Abstract
【選択図】なし
Description
ヒト前骨髄性白血病細胞(HL−60細胞)は、インビトロで培養され、細胞生存性は、処理後に細胞数を定量することによって測定された。HL−60細胞は、DCP、カルボプラチン、エトポシド、及びメトトレキサート(MTX)の一連の段階的濃度で処理された。試験薬剤と対照薬剤のOD490値の比較後、細胞増殖の相対抑制率の指数が得られた。IC50値は、SPSS16.0ソフトウェアを使用することによって計算された。DCP、カルボプラチン、エトポシド、及びMTXのIC50値は、それぞれ18.558μM、17.321μM、15.342μM、及び15.285μMであった。結果は、図1に示される。
腎臓がん細胞株A498細胞は、インビトロで培養され、細胞生存性は、処理後に細胞数を定量することによって測定された。A498細胞は、DCP、カルボプラチン、及びフルオロウラシル(5−FU)の一連の段階的濃度で処理された。試験薬剤と対照薬剤のOD490値の比較後、細胞増殖の相対抑制率の指数が得られた。IC50値は、SPSS16.0ソフトウェアを使用することによって計算された。DCP、カルボプラチン、及び5−FUのIC50値は、それぞれ20.887μM、18.357μM、及び18.164μMであった。結果は、図5に示される。
以下のケースは、脳及び副腎における複数転移を有するメラノーマ患者のDCPの医薬的使用を要約する。転移性腫瘍は、まずMRIによって患者の脳の右前頭葉及び頭頂葉で検出され、1ヶ月後に手術によって除去された。しかしながら、周囲に浮腫を有する新しい腫瘤が頭頂葉の左側に検出された。新しい腫瘍が検出された後、2ヶ月で腫瘍が大きく成長し、腫瘍のまわりの浮腫は、悪化した。患者は、約3週間、DCP溶液(3日ごとに1回で250mL水溶液中の150mgのDCP)で処理された。MRIは、腫瘍の収縮を示し、腫瘍のまわりの浮腫が緩和された。
本発明の水性又は固体医薬組成物は、少なくとも一種の追加の治療薬又はアジュバントの適切な量がありで又はなしで、DCPの有効量を含む。DCP、並びに治療薬又はアジュバントは、医薬的に許容可能な担体又は水性媒体に溶解又は分散されることができる。
