a halogen atom. It can be produced by condensing the amine to be produced in the presence of an alkali. These compounds are all novel compounds not described in any literature. Further, suitable specific examples of the compound represented by the general formula (II) include, for example, 2,4-dimethyl-5- [2- {N- (4- (1-methyl-1-phenylethyl)]. Benzyl) -N-methylamino} acetyl] thiazole (compound 5), 3- [2- {N- (4- (1-methyl-1-phenylethyl) benzyl) -N-methylamino} acetyl] thiophene (compound 6), 2,5-dichloro-3- [2- {N- (4- (1-methyl-1-phenylethyl) benzyl) -N-methylamino} acetyl] thiophene (compound 7), 2- [2 -{N- (4- (1-methyl-1-phenylethyl) benzyl) -N-methylamino} acetyl] thiophene (Compound 8) can be exemplified.

Antibacterial test (measurement of growth inhibitory concentration)
The antifungal action of the compounds of the present invention on trichophyton was determined. That is, Trichophyton mentagrophytes (T.mentagrophytes TIMM1189) is cultured in advance on a slope of Sabouraud's agar medium at 27 ° C. for 2 weeks to sufficiently produce conidia. This is washed with a sterilized physiological saline containing 0.05 wt / vol% of Tween 80 while rubbing with a platinum loop to float the conidia. This was filtered through two layers of gauze and only the conidia were taken out in a form floating in physiological saline. The concentration of conidia was adjusted to 10 5 cells / ml to obtain a test bacterial cell solution. On the other hand, 4 mg of Compound 1 was taken, and 1 ml of dimethyl sulfoxide was added to make a stock solution, which was successively diluted 2-fold with dimethyl sulfoxide to prepare a diluted drug solution. Add 175 μl of Sabouraud dextrose medium, 5 μl of the drug solution, and 20 μl of the test bacterial solution to each well of a 96-well microplate for tissue culture, mix well, then incubate at 27 ° C. for 1 week to completely prevent growth. The minimum concentration was searched and used as the minimum growth inhibitory concentration. The results are as follows: Compound 1 hydrochloride is 1 μg / ml, Compound 2 hydrochloride is 0.0625 μg / ml, Compound 3 hydrochloride is 0.125 μg / ml, and Compound 4 hydrochloride is 0 0.03 μg / ml.
