Abstract
Description
本出願は、本願の開示として参照により援用される2003年4月30日出願の仮出願No.60/466982の、アメリカ特許法119条(e)に基づく利益を主張する。
本発明は有機化学、医化学、生化学、生物学及び医学に関する。特に、カルバセフェムβ−ラクタム系抗生物質、医学的に許容できるその塩、及び細菌感染、とりわけ従来のβ−ラクタム系に耐性のある細菌を原因とする感染の治療のための当該化合物及びその塩の使用に関する。
nが0の場合、A1は酸素及び硫黄からなる群から選択され、R2は存在せず、A2,A3及びA5は炭素及び窒素からなる群から選択されて芳香族の5員環となり、R3は水素、−NH2及び−CH2S(CH2)2NH2からなる群から選択され、
nが1の場合、A1は炭素であり、A2,A3,A4及びA5の少なくとも1つは窒素、残りは炭素であり、R2は−CH2S(CH2)2NH2であり、A2が炭素の場合、R3は水素であり、A2が窒素の場合、R3は存在しない。
また、R1は水素、−CH3、−CH2CH3、−CH2F、及び−CH2CH2Fからなる群から選択される。
表1は、本発明の代表的な化合物のMIC及び血清結合値を示すものである。
“方法”という語句は、課題を解決するための手法、手段、技法及び手順であり、化学、薬学、生物学、生化学及び医学分野の当業者にとって公知な手法、手段、技法及び手順、またはこれらから容易に成し得る手法、手段、技法及び手順を含むものであるが、それらに限定されるものではない。
本発明は、細菌感染、特に従来のβ−ラクタム抗生物質に対する耐性を獲得した細菌による感染の治療に効果的な化合物、方法及び組成物を提供するものである。
ここに挙げる合成は例示にすぎず、どのような意味においても本発明の範囲を限定することを意図したものではなく、またそのように解釈されるものでもない。例えば、個々に挙げる化合物の合成には、非常に多くの方法があり、それらすべての方法は本発明の範囲内である。
本発明の化合物の送達経路としては、限定するものではないが、経口、直腸、経粘膜、筋内、皮下、髄内、鞘内、脳室内、静脈、硝子体内、腹膜内、鼻腔内、耳内、または眼内が挙げられる。経口及び経腸管が好ましい送達系路である。
本発明の化合物または薬学的に許容されるその塩は、そのまま、または1以上の賦形剤を有する医薬組成物として患者に投与することができる。種々の投与法に用いるための薬剤の処方技術については、Remington's Pharmacological Sciences, Mack Publishing Co., Easton, PAの最新版に記載されている。Remingtonに記載される処方及び技術は、主にヒトの患者に対する使用に関連するものであるが、畜産学及び農学分野の当業者にとって周知の技術を用いればヒト以外の患者に対する使用にも、容易に変更することができるであろう。
治療上または予防上有効な量を実現する適切な用量は、感染の激しさや進行程度、薬歴、患者の全体的な健康状態、薬物への応答などによって決まるが、これらすべては医師の知識、専門技術及び判断の範疇である。
本願で提示されるどの化合物であっても、当然ながら生物活性のスペクトルが調査される。最も好ましい実施例において、本発明の化合物は、従来のβ−ラクタム系抗生物質であるメチシリンやアンピシリンなどに耐性のある感染症において、バンコマイシンまたはセフォタキシムよりも優れた活性を示す。限定するものではないが、以下の手法を本発明の化合物の評価に用いても良い。
以上の詳細な説明では、本発明を説明する特定の実施例が記載されるが、当業者であれば本発明がその他の種々の方法により実施されることを認めるであろう。例えば、本発明の化合物は、数多くの異なる経路により合成しても良い。そうしたバリエーションもまた本発明の範囲内である。
