Abstract:
Selected bis-amino acid hydroxyethylamino sulfonamide compounds of formula (I) are effective as retroviral protease inhibitors, and in particular as inhibitors of HIV protease. The present invention relates to such retroviral protease inhibitors and, more particularly, relates to selected novel compounds, composition and method for inhibiting retroviral proteases, such as human immunodeficiency virus (HIV) protease, prophylactically preventing retroviral infection or the spread of a retrovirus, and the treatment of a retroviral infection.
Abstract:
The present invention relates to crystalline forms of the compound ( S )-1-[( S )-2-(4-methoxybenzamido)-3-methylbutyryl]- N -[( S )-2-methyl-1-(trifluoroacetyl)propyl]pyrrolidine-2-carboxamide (I) and crystalline solvates thereof which are inhibitors of human leukocyte elastase (HLE), also known as human neutrophil elastase (HNE), making them useful whenever such inhibition is desired, such as for research tools in pharmacological, diagnostic and related studies and in the treatment of diseases in mammals in which HLE is implicated. The invention also includes phrmaceutical compositions containing the crystalline forms and solvates, processes for preparing the crystalline forms and solvates and intermediates useful in the synthesis of the crystalline forms and solvates.
Abstract:
Novel peptides having the activity of regulating the function of a cell membrane receptor which carries an intracellular carboxy-terminal amino acid sequence of -A1-A2-A3, carrying an amino acid sequence consisting of at least three amino acids in the lengthwise direction, and having a carboxy-terminal sequence of -X-Y-Z (wherein X is the same as A1 or represents an amino acid belonging to the same category as A1 does; Y represents an L-amino acid or glycine; and Z is the same as A3 or represents an amino acid belonging to the same category as A3 does); derivatives thereof improved in the biological stability, cell membrane permeability or the above-mentioned regulating activity of the same and pharmaceutically acceptable salts thereof; medicinal compositions containing these compounds; a method for analyzing the function of a receptor or the C-terminus thereof by using these compounds; a method for regulating the signal transmission by a cell membrane receptor; and a method for treating diseases in association with the signal transmission by cell membrane receptors.
Abstract:
The present invention is directed to novel tricyclic antidepressant derivatives which are synthesized for the covalent attachment to antigens (proteins or polypeptides) for the preparation of antibodies or receptors to tricyclic antidepressant and tricyclic antidepressant metabolites. The resulting novel antigens may be used for the production of antibodies or receptors using standard methods. Once generated, the antibodies or receptors and the novel derivatives which are covalently attached to proteins, polypeptides or labels my be used in the immunoassay process.
