Abstract:
Disclosed herein are methods and compounds useful in preparing N-(3,4-dimethyl-5-isoxazolyl)-2-(4-(2-butyl-4-oxo-l,3-diazospiro[4.4]non-l-en-3yl)methyl-2-ethoxymethylphenyl)phenylsulfonamide.
Abstract:
The present invention relates to a novel class of anti-cancer compounds which selectively target androgen receptor (AR)-expressing cancer, cells, such as prostate cancer cells and breast cancer cells, These agents comprise an androgen receptor (AR) binding moiety, which selectively tar-gets the compounds to (AR)-expressing cancer cells, and a cytotoxic alkylating moiety, such as a nitrogen mustard moiety, The inherent high density expression of the androgen receptor in certain cancers, such as prostate cancer and breast cancer, is thus used as a tool to selectively increase the intracellular concentration of cytotoxic compounds, such as alkylating agents, e,g. DNA alkylating agents, by selectively targeting the agents to the AR-expressing cancer cells. These agents, either alone or in a composition, are thus useful for treating, delaying the progression of, treating the recurrence of, suppressing, inhibiting or reducing the incidence of cancers characterized by the presence of AR-expressing cells, such as prostate cancer. Accordingly, the present invention provides a) methods of selectively killing an (AR)-expressing cancer, cell; b) methods of inducing apoptosis in an (AR) expressing cancer cell; c) methods of treating a cancer characterized by the presence of AR-expressing cells in a subject; d) methods of delaying the progression of a cancer characterized by the presence of AR-expressing cells in a subject; e) methods of treating the recurrence of a cancer characterized by the presence of AR-expressing cells in a subject; f) methods of suppressing, inhibiting or reducing the incidence of a cancer characterized by the presence of'AR-expressing cells in a subject; and g) methods of treating metastasis of a cancer characterized by the presence of AR.-expressing cells in a subject; by administering to the subject or by contacting the cancer cells with a compound comprising an androgen receptor, ligand moiety and an alkylating moiety, such as the novel compounds described herein.
