Spongian diterpenoids inhibit androgen receptor activity.

Androgen receptor is a ligand-activated transcription factor and a validated drug target for all stages of prostate cancer. Antiandrogens compete with physiologic ligands for androgen receptor ligand-binding domain (LBD). High-throughput screening of a marine natural product library for small molecules that inhibit androgen receptor transcriptional activity yielded the furanoditerpenoid spongia...

Pregnane X receptor as a therapeutic target to inhibit androgen activity.

The androgen-androgen receptor signaling pathway plays an important role in the pathogenesis of prostate cancer. Accordingly, androgen deprivation has been the most effective endocrine therapy for hormone-dependent prostate cancer. Here, we report a novel pregnane X receptor (PXR)-mediated and metabolism-based mechanism to reduce androgenic tone. PXR is a nuclear receptor previously known as a ...

Androgen receptor coactivators that inhibit prostate cancer growth.

It is well documented that androgen receptor (AR), a steroid hormone receptor, is important for prostate cancer (PCa) growth. Conversely, however, there is increasing evidence that activation of AR by androgens can also lead to growth suppression in prostate cells. AR mediated transcription is regulated by a number of different transcriptional coactivators. Changes in expression level or cellul...

Characterization of Niphatenones that Inhibit Androgen Receptor N-Terminal Domain

Androgen ablation therapy causes a temporary reduction in tumor burden in patients with advanced prostate cancer. Unfortunately the malignancy will return to form lethal castration-recurrent prostate cancer (CRPC). The androgen receptor (AR) remains transcriptionally active in CRPC in spite of castrate levels of androgens in the blood. AR transcriptional activity resides in its N-terminal domai...

Decoy androgen-responsive element DNA can inhibit androgen receptor transactivation of the PSA promoter gene.

Chemotherapy, hormonal therapy, or surgery may cause devastating toxic or other side effects. Androgen receptors (ARs) in the cytoplasm are activated by binding with androgen. Androgen-activated ARs bind to a specific genomic DNA sequence, the androgen-responsive element (ARE), and initiate gene expression at the transcriptional level. Even without androgen activation, ARs may have a role in an...
