R6はDPheであり、
R7はLeuであり、

を有する化合物および医薬的に許容されるその塩を提供する。
本発明の化合物は、当技術分野で既知の方法により調製することができる。以下の例は、式(I)の化合物の調製を示す。
NAB815はオクタノイル−αDab−Thr−DThr−[シクロ−α,γDab−αDab−DPhe−Leu−Abu−αDab−Thr]という構造式を有し、式中、R10のカルボキシ末端Thrは、そのカルボキシル基を介してR4の2,4−ジアミノ酪酸残基(Dab)の4−アミノ基に結合し、相対分子質量は1175.44であるが、該NAB815は、例えば、NAB739などの他のポリミキシン誘導体に関し以前記載された方法論(米国特許第7807637号明細書)を用いた、従来の固相化学により合成することが可能である。C末端のアミノ酸は、固相に予め付着したものとして市販されており、樹脂を酸で開裂するとC末端カルボキシル酸が生じる。
本発明を例示的な方法で示すために以下の例を提供するが、本発明の範囲を限定するものとして考えるべきではない。さらに、試験における化合物の濃度は例示であり、限定と取るべきではない。当業者は、当分野で既知の方法を用いて、医薬的に適切な濃度を定義することができる。倫理行為規範および適切な動物実験方針に従って全ての動物実験を行った。
化学物質源:NAB815硫酸塩(ロット1051607;HPLCによる純度、98.8%)およびオクタノイル−Thr−DSer−[シクロ−α,γDab−αDab−DPhe−Leu−αDab−αDab−Thr]、つまりOA−SEQ ID 2という構造式を有するNAB739硫酸塩(ロット1049851、HPLCによる純度、97.3%)。ポリミキシンB硫酸塩は、シグマアルドリッチ(米国ミズーリ州セントルイス)から入手した(カタログ番号P0972、ロットBCBF8382V;純度、89.3%。)
*リファンピンを欠く場合のMIC値は、三重測定による形式上のMIC値および二重チェッカーボード試験によるMICの一覧である。リファンピン(0.25μg/mL)の存在下でのMIC値は、二重チェッカーボード試験による。(三重測定による)各標的株に対するリファンピンの形式上のMIC(μg/mL)を、標的細菌株の名称の後の括弧内に示す。
毒性およびトキシコキネティクスのin vivo研究を、カニクイザルを用いて行った。動物研究を行った研究所は、実験動物ケア評価認証協会(AAALAC:Association for Assessment and Accreditation of Laboratory Animal Care)により認証されており、米国実験動物福祉局(OLAW:Office of Laboratory Animal Welfare)により発行された動物福祉保証(Animal Welfare Assurance)を有し、アメリカ農務省(USDA)に登録し、人道的保護および実験動物の使用に関する適用可能な法規の順守に責任を有する施設内動物実験委員会(IACUC:Institutional Animal Care and Use Committee)を有する。
データは、ペプチドを1日3回の1時間静脈内注入として投与した、実施例3に記載したカニクイザルの研究による。ペプチドの血漿レベルおよび尿レベルを実施例3のように求めた。
研究では、体重28〜32グラムの64匹の非近交OF−1メスマウス(Charles River、フランス)、および大腸菌C175−94(血清型O8:K48:H4)、1型線毛を産生する臨床分離体を用いた。ペプチドは、NAB815(ロット1054308)およびポリミキシンB(シグマアルドリッチ、バッチBCBF8382V)であった。研究は、Statens Serum Institut(デンマーク、コペンハーゲン)が行った。
