or a pharmaceutically acceptable salt, tautomer or stereoisomer thereof, wherein R.sup.1, R.sup.2, R.sup.3, R.sup.11a, R.sup.11b, R.sup.11c, R.sup.11d, X, n.sup.1, n.sup.2, and n.sup.3 are as defined herein, are provided. Uses of such compounds for modulating androgen receptor activity, imaging diagnostics in cancer and therapeutics, and methods for treatment of subjects in need thereof, including prostate cancer are also provided.

The present invention relates to a solid precursor in the form of an organic salt, the solid precursor having a solid support, a method for manufacturing same, and an application thereof. The solid precursor of the present invention enables omission of the [.sup.18F]fluoride refining process using additional cartridge, and the use of excessive phase-transfer catalyst, and can easily remove remaining substance after reaction through the solid support inside the precursor. The solid precursor of the present invention is very appropriate for an automated synthesis device as an all-in-one system that can carry out overall process of [.sup.18F]fluorosis reaction, when used by charging in a cartridge.

The present invention generally relates to various compounds that are useful as -synuclein ligands. The invention further relates to methods of using these compounds and their radiolabeled analogs for the detection of synucleinopathies, including Parkinson's disease (PD).

The present invention relates to the use of arylalkanolamine compounds with sigma-1 receptor antagonist activity. In particular, the said arylalkanolamine compounds are useful in the treatment of conditions selected from the abuse of psychotropic substances such as cocaine or amphetamines, pain and cancer.
