Rは、(C1−C3アルキル又はフルオロアルキルで)任意に置換されたC4−C10基であり、n=1である場合、Rは、C5−C10アルキル基(好ましくは、非置換直鎖アルキル基)であり、n=2である場合、Rは、(C1−C3アルキル又はフルオロアルキルで)任意に置換されたC4−C10アルキル基、好ましくは非置換直鎖アルキル基である。あるいは、次の化学構造に従う化合物に関する。
「患者」という用語は、本発明の化合物を用いて予防的処置を含む処置が施される動物、好ましくはヒトを説明するために本明細書全体を通して使用される。ヒト患者のような特定動物に特異的な兆候、状態又は疾患状況の処置に関しては、患者という用語はその特定の動物のことを指す。本発明のほとんどの場合、患者とは、ざ瘡、ある程度の禿頭症(完全な禿頭症を含む)又は多毛症を患うヒトのことである。
生物学的活性に関する試験の一部として、エステル(好ましくはエチルエステル)及び親カルボン酸を、アンドロゲン受容体(AR)との結合、及びアンドロゲン受容体/アンドロゲン受容体エステラーゼ(AR/ARE)のトランスフェクト細胞(以下に記載)におけるインビトロの抗アンドロゲン活性について試験する。良好な局所用抗アンドロゲン剤として、エステルは、高いAR親和性と高い抗アンドロゲン活性を示さなければならないが、親カルボン酸は、これらの特性が非常に弱いか、又はこれらの特性を欠くべきである。この試験の長所の1つは、エステルのアルコール部分を変更することによって加水分解速度を変更できることであり、従って類似体が、予想するよりも大きな全身性作用を有するようであれば、加水分解速度を大きくすることができ、逆もまた同様である。例えば、良好な受容体結合及び抗アンドロゲン活性を示すエステルに関し、そのカルボン酸は活性を欠くので、エステラーゼ加水分解を増大又は減少させるように設計して、エステル基のアルコール部分の構造を変更して、一連のエステルが合成される(例えば、加水分解を増大させるためのプロピル、フルオロエチルエステル、並びに加水分解を減少させるためのイソプロピル及びネオペンチルエステルなどの立体障害エステル又は親油性を減少させるメチル)。これらのエステルは、肝臓エステラーゼ試験(下記)で、それらの加水分解速度について試験される。これらの追加エステルについて、AR/AREのトランスフェクト細胞でAR結合及び抗アンドロゲン活性を試験する。結合試験は、0〜2℃で行なわれるので、エステラーゼ加水分解は重要な因子ではない。しかし、トランスフェクト細胞試験では、酵素加水分解が生じ、エステル基の加水分解速度が生物学的活性に影響を与える。故に、受容体結合について補正した後では、生物学的活性と酵素加水分解との間には相関がある。例えば、同様の受容体結合を示す化合物は、加水分解速度(エステル構造)と相関する生物学的活性が異なる。この相関により、インビボ試験が選択可能となり、「局所」作用のために加水分解速度(エステル構造)の最適化が可能になる。エステル構造は、局所作用を最大限にするために加水分解速度を低下させ、又は全身性作用を最小限にするために加水分解速度を増大させるように変更できる。それに続くインビボ試験において、その目的は、良好な局所的抗アンドロゲン活性を示し、全身性作用がある場合は最小限にする化合物を見出すことである。こうした試験の結果から、インビボ試験に関してそれぞれのファミリーにおいて初期の選択肢を同定する。この初期試験の結果は、必要とされる方向性(加水分解を増大又は減少させる)を示し、最終的な病型について適切なエステルを導く。
インビトロ生物学的試験。上述したエステル類似体をまず、AR親和性を測定することによる抗アンドロゲン(及びアンドロゲン)活性及び培養液中の細胞におけるアンドロゲン応答性レポーター遺伝子のアンドロゲン刺激に拮抗する効力について選別する。さらに、これらの類似体がエステラーゼによって加水分解される速度を測定する。一部の先駆物質(スピロノラクトン及びミフェプリストン)の活性スペクトルのために、他のステロイド受容体系(糖質コルチコイド及び鉱質コルチコイド)との潜在的な交差反応を測定する。これは、レポーター遺伝子構造体でトランスフェクトされた細胞において、鉱質コルチコイド及び糖質コルチコイド受容体との結合、並びに受容体作用の阻害を計測することによって行なう。
