インビボ薬理学的テスト
CIPNに対する式(I)の化合物の神経保護作用を検出する目的で、本発明者らは、ビンクリスチン、パクリタキセル及びオキサリプラチンの3種の異なる全身的な投薬計画を用いて、この病状の異なるラットモデルで実験した。比較のために、CIPNの処置において臨床的に用いられる化合物である、痛覚過敏改善薬物ガバペンチンを同一の投薬計画でテストした。
これらの結果は図1にまとめられている。ビンクリスチン処置は、処置したラットの機械的な足圧閾値の低減から明らかであるとおり、顕著、かつ、遷延性の機械的痛覚過敏をもたらした。ビンクリスチン機械的感覚過敏の明白で顕著な回復が、化合物の処置から30及び60分後に経口的に与えた100mg/kgの実施例3の化合物(NiK−13317)により誘導された(図1)。興味深いことに、同じ投与量で与えたガバペンチンは、如何なる顕著な作用も有していなかった。NiK−13317及びガバペンチンは、媒体で処置した動物に対しては如何なる顕著な作用も有していなかった。
ビンクリスチンのように、タキソール処置もまた、顕著な機械的痛覚過敏をもたらした。このモデルにおいて、NiK−13317(100mg/kg経口投与した)は、処置から30及び60分後にラット足圧閾値を著しく高めた。反対に、参照標準ガバペンチンは、同じ実験条件において、いかなる痛覚過敏改善作用も引き起こすことができなかった(図3A)。この効力の欠如は、ビンクリスチン痛覚過敏モデルを用いて得た前のデータと一致していた。NiK−13317はまた、投与から30〜90分後に、腹腔内(30mg/kg)及び静脈内(3mg/kg)の後でも活性である。腹腔内又は静脈内投与したガバペンチンは、如何なる顕著な作用も有していなかった(それぞれ図3B及びC)。
オキサリプラチンの反復投与は、処置の第1週目から明らかである足圧閾値の低減を生じさせた(図4)。最大痛覚過敏を、処置の2週間後に得た。NiK−13317及びガバペンチンを、オキサリプラチン処置の3日間前から1日1回、経口(100mg/kg)で反復的に投与した。化合物投与は、化学療法注射と同じ日に実施した。ラットを、毎週、NiK−13317投与の30分後、及びオキサリプラチン注射の前に機械的痛覚過敏についてテストした。
タキソール、オキサリプラチン及びビンクリスチンでのインビトロ併用研究
CIPNの処置のためのNiK−13317の使用が抗癌処置の効力に影響しないであろうことを検証するために、公知の抗癌薬の細胞傷害性に対するNiK−13317の作用を、HT29ヒト大腸癌腫株細胞を用いてインビトロで試験した。
