Description
「殺微生物脂質」は、ウイルス及び/又は細菌及び/又は真菌を殺すことの出来る脂質を意味する。上記のように、そのような脂質は公知であり、殺細胞効果も有することが見出されている。ウイルスを殺すとは、前記脂質に効果的に暴露されたウイルスが細胞に感染出来なくすること、即ちそのウイルスが、その遺伝材料がその中で再生産され得る細胞の中に遺伝材料を導入出来なくすることを意味する。細菌又は細胞を殺すとは、前記脂質に効果的に暴露された細菌又は細胞が、生命の基本的機能を実行出来なくすること;特に細菌又は細胞が、細胞の生理的完全性を維持するために必要な栄養素を取得出来なくすることを意味する。特許請求の範囲及び本明細書の説明に見られるように、前記脂質が同様に強力な殺真菌効果を有することを想像することは、意図され、及び正当と考えられる。
R1、R2及びR3は、C6~C22脂肪酸(-OCO-C5-21H11-43)、ポリオキシエチレングリコール(PEG)((-O-CH2-CH2-)n-H)ポリマー及び水素からなる群から独立して選択され、但し1つ以上のC6~C22脂肪酸及び1つ以上のPEG基を有する)
で表されるポリオキシエチレングリセリドを含有する。
製剤は、実施例1、2及び3の通りに、鼻、咽頭、喉頭、洞、眼球、口腔、外耳道、外耳等の感染を予防及び/又は対抗するための、鼻スプレー及び耳点滴剤として使用されるように調製される。しかしながら、モノカプリン0.15-0.5%及びモノラウリン0.15-0.5%の混合物に代えて、モノカプリン0.5-1%のみ又はモノラウリン0.5-1%のみが添加される。
本発明の製剤は、Staphylococcus aureus (ATCC 25923)、Streptococcus pneumoniae (ATCC 49619)、Haemophilus influenza (NCTC 8468)の3つの細菌株に対して試験された。これらの細菌は、寒天を敷いたペトリ皿状に薄層状に展開された。2枚のプレートを、各製剤20μLで湿らせた。細菌を37℃で24時間培養した。H. influenzae及びS. pneumoniaeはCO2下で培養したが、S. aureusは通常大気下で培養した。結果の読取りは、24時間後に行われた。
対照:メトキシポリエチレングリコール(mPEG)95%及びエタノール5%
試験1:モノカプリン0.15%、モノラウレート0.35%、mPEG94.5%及びエタノール5%
試験2:モノカプリン0.15%、モノラウレート0.35%、mPEG95.5%及びエタノール4%
試験3:モノカプリン0.15%、モノラウレート0.35%、mPEG97.5%及びエタノール2%
試験4:モノカプリン0.15%、モノラウレート0.35%、mPEG98.5%及びエタノール1%
対照寒天プレートでは強力な増殖が見られた。一方、試験1、2、3及び4は、以下のような結果になった。
Staphylococcus aureus =それぞれ17 mm; 19 mm; 18.9 mm; 15.3 mm
Streptococcus pneumoniae =それぞれ7.9 mm; 8.4 mm; 15.4 mm; 14.1 mm
Haemophilus influenza =それぞれ8.0 mm; 8.5 mm; 7.2 mm; 11.0 mm
