Description

【0001】
【発明の属する技術分野】
本発明は、人類未体験の変種コロナウイルスの感染に伴い発症する重症急性呼吸器症候群(SARS)の予防に関する。
【0002】
【従来の技術】
感染症情報センターの資料によれば、現在有効な消毒方法は、加熱処理がもっとも有効であるが、加熱処理を施せない対象については次亜塩素酸ナトリウムやグルタルアルデヒド、ホルムアルデヒド、ヨードなどが推奨されているが、いずれも刺激性やアレルギー性が高くヒトへの消毒剤としては用いることが出来ない。 用いる事が可能な物質として、消毒用エタノール(80%以上)が上げられるが、消防上の観点や高濃度エタノールによる皮膚刺激反応やアレルギー反応、皮膚の乾燥により実際の取り扱いおよび使用が難しい。 他方塩化ベンザルコニウムやグルクロン酸クロルヘキシジンなどの消毒剤があるが、明確に有効な手段とは報告されていない。
【0003】
【本発明が解決しようとする課題】
従来の技術では、感染を予防する効果が低く、安全性または健康上問題のある手段も多く、有効な消毒法がなく、全世界的な蔓延を招いている。
【0004】
【問題を解決するための手段】
0.01重量%から1.0重量%の2,4,4’−トリクロロ−2’−ヒドロキシジフェニルエーテル(慣用名トリクロサン)または0.1重量%から10.0重量%のエチレングリコールモノフェニルエーテル(慣用名フェノキセトールまたはフェノキシエタノール)または0.01重量%から0.5重量%の3−(4−クロロフェノキシ)1,2−プロパンジオール(慣用名クロルフェネシン)の1種以上を配合してなるコロナウイルスに対する感染を予防する皮膚外用剤および口腔洗浄剤。
【0005】
本発明は、当該重症急性呼吸器症候群(SARS)の原因であるコロナウイルスの変種を死滅不活性化する。一般的にコロナウイルスはエンベロープを有するウイルスであり、本ウイルスは一般的にエーテルに対し感受性のタイプである。このエーテル感受性に着眼し、いわゆる消毒や防腐殺菌剤の中から、エーテル基を有する種類を集め試験を実施した。試験方法は、一般的なウイルス培養溶液に2%重量ウシ胎児血清を補足し、37度にて当該コロナウイルスを培養し、接種1日後、2日後、4日後にウイルスを分離しカウントした。
【0006】
以下実施例をあげて、その効果を説明する。実施例と比較例およびその結果を表1に記載した。比較例には陽性対照として、0.5重量%ホルムアルデヒド水溶液、0.1重量%塩化ベンザルコニウム水溶液、0.1重量%グルクロン酸クロルヘキシジン水溶液を用い、無処置対照としては培養液のみを用いた。実施例は実施例3の0.1重量%トリクロサン液または実施例2の0.5重量%フェノキセトール液、実施例1の0.1重量%クロルフェネシン液のそれぞれの単独溶液と、実施例4の0.1重量%トリクロサンおよび0.5重量%フェノキセトールの混合液および実施例5の0.1重量%クロルフェネシンおよび0.5重量%フェノキセトール混合液を用いた。 実施例の基剤は20重量%エタノールである。
【0007】
その結果、比較例4の無処置対照は接種直後1000万ユニットのウイルスを認めたが、徐々に減少しはじめ、接種4日後に当該ウイルスは死滅した。 比較例では、ホルムアルデヒドの効果がもっとも高く接種30分後から10の4乗ユニットの減少を認め、1日後には死滅した。ついでグルクロン酸クロルヘキシジンの効果が高く、塩化ベンザルコニウムにも若干劣る物の効果を認めた。実施例では実施例3のトリクロサンに高い効果を認め、ついで実施例1のクロルフェネシンが続き、ついで実施例2のフェノキセトールであった。さらに実施例4のトリクロサンおよびフェノキセトールの混合液および実施例5では、接種30分後から10の5乗から10の4乗ユニットの減少を認めホルムアルデヒドに匹敵する相乗効果を認めた。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to the prevention of severe acute respiratory syndrome (SARS) that develops with the infection of a variant coronavirus that has not been experienced by humans.
[0002]
[Prior art]
According to the data of the Center for Infectious Diseases, heat treatment is the most effective disinfection method at present, but sodium hypochlorite, glutaraldehyde, formaldehyde, iodine, etc. are recommended for those that cannot be heat treated. However, none of them is highly irritating or allergic and cannot be used as a disinfectant for humans. Ethanol for disinfection (80% or more) can be used as a substance that can be used, but actual handling and use are difficult due to fire fighting, skin irritation and allergic reactions due to high-concentration ethanol, and drying of the skin. On the other hand, there are disinfectants such as benzalkonium chloride and chlorhexidine glucuronate, but they have not been reported as clearly effective means.
[0003]
[Problems to be solved by the present invention]
The prior art is less effective in preventing infection, has many safety or health problems, lacks effective disinfection methods, and has led to worldwide spread.
[0004]
[Means to solve the problem]
0.01% to 1.0% by weight of 2,4,4′-trichloro-2′-hydroxydiphenyl ether (commonly known as triclosan) or 0.1% to 10.0% by weight of ethylene glycol monophenyl ether ( One or more kinds of common name phenoxetol or phenoxyethanol) or 0.01 to 0.5% by weight of 3- (4-chlorophenoxy) 1,2-propanediol (common name chlorphenesin) are blended. An external preparation for the skin and a mouthwash for preventing infection with coronavirus.
[0005]
The present invention kills and inactivates the variant of coronavirus that causes severe acute respiratory syndrome (SARS). Generally, a coronavirus is an enveloped virus, and the virus is generally of a type that is sensitive to ether. Focusing on this ether sensitivity, a test was conducted by collecting types having an ether group from so-called disinfection and preservative disinfectants. In the test method, a 2% by weight fetal bovine serum was supplemented to a general virus culture solution, the coronavirus was cultured at 37 ° C, and the virus was separated and counted 1 day, 2 days, and 4 days after inoculation.
[0006]
The effects will be described below with reference to examples. Examples and comparative examples and the results are shown in Table 1. As a positive control, a 0.5% by weight aqueous solution of formaldehyde, a 0.1% by weight aqueous solution of benzalkonium chloride, and a 0.1% by weight aqueous solution of chlorhexidine glucuronate were used as positive controls, and only a culture solution was used as an untreated control. . In the examples, the 0.1 wt% triclosan solution of Example 3 or the 0.5 wt% phenoxetol solution of Example 2 and the 0.1 wt% chlorphenesin solution of Example 1 were used alone, respectively. The mixture of 0.1% by weight of triclosan and 0.5% by weight of phenoxetol of Example 4 and the mixture of 0.1% by weight of chlorphenesin and 0.5% by weight of phenoxetol of Example 5 were used. The base in the example is 20% by weight ethanol.
[0007]
As a result, the untreated control of Comparative Example 4 showed 10 million units of the virus immediately after the inoculation, but gradually began to decrease, and the virus died four days after the inoculation. In the comparative example, the effect of formaldehyde was highest and a decrease of 10 4 units was observed 30 minutes after inoculation, and the cells died one day later. Then, the effect of chlorhexidine glucuronate was high, and that of benzalkonium chloride was slightly inferior. In the examples, the triclosan of Example 3 showed a high effect, followed by chlorphenesin of Example 1 and then phenoxetol of Example 2. Further, in the mixed solution of triclosan and phenoxetol in Example 4 and Example 5, a decrease in 10 5 to 10 4 units was observed 30 minutes after inoculation, and a synergistic effect comparable to that of formaldehyde was observed.
