Abstract:
Disclosed is a substituted 6-nitroquipazine of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are each selected from the group consisting of H, Fl, CL, Br, I, CF.sub.3, CH.sub.2 CH.sub.2 F, CH.sub.3, CH.sub.2 CH.sub.3, and --CH(CH.sub.3).sub.2, and wherein one of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 is other than H.Also disclosed is a method for measurement of serotonin uptake sites in a sample, in which a radioligand is incubated with a sample and then the radioactivity of the radioligand bound to the sample is determined, utilizing a radio labeled substituted 6-nitroquipazine as the radioligand. Also disclosed is a method of manufacture and method of use.
Abstract:
The present invention provides a method for treating a brain injury. This method comprises administering to a mammal afflicted with a brain injury a pharmaceutical composition therapeutically effective to increase glutamate receptor activity in the brain of said mammal. The pharmaceutical composition is to be administered after an acute postinjury phase of said affliction, a time when the level of NMDA receptor activity in the brain is below normal. The pharmaceutical composition may be administered subsequent to an initial treatment with an NMDA antagonist, the NMDA antagonist being administered during the acute postinjury phase of said affliction, a time when the level of NMDA receptor activity is above normal.
Abstract:
The present invention relates to pharmaceutical compositions for preventing or alleviating neurotoxicity. Said pharmaceutical compositions comprise as their active ingredient the stereospecific (+) enantiomers, having (3S,4S) configuration, of .DELTA..sup.6 -tetrahydrocannabinol (THC) type compounds of general formula (I), as defined hereinbelow. ##STR1##

Abstract:
Pharmaceutical compositions are described for preventing neurotoxicity, crising as active ingredient the stereospecific (+) enantiomer, having (3S,4S) configuration of .DELTA..sup.6 tetrahydrocannabinol type compounds. The compositions are particularly effective in alleviating and even preventing neurotoxicity due to acute injuries to the central nervous system, including mechanical trauma, compromised or reduced blood supply as may occur in cardiac arrest or stroke, or poisonings. They are also effective in the treatment of certain chronic degenerative diseases characterized by gradual neuronal loss.
Abstract:
The present invention provides certain novel 4-phenylpinene derivatives, and teaches how to use said novel derivatives and related compounds in pharmaceutical compositions that have utility in treating various pathological conditions associated with damage to the central nervous system. The active ingredient of the pharmaceutical compositions according to the present invention is a compound of the formula: ##STR1## wherein A - - - B designates an optional double bond, R.sub.1 designates a variety of organic moieties, G designates alkyl, halogen, or various oxy groups, and R.sub.3 designates various alkyl groups, ether groups, or combinations thereof.
Abstract:
A composition useful as an imaging agent comprises a beta adrenergic receptor antagonist compound, preferably iodopindolol, to which is covalently attached an iodine radioisotope such as .sup.123 I or .sup.124 I. This composition is used in a method for radioimaging beta adrenergic receptors in a tissue, preferably brain. In particular, the method is useful with the radioimaging technique of single photon emission computed tomography (SPECT) or positron emission tomography (PET). The above composition, as well as a kit comprising a set of one or more standard radiographic images of beta adrenergic receptors, are also useful in methods for (1) diagnosing an alteration in beta adrenergic receptors in a tissue, particularly brain; (2) diagnosing suicidal depression in a subject; and (3) detecting the therapeutic normalization of beta adrenergic receptor expression in a subject.
