ロイシン及びグルタミン酸由来のアシル残基を化合物(1)(RhoHM)の一方のアミノ基に結合させた化合物(2)(Leu−RhoHM)及び化合物(3)(γGlu-RhoHM)を中性リン酸バッファーに溶解して、プロテアーゼ (ロイシンアミノペプチダーゼ(LAP, porcine kidney, SIGMA L5006-25UN)及びγ-グルタミルトランスペプチダーゼ(GGT, equine kidney, SIGMA G9270-100UN)を作用させた。各化合物の5 μM ジメチルスルホキシド(DMSO)溶液 3 μLを3 mL の0.1 M リン酸ナトリウムバッファー(pH 7.4) に最終濃度 5 μMとなるように溶解し、それぞれLAP (0.15 U)及びGGT (1.1 U) を加えて37℃で酵素反応を行った。励起波長は501 nmとした。この結果、両者ともプロテアーゼによるアシル基の加水分解により開環体を与え、その結果、即時に吸収及び蛍光強度の顕著な上昇が認められた(図1)。
化合物(2)及び(3)を用いて酵素特異性を検討した。DMSO溶液 (5 mM) のうち3 μLを3 mL の0.1 M リン酸ナトリウムバッファー(pH 7.4) に最終濃度 5 μMとなるように溶解し、LAP(0.4 U)を加えて 37℃で酵素反応を行った。この結果、化合物(2)(Leu-RhoHM)とLAPとの反応により顕著な蛍光強度の増強が認められたが、化合物(3)(γGlu-RhoHM)とLAPとを反応させた場合には蛍光強度の増強が認められなかった(図2)。一方、化合物(3)はGGTと反応して顕著な蛍光強度を与えたことから(例2)、γGlu-RhoHMはGGTを特異的に検出するものと考えられる。
