摘要:
The present invention relates generally to methods for determining the effectiveness of ongoing antidepressant therapy via analysis of the associated of Gsα with components of the plasma membrane or cytoskeleton of cells from peripheral tissues of the depressed individual as well as to methods involved in screening for effective antidepressant agents via their ability to cause a difference in the association of Gsα with components of the plasma membrane or cytoskeleton of cells.

The present invention provides a method for identifying an agent to be tested for an ability to treat a psychotic disorder in a patient in need of such treatment. The invention provides a method for screening candidate drugs for anti-psychotic drug activity, preferably atypical anti-psychotic activity, comprising contacting cells or tissues with a candidate drug, determining levels of phosphorylation of the intracellular signaling proteins, DARPP-32, ERK1, ERK2 and CREB, in said cells or tissues and determining the pattern of the levels of phosphorylation of the proteins. The pattern of the levels of phosphorylation of DARPP-32, ERK1, ERK2 and CREB is, in certain embodiments, compared with the pattern of the levels of phosphorylation of DARPP-32, ERK1, ERK2 and CREB in the presence of an atypical anti-psychotic drug.

Immunoassay methods and reagents for the specific quantification of imipramine or desipramine in a test sample are disclosed. The measurement of imipramine or desipramine is accomplished in a specific immunoassay employing antibodies prepared with imipramine or desipramine derivatives of formula (III), wherein P is an immunogenic carrier material, X is two heteroatoms, Y is a linking group comprising from 1 to 6 carbon atoms and P is an immunogenic carrier material, and wherein for imipramine, R is CH3, and for desipramine, R is H. The present invention also describes the synthesis of unique labeled reagents of the structure of formula (IV), wherein Z is a linking group comprising 1 to 4 carbon atoms and 0 to 2 heteroatoms and Q is a detectable moiety, preferably fluorescein or a fluorescein derivative, and wherein for imipramine, R1 is CH3, and for desipramine, R1 is H.
摘要:
Method and reagents for determining a compound of interest present in a test sample also containing one or more interfering compounds having substantially similar chemical structures, and otherwise analytically indistinguishable from each other, employing a pretreatment reagent capable of selectively modifying the chemical structure of one of the compounds without significantly modifying or altering the chemical structure of the other one of the compounds. The selective modification results in the modified compound having a chemical structure which is substantially dissimilar to the chemical structure of the other one of said compounds wherein the compounds are substantially distinguishable from each other to permit the analytical determination of one or the other of such compounds by immunoassay, high pressure liquid chromatography, and thin layer chromatography techniques, especially for the fluorescent polarization immunoassay determination of tricyclic antidepressant drugs in the presence of phenothiazines.

Reagents, compounds useful for producing the reagents and fluorescence polarization immunoassay utilizing the reagents, for determining tricyclic antidepressants in biological fluids, are disclosed.
摘要:
Serum is passed through a column containing alkylated silica gel. The column is then washed with a mixture comprising from about 50 to 85 volume percent of an aqueous buffered medium of pH from about 3.5 to 5.0 and from about 15 to 50 volume percent of an organic solvent containing from 1 to 6 carbon atoms and from 1 to 5 heteroatoms selected from oxygen, nitrogen, and sulfur. The tricyclic antidepressant drug is removed from the column with an eluent mixture comprising from about 0 to 75 volume percent of an aqueous buffered medium of pH of about from 6 to 8 and from about 25 to 100 volume percent of one or more organic solvents containing from 1 to 6 carbon atoms and from 1 to 5 heteroatoms selected from oxygen, nitrogen, and sulfur. In this way, a tricyclic antidepressant drug sample, free from interfering metabolites, for use in assay determinations is obtained.
