An indole-based in vivo imaging agent is provided by the present invention that binds with high affinity to PBR, has good uptake into the brain following administration, and which has good selective binding to PBR. The invention also includes a precursor compound useful in the synthesis of the in vivo imaging agent of the invention, as well as a method for synthesis of said in vivo imaging agent comprising use of said precursor compound, and a kit for carrying out said method. Also provided is a cassette for automated synthesis of the in vivo imaging agent. Further aspects of the invention include a radiopharmaceutical composition comprising the in vivo imaging agent of the invention, and methods for the use of said in vivo imaging agent.
The present invention provides a method useful in the diagnosis and monitoring of cancer wherein there is an abnormal expression of PBR. The method of the invention is particularly useful in evaluating the severity of the cancer, e.g. PBR expression correlates with cell proliferation rates, metastatic potential, tumor aggressiveness, malignancy progression. The method of the invention can therefore be applied in the determination of likely disease progression and in making an associated prognosis. Furthermore, the method of the invention can find use in determining the likely success of certain therapeutic approaches, or in the evaluation of the efficacy of certain proposed new treatments.
The present invention provides a method useful in the diagnosis and/or monitoring of mood disorders wherein there is an abnormal expression of PBR. The method of the invention is useful in the differential diagnosis of said mood disorders and other conditions where there is no abnormal expression of PBR but where the symptoms may be similar to those of said mood disorder.

photolysis of 2-alkenylcarboxamido-2-cycloalken-1-ones led regio- and stereospecifically to a faster [2+2] intramolecular reaction and therefore to the corresponding cyclobutanes. However, photorearrangements involving three different intramolecular H-abstraction processes, compete with the observed cycloaddition. To explain the results, we propose that different deactivation pathways are available
