Abstract:
A method for synthesizing an 18 F-labeled probe. The method includes a step of eluting an amount of 18 F with a first solvent which includes a predetermined amount of water and at least one organic solvent. In this step, the 18 F elutes as an 18 F solution. The method also includes a step of using the 18 F solution to perform 18 F-labeling in the presence of at least one labeling reagent and at least one phase transfer catalyst so as to generate the 18 F-labeled probe. In the method, there is no step of drying the 18 F starting from a time when the eluting step is performed and ending at a time when the 18 F-labeling step is performed.
Abstract:
Imaging agents of formula (I) and methods for detecting neurological disorders comprising administering ti a patient in need compounds of formula (I) capable of binding to tau proteins and β-amyloid peptides are presented herein. The invention also relates to methods of imaging Aβ and tau aggregates comprising introducing a detectable quantity of pharmaceutical formulation comprising a radiolabeled compound of formula (I) and detecting the labeled compound associated with amyloid deposits and/or tau proteins in a patient. These methods and compositions enable preclinical diagnosis and monitoring progression of AD and other neurological disoders.
Abstract:
Methods and apparatus to assess current aspects of Quality Control useful for release of radioactive compounds for imaging, such as PET tracers as injectables, in an automated manner, without user interference, and in compliance with regulatory guidelines. The present method and system relates to an integrated automated quality control analysis of a substance utilizing a single sample injection for a plurality of inline quality control tests. A quantitative analysis of the sample via the plurality of quality control tests is conducted. A measurement value of each of the plurality of quality control parameters is determined and a comparison of each measurement value of the plurality of quality control parameters with a predetermined corresponding criterion value is made. A cumulative quality rating for the sample is determined and the validated sample is released based on the quality rating.
Abstract:
Methods and apparatus for facilitating the synthesis of compounds in a nonflow-through device are presented. Application of the nonflow-through methods and microfluidic devices to the synthesis of radiolabeled compounds is described. These methods and apparatus enable the introduction of a pressurized gas through a tangential slit into a vortex reactor of the nonflow-through device, while one or more liquids are delivered to the reaction chamber through the same or different inlet ports. The introduction of the pressurized gas produces a cyclonic motion of the mixture within the reactor. Such a mechanism may be used to facilitate the evaporation of various liquids within the reactor at lower temperatures, thus reducing the production of unwanted byproducts that are associated with the use of high temperatures. In addition, thorough mixing of various liquids may be effected rapidly while allowing chemical reactions to take place efficiently within the vortex reactor.
Abstract:
Disclosed here in are compounds and methods of diagnosing Alzheimer's Disease or a predisposition thereto in a mammal, the method comprising administering to the mammal a diagnostically effective amount of a radiolabeled compound, wherein the compound is selected from the group consisting of radiolabeled flavones, coumarins, carbazoles, quinolinones, chromenones, imidazoles and triazoles derivatives, allowing the compound to distribute into the brain tissue, and imaging the brain tissue, wherein an increase in binding of the compound to the brain tissue compared to a normal control level of binding indicates that the mammal is suffering from or is at risk of developing Alzheimer's Disease
