COMPOSITIONS AND METHODS FOR USING ANDROGEN SIGNALING INHIBITORS
The present invention relates to the use of compositions for treating or preventing a condition in a subject by inhibiting androgen signaling. The use of composition comprises methods of treating or preventing cancer with agents that inhibit androgen signaling. The pharmaceutical composition will further comprise agents that inhibit Androgen receptor activity, transcription, or expression in a subject.
1 . A method for treating or preventing condition in a subject, comprising administering to the subject a pharmaceutical composition comprising an effective amount of an agent that inhibits androgen signaling pathway, wherein at least one agent is a small molecule represented by a compound having the chemical structure of:
2 . The method of claim 1 , wherein the method further comprises inhibiting androgen expression, androgen receptor (AR) expression or AR transcriptional activity of the said subject.
3 . The composition of claim 1 , wherein said agent comprises a targeting moiety capable of binding to the surface of a cell, wherein said targeting moiety is selected from the group consisting of aptamers, peptides, biodegradable materials, antibody-derived epitope binding domains, cellular ligands, and combination thereof.
4 . The method of claim 1 , wherein the method further comprises: determining androgen expression, AR expression, or AR transcriptional activity of the said subject.
5 . The composition of claim 1 , wherein at least one agent inhibits the binding of androgen with androgen receptors, binding of heat shock protein with androgen receptors, and/or AR transcriptional activity in a subject
6 . The composition of claim 1 , wherein at least one agent is used for the treatment or prevention of cancer, insulin resistance, dyslipidemia, hypertension, polycystic ovary syndrome, adrenal hyperplasia, cushing's disease, vascular disease, androgen insensitivity syndrome, hypospadias, gynecomastia, X-linked spinal and bulbar muscular atrophy, cryptorchidism, male infertility, alopecia, prostatic hypertrophy, female fertility, ovulation, follicular maturation, and uterine development in a subject.
7 . The composition of claim 1 , wherein at least one agent is administered in nanoparticles containing an imaging agent with or without a targeting agent.
8 . The composition of claim 1 , wherein at least one agent is administered to the subject in combination with one or more chemotherapeutic drugs, immunotherapy, or radiation for treatment or prevention of cancer.
9 . The composition of claim 1 , wherein said agent can be modified by at least one functional group which includes hydroxyl, methyl, carbonyl, carboxyl, amino, nitro, ether, phosphate, sulfhydryl, fluromethyl, ester, and carbonyl group.
10 . The method of claim 9 , wherein the method further comprises inhibiting androgen expression, AR expression, or AR transcriptional activity of the said subject.
11 . The composition of claim 9 , wherein said agent comprises a targeting moiety capable of binding to the surface of a cancer cell, wherein said targeting moiety is selected from the group consisting of aptamers, peptides, biodegradable materials, antibody-derived epitope binding domains, cellular ligands, and combination thereof.
12 . The method of claim 9 , wherein the method further comprises: determining androgen expression, AR expression, or AR transcription activity of the said subject.
13 . The composition of claim 9 , wherein at least one agent inhibits the binding of androgen with androgen receptors, binding of heat shock protein with AR, and/or AR transcriptional activity in a subject
14 . The composition of claim 9 , wherein at least one agent is used for the treatment or prevention of cancer, insulin resistance, dyslipidemia, hypertension, polycystic ovary syndrome, adrenal hyperplasia, cushing's disease, vascular disease, androgen insensitivity syndrome, hypospadias, gynecomastia, X-linked spinal and bulbar muscular atrophy, cryptorchidism, male infertility, alopecia, prostatic hypertrophy, female fertility, ovulation, follicular maturation, and uterine development in a subject.
15 . The composition of claim 9 , wherein at least one agent is administered in nanoparticles containing an imaging agent with or without a targeting agent.
16 . The composition of claim 9 , wherein at least one agent is administered to the subject in combination with one or more chemotherapeutic drugs, immunotherapy, or radiation.
