An activity-based probe, containing an irreversibly locked GFP-like fluorophore, was synthesized and evaluated as an inhibitor of human cathepsins and, as exemplified with cathepsin K, it proved to be suitable for ex vivo imaging and quantification of cysteine cathepsins by SDS-PAGE.
合成了一种基于活性探针的不可逆锁定GFP样荧光团,并评估其作为人类半胱
氨酸酶的
抑制剂。以半胱
氨酸酶K为例,该探针被证明适用于通过
SDS-PAGE进行体外成像和定量分析半胱
氨酸酶。
