  • Publication number: 20080193380
    Abstract: Provided is a class of radiolabeled androgen receptor targeting agents (ARTA), useful for prostate cancer imaging and in treating or preventing prostate cancer. The agents define a new subclass of radiolabeled compounds, which are selective androgen receptor modulators (SARM), which demonstrate antiandrogenic activity of a nonsteroidal ligand for the androgen receptor, and/or which bind irreversibly to the androgen receptor. The present invention further provides methods for a) imaging of cancer in a subject, b) imaging an androgen receptor-containing tissue in a subject, c) in-vivo imaging in a subject, d) treating a subject suffering from prostate cancer, e) delaying the progression of prostate cancer in a subject suffering from prostate cancer, f) preventing the recurrence of prostate cancer in a subject suffering from prostate cancer, and g) treating the recurrence of prostate cancer in a subject suffering from prostate cancer, which comprise using the radiolabeled compounds of the present invention.

  • Publication number: 20040087810
    Abstract: In one embodiment, this invention provides a class of androgen receptor targeting agents (ARTA). The agents define a new subclass of compounds, which are selective androgen receptor modulators (SARM). The SARM compounds have unexpected antiandrogenic activity of a nonsteroidal ligand for the androgen receptor. In one embodiment, the SARM compounds bind irreversibly to the androgen receptor. In another embodiment, the SARM compounds are androgen receptor antagonists which bind irreversibly to the androgen receptor. In another embodiment, the SARM compounds are alkylating agents.
