A method is disclosed for analyzing a biological sample by antibody profiling for identifying forensic samples or for detecting the presence of an analyte. In an illustrative embodiment of the invention, the analyte is a drug, such as marijuana, cocaine, methamphetamine, methyltestosterone, or mesterolone. The method involves attaching antigens to the surface of a solid support in a preselected pattern to form an array wherein the locations of the antigens are known; contacting the array with the biological sample such that a portion of antibodies in the sample reacts with and binds to antigens in the array, thereby forming immune complexes; washing away antibodies that do form immune complexes; and detecting the immune complexes, thereby forming an antibody profile. Forensic samples are identified by comparing a sample from an unknown source with a sample from a known source. Further, an assay, such as a test for illegal drug use, can be coupled to a test for identity such that the results of the assay can be positively correlated to the subject's identity.

The invention relates generally to ephedrine or pseudoephedrine compositions containing biocompatible organoleptic (food flavoring) excipients that would prevent the illicit manufacture of methamphetamine from ephedrine or pseudoephedrine.

The present invention also provides a method of treatment of cocaine, morphine, heroin, nicotine, amphetamine, methamphetamine, or ethanol addiction by treating a mammal with an effective amount of gamma vinylGABA or a pharmaceutically acceptable salt thereof.

A method for analyzing a biological sample by antibody profiling for identifying forensic samples or for detecting the presence of an analyte. In an embodiment of the invention, the analyte is a drug, such as marijuana, Cocaine (crystalline tropane alkaloid), methamphetamine, methyltestosterone, or mesterolone. The method comprises attaching antigens to a surface of a solid support in a preselected pattern to form an array wherein locations of the antigens are known; contacting the array with the biological sample such that a portion of antibodies in the sample reacts with and binds to the antigens in the array to form immune complexes; washing away antibodies that do form immune complexes; and detecting the immune complexes, to form an antibody profile. Forensic samples are identified by comparing a sample from an unknown source with a sample from a known source. Further, an assay, such as a test for illegal drug use, can be coupled to a test for identity such that the results of the assay can be positively correlated to the subject's identity.

Compounds of methamphetamine derivatives having a meta-substituted alkyl linker on the benzene ring and a protective group on the nitrogen of the methamphetamine hapten. Such compounds have the structurewherein R1 is an alkyl linker comprising 2-15 carbon atoms and 0-6 heteroatoms, R2 is a leaving group, and R3 is a protecting group.

The invention discloses preparation and an application of a fluorescent compound having a sensing function on methamphetamine and methamphetamine analogues and preparation and an application of a fluorescent sensing thin film, and belongs to the technical field of fluorescent compound preparation. The fluorescent compound contains a cholesterol fragment and a 3,4,9,10-perylenetetracarboxylic acid anhydride unit, the cholesterol fragment has the advantages of rigid skeleton, multiple chiral centers and strong van der Waals effect and the like, 3,4,9,10-perylenetetracarboxylic acid anhydride has high fluorescence quantum yield, good photochemistry stability and strong pi-pi stacking interaction, and the construction units make the prepared fluorescent compound have supramolecular characteristics and extremely rich assembly behaviors simultaneously. The prepared sensing thin film has the advantages of controllable micro-morphology, good stability and high sensitivity, and can be used repeatedly; through device formation and combining development with a dedicated fluorescence detection platform, the sensing thin film is expected to be used for a dedicated detector for super sensitive gas-phase detection of methamphetamine and the methamphetamine analogues, and provides a technical support for drug investigation detective works.

The present invention provides synthetic immunochemical haptens for the generation of antibodies that are designed to recognize the common molecular features of d-methamphetamine-like abused stimulants with insignificant cross-reactivity to endogenous substrates (e.g. dopamine) or over-the-counter medications (e.g. 1-methamphetamine, pseudoephedrine, phenylpropanolamine and ephedrine). These monoclonal antibodies and their antigen binding fragments are useful in treatment plans for recovering addicts, in emergency room settings for rapidly reversing a drug overdose, in protection of fetuses from drug-abusing pregnant mothers or in a psychiatric setting to reduce the exacerbation of psychotic disorders caused by stimulant drugs.

The invention belongs to the technical field of drug detection, and particularly relates to a method for detecting methamphetamine through surface enhanced Raman spectroscopy, which includes the following steps: step I, pretreating a to-be-detected sample, so as to form sample solution; step II, preparing gold sol or silver sol; step III, uniformly mixing the test sample solution obtained through the step I and the gold sol or the silver sol obtained through the step II, so as to form the to-be-detected sample that is on standing; step IV, enabling the mixed to-be-detected sample obtained through the step III to be dripped on a slide and naturally evaporated for Raman spectrometry, thereby obtaining the SERS spectrogram of the gold sol and the to-be-detected sample or the SERS spectrogram of the silver sol and the to-be-detected sample; and step V, comparing the SERS spectrogram of the to-be-detected sample with the standard SERS spectrogram of the methamphetamine, so as to determine whether the sample contains the methamphetamine. The method for detecting the methamphetamine is simple to operate and quick to detect, has low sample consumption and detection cost, and can be widely applied to the detection field of the drug.

Cyclic tetrapeptides that are kappa opioid receptor (KOR) antagonists can be used in therapeutic applications for treating, inhibiting, and / or preventing drug addiction, drug use, or drug seeking behavior in a subject. This can include subjects that have a history of drug addiction. The drug can be selected from cocaine, alcohol, amphetamines, methamphetamines, nicotine, opiate, or combinations thereof. These cyclic tetrapeptides can also be useful for treating, inhibiting, and / or preventing stress-induced drug seeking behavior.

The invention generally relates to monoclonal antibodies that recognize at least one compound from the group consisting of (+) methamphetamine, (+) amphetamine, and (+) 3,4-methylenedioxymethamphetamine ((+) MDMA). Generally speaking, the monoclonal antibodies do not recognize (−) methamphetamine, (−) amphetamine, or (−) MDMA.
