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.
摘要:
Novel 4-substituted piperidine analogs, pharmaceutical compositions containing the same and the method of using 4-substituted piperidine analogs as selectively active antagonists of N-methyl-D-aspartate (NMDA) receptor subtypes for treating conditions such as stroke, cerebral ischemia, central nervous system trauma, hypoglycemia, anxiety, convulsions, aminoglycoside antibiotics-induced hearing loss, migraine headaches, glaucoma, CMV retinitis, chronic pain, opioid tolerance or withdrawals, or neurodegenerative disorders, such as lathyrism, Alzheimer's Disease, Parkinsonism and Huntington's Disease are described. Also described are novel methods for preparing 4-substituted piperidine analogs and novel intermediates of the 4-substituted piperidine analogs.
摘要:
Tri- and tetra-substituted guanidines which exhibit a high binding affinity to phencyclidine (PCP) receptors and, more preferably, low affinity to the brain sigma receptors. These guanidine derivatives act as non-competitive inhibitors of glutamate induced responses of the NMDA receptor by acting as blockers for the ion channel of the NMDA receptor-ion channel complex. These compounds thus exert neuroprotective activity and are useful in the therapeutic treatment of neuronal loss in hypoxia, hypoglycemia, brain or spinal cord ischemia, and brain or spinal chord trauma as well as being useful for the treatment of epilepsy, Alzheimer's disease, Amyotrophic Lateral Sclerosis, Parkinson's disease, Huntington's disease, Down's Syndrome, Korsakoff's disease and other neurodegenerative disorders.

The invention relates to 5-(iminomethano)-10,11-dihydro-5H-dibenzo�a,d!cycloheptene and derivatives thereof. The invention also relates to the use of such compounds for the treatment or prevention of neuronal loss in ischemia, hypoxia, brain or spinal chord trauma, as well as for the treatment of Alzheimer's disease, amyotrophic lateral sclerosis, Huntington's disease and Down's syndrome.

摘要:
Methods of treating or preventing neuronal loss associated with stroke, ischemia, CNS trauma, hypoglycemia and surgery, as well as treating neurodegenerative diseases including Alzheimer's disease, amyotrophic lateral sclerosis, Huntington's disease and Down's syndrome, treating or preventing the adverse consequences of the hyperactivity of the excitatory amino acids, as well as treating anxiety, chronic pain, convulsions, inducing anesthesia and treating psychosis are disclosed by administering to an animal in need of such treatment a compound having high affinity for the glycine binding site, lacking PCP side effects and which crosses the blood brain barrier of the animal.Also disclosed are novel 1,4-dihydroquinoxaline-2,3-diones, and pharmaceutical compositions thereof. Also disclosed are highly soluble ammonium salts of 1,4-dihydroquinoxaline-2,3-diones.
摘要:
Disclosed is a method of treating or preventing neuronal loss associated with stroke, ischemia, CNS trauma or hypoglycemia. The method comprises administering to an animal a compound of the formula: ##STR1## or a pharmaceutically acceptable salt thereof; wherein n is zero or 1; R.sup.4, R.sup.5, R.sup.6 are independently hydrogen, nitro, amino, halo, haloalkyl, cyano, alkyl, cycloalkyl, alkenyl, alkynyl, azido, acylamino, alkylsulfonyl, aryl, substituted aryl, heteroaryl, alkoxy, trialkylsilyl-substituted alkoxy, aryloxy, substituted aryloxy, heteroaryloxy, a heterocyclic group, a heterocyclicoxy group, aralkoxy, or haloalkoxy; and R.sup.c and R.sup.d are defined in the specification. These compounds have high binding to the glycine site of the NMDA receptor.
