Description
本発明は、アルカンジオールと、多価不飽和脂肪酸、より詳細にはオメガ−3およびオメガ−6脂肪酸とのエステル、ならびにそれを含有する医薬組成物および化粧料組成物、それを製造するための方法および、特にアクネまたは脂漏性皮膚炎を治療するためのその使用に関する。
アルカンジオールは化粧料または農業食品などの多くの分野において使用されている化合物である。アルカンジオールの静菌性から、防腐剤としての使用を特に挙げることができる。それ故に、アルカンジオールは、真菌および細菌の定着を抑制し、多くの化粧料または農業食品の保護を促すための手段となる(Faergemann J, Fredriksson T. Sabouraudia 1980; 18, 287-293)。これらのジオールは広範囲の活性を有し、真菌およびグラム陽性菌の種に対して特に効果がある(Harb NA, Toama MA. Drug Cosmet Ind: 1976, 118, 40)。さらに、微生物には獲得耐性がほとんどないことから、アルカンジオールは、特に黄色ブドウ球菌(Staphylococcus aureus)に対する、抗耐性戦略の開発において重要な手段となり得る(Faergemann J, Hedner T, Larsson P: 2005, 85, 203-205; WO2004/112765号公報)。最後に、アルカンジオールの耐性が非常に優れていることから、アルカンジオールは頻繁に数パーセントを超える用量で使用することができる。

mは0、1、2、または3であり、および

1.1.一般的方法A:不飽和脂肪酸から
前記不飽和脂肪酸をN2循環下で20ml無水CH2Cl2に溶解する。次いで、カルボジイミド(カップリング剤)(1.1当量)およびジメチルアミノピリジン(0.5当量)を直接加える。その媒質を室温で5〜10分間攪拌した後、前記ジオール(5当量)を加える。その媒質を、光を避けてN2下で18時間激しく攪拌する。その後、その有機相をCH2Cl2で抽出して、飽和NaCl溶液で洗浄し、MgSO4で乾燥させ、濾過し、濃縮する。

3.1.本発明の化合物に対するP.アクネスリパーゼの作用の研究
前記ジオールは、以下の一般式(II)で表されるものである:
最小発育阻止濃度(MIC)は、液体培地において測微法を用いて決定する。培養培地(Trypcase Soy Broth)での試験生成物の連続1/2希釈は96ウェルマイクロプレート中で行い最終量0.1mlにする。それらのウェルに、およそ1×107CFU/mlに力価測定された細菌懸濁液0.01mlを接種する。それらのマイクロプレートを最適増殖条件でインキュベートし、MICを視覚的に読み取る。
試験溶液と細菌懸濁液との接触後に残存するコロニー形成単位(CFU)を計数することにより、細菌の致死率を経時的に評価することによって1,2−オクタンジオールの抗菌活性の速度論を研究した。
PUFAの抗炎症作用を、PMA/A23187により刺激を受けたヒトケラチノサイト(HaCaT)において試験した。得られた結果を図3、図4A、図4B、および図4Cに示す。
HaCaT細胞を96ウェルプレートにおいてPUFAの存在下で24時間インキュベートし、洗い流した後、PMA/A23187により刺激する。6時間の刺激後に上清を回収し、OptEIA(商標)ELISA kit (BD Pharmingen)を使用してIL8を定量する。
HaCaTケラチノサイトを24ウェルプレートにおいて5%CO2雰囲気下、1μCi[3H]AAの存在下で18時間インキュベートした。ケラチノサイトの炎症応答を変調するPUFAの能力を検証するために、[3H]標識したHaCaT細胞をPUFAで24時間前処理し、洗い流した後、500nM PMAおよび1μM A23187で5時間刺激する。培養培地中のHaCaT細胞により放出された[3H]AAおよび代謝産物をカラムクロマトグラフィーにより抽出する。その溶出液をN2下で蒸発させる。乾燥残留物をメタノールに溶解し、事前に100℃で1時間活性化した薄層シリカプレート上に置く。その際、展開溶媒は酢酸エチル/水/イソオクタン/酢酸(110:100:50:20、v/v)混合物の有機相である。[3H]AAおよび代謝産物(6−ケト−プロスタグランジン F1α、6k−PGF1α、プロスタグランジン(PG) FαE2D2、トロンボキサン(TX)B2、ロイコトリエン(LT)B4、C4、D4)をBerthold社TLCスキャナーにより確認する。
