The present invention relates to novel fluorescent dyes, novel fluorogenic and fluorescent reporter molecules and new enzyme assay processes that can be used to detect the activity of caspases and other enzymes involved in apoptosis in whole cells, cell lines and tissue samples derived from any living organism or organ. The reporter molecules and assay processes can be used in drug screening procedures to identify compounds which act as inhibitors or inducers of the caspase cascade in whole cells or tissues. The reagents and assays described herein are also useful for determining the chemosensitivity of human cancer cells to treatment with chemotherapeutic drugs. The present invention also relates to novel fluorogenic and fluorescent reporter molecules and new enzyme assay processes that can be used to detect the activity of type 2 methionine aminopeptidase, dipeptidyl peptidase IV, calpain, aminopeptidase, HIV protease, adenovirus protease, HSV-1 protease, HCMV protease and HCV protease.
本发明涉及新型荧光染料、新型荧光报告分子和新的酶测定方法,可以用于检测整个细胞、细胞系和来自任何生物体或器官的组织样本中参与凋亡的caspase和其他酶的活性。报告分子和测定方法可用于药物筛选程序,以识别在整个细胞或组织中作为caspase级联抑制剂或诱导剂的化合物。本文介绍的试剂和测定也可用于确定人类癌细胞对化疗药物治疗的化学敏感性。本发明还涉及新型荧光报告分子和新的酶测定方法,可用于检测第2型甲硫氨酸肽酶、二肽基肽酶IV、钙蛋白酶、氨肽酶、HIV蛋白酶、腺病毒蛋白酶、HSV-1蛋白酶、HCMV蛋白酶和HCV蛋白酶的活性。
