摘要:
Compounds and methods for stimulating neurogenesis (e.g., post-natal neurogenesis, including post-natal hippocampal and hypothalamic neurogenesis) and/or protecting neuronal cell from cell death are disclosed herein. In vivo activity tests suggest that these compounds may have therapeutic benefits in neuropsychiatric and/or neurodegenerative diseases such as schizophrenia, major depression, bipolar disorder, normal aging, epilepsy, traumatic brain injury, post-traumatic stress disorder, Parkinson's disease, Alzheimer's disease, Down syndrome, spinocerebellar ataxia, amyotrophic lateral sclerosis, Huntington's disease, stroke, radiation therapy, chronic stress, abuse of a neuro-active drug, retinal degeneration, spinal cord injury, peripheral nerve injury, physiological weight loss associated with various conditions, as well as cognitive decline associated with normal aging, chemotherapy, and the like.

摘要:
An improved method for preparing opipramol (I) is disclosed, wherein iminostilbene (II) is reacted with 1-bromo-3-chloropropane in the presence of a weak base selected from a hydrogen phosphate salt and an acetate salt and in the presence of a phase transfer agent to produce N-(3-halopropyl)iminostilbene (III), which is mixture of N-(3-chloropropyl)iminostilbene and N-(3-bromopropyl)iminostilbene, and then N-(3-halopropyl)iminostilbene is reacted with N-(2-hydroxyethyl)piperazine to form opipramol, as shown in the following equations, where X is chlorine or bromine. ##STR1##
摘要:
This disclosure relates to a method and reagents for determining ligands in biological fluids such as serum, plasma, spinal fluid, amnionic fluid and urine. In particular, this disclosure relates to a fluorescence polarization immunoassay procedure and to a novel class of tracer compounds employed as reagents in such procedures. The procedure disclosed combines the specificity of an immunoassay with the speed and convenience of fluorescence polarization techniques to provide a means for determining the amount of the specific ligand present in a sample.
摘要:
This invention relates to tricyclic compounds bearing on the nitrogen atom of the medium ring an 3-amino 2-hydroxy propylamino carbonyl side chain and their physiologically compatible acid addition salts. This invention also relates to a process for making the same which includes the steps of condensing a tricyclic carbamic acid or one of its functional derivative with a 1,3-diamino 2-hydroxy propane derivative. The compounds of the invention have therapeutical utility namely in the cardiovascular field as antiarrythmic agents.
