Cl2P(V)TMPP、MeO2P(V)TMPP及びEG2P(V)TMPPの吸収スペクトルを、分光光度計(島津製作所,UV−1650PC)を用いて測定した。測定には、10mMリン酸緩衝液(pH7.6)を使用した。
Cl2P(V)TMPP、MeO2P(V)TMPP及びEG2P(V)TMPPについて、蛍光極大波長、蛍光量子収率を測定した。測定は、分光蛍光光度計(株式会社日立ハイテクフィールディング製,F−4500)を用い、10mMリン酸緩衝液(pH7.6)中で行った。
Cl2P(V)TMPP、MeO2P(V)TMPP及びEG2P(V)TMPPについて、蛍光寿命τfを測定した。測定は、蛍光寿命測定装置(株式会社堀場製作所製、TemPro)を用い、10mMリン酸緩衝液(pH7.6)中で行った。
Cl2P(V)TMPP、MeO2P(V)TMPP及びEG2P(V)TMPPの一重項酸素生成量子収率を、以下の方法により算出した。すなわち、近赤外発光分光測定装置(浜松ホトニクス株式会社製,NIR−PIIシステム)により、蒸留水中における一重項酸素の発光強度を測定した。測定された発光強度の、メチレンブルーによる一重項酸素の発光強度(蒸留水中での一重項酸素生成量子収率0.52)に対する相対的な比率を一重項酸素生成量子収率とした。なお、発光強度の測定には、10mMリン酸緩衝液(pH7.6)を使用した。
Cl2P(V)TMPP、MeO2P(V)TMPP及びEG2P(V)TMPPの25℃の蒸留水に対する溶解度を測定した。
Cl2P(V)TMPP、MeO2P(V)TMPP及びEG2P(V)TMPPの光損傷作用を以下の方法により評価した。
5μMのCl2P(V)TMPPと10μMのヒト血清アルブミン(水溶性タンパク質、HSA)をそれぞれ含む1.2mLの10mMリン酸緩衝液(pH7.6)を、Cl2P(V)TMPPの評価用溶液1として調製した。同様にして、MeO2P(V)TMPP及びEG2P(V)TMPPそれぞれについて、評価用溶液1を調製した。
下記式により、タンパク質損傷の量子収率ΦDを算出した。
ΦD=(HSAの損傷速度)/(リンポルフィリン化合物が単位時間当たりに吸収する光子数)
HSAの損傷速度は、図2のグラフの近似直線の傾きから計算した。Cl2P(V)TMPP、MeO2P(V)TMPP及びEG2P(V)TMPPが単位時間当たりに吸収する光子数は、各化合物の吸収スペクトルと赤色発光ダイオード光源の発光スペクトルの重なりから計算した。
評価用液1を用いて、ヒト血清アルブミン(10μM)含有時のCl2P(V)TMPP、MeO2P(V)TMPP及びEG2P(V)TMPPの蛍光寿命τf *(短寿命成分τf1 *、長寿命成分τf2 *)を測定した。その結果と、それぞれの化合物単独の蛍光寿命τfに基づいて、下記式を用いて電子移動速度定数ketを算出した。
