摘要:
The present invention is directed to gambogic acid, analogs and derivatives thereof, represented by general Formulae (I-III) wherein R1-R5 are defined herein. The present invention also relates to the discovery that compounds having Formulae (I-III) are activators of caspases and inducers of apoptosis. Therefore, the activators of caspases and inducers of apoptosis of this invention can be used to induce cell death in a variety of clinical conditions in which uncontrolled cell growth and spread of abnormal cells occurs.
摘要:
The use of caspase inhibitors for treating cell death induced by radionuclides, biological agents, or chemical agents is disclosed. In particular, treatment of diseases or conditions caused by exposure to radionuclides, biological agents, or chemical agents, spread of radionuclides, biological agents, or chemical agents, explosion of radionuclides, biological agents, or chemical agents by terrorists or accidental exposure to radionuclides, biological agents, or chemical agents from a nuclear power plant, manufacturing or processing plant, research facility, or hospital is disclosed.
摘要:
The present invention is directed to optionally substituted 4-substituted-1-(arylmethylidene)thiosemicarbazide, 4-substituted-1-(arylcarbonyl)thiosemicarbazide and analogs thereof, represented by the Formulae (I) and (II), wherein A1, A2, Q and R1-R3 are defined herein. The present invention also relates to the discovery that compounds having Formulae (I) and (II) are activators o f caspases and inducers of apoptosis. Therefore, the activators of caspases and inducers of apoptosis of this invention may be used to induce cell death in a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.
摘要:
The present invention is directed to substituted 4H-chromene and analogs thereof, represented by general Formula (I), wherein A, B, X, Y, Z and R5 are defined herein. The present invention also relates to the discovery that compounds having Formula (I) are activators of caspases and inducers of apoptosis. Therefore, the activators of caspases and inducers of apoptosis of this invention can be used to induce cell death in a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.
摘要:
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.
