MJC13 inhibits the positive regulation of androgen receptor (AR) signaling by the cochaperone protein FKBP52. The molecule inhibits hormone-induced dissociation of the FKBP52, nuclear translocation of AR and AR dependent gene expression. MJC13 inhibits proliferation of the androgen-dependent prostate cancer cell lines LNCaP and LAPC4.

FKBP52 and β-catenin have emerged in recent years as attractive targets for prostate cancer treatment. β-catenin interacts directly with the androgen receptor (AR) and has been characterized as a co-activator of AR-mediated transcription. FKBP52 is a positive regulator of AR

MJC13, a novel FKBP52 targeting agent, has potential use for the treatment of castration-resistant prostate cancer. The purpose of this work was to develop a solution formulation of MJC13, and obtain its efficacy profile in a human prostate cancer xenograft
The growth of prostate cancer is dependent on the androgen receptor (AR), which serves as a ligand-specific transcription factor. Although two immunophilins, FKBP51 and FKBP52, are known to regulate AR activity, the precise mechanism remains unclear. We found that depletion
The androgen receptor (AR) surface-directed antagonist MJC13 inhibits AR function and proliferation of prostate cancer (PC) cells. These effects are related to arrest of an AR/chaperone complex in the cytoplasm. Here, we compared MJC13 and classic AR antagonists such as
Androgen ablation therapy is the most common treatment for advanced prostate cancer (PCa), but most patients will develop castration-resistant prostate cancer (CRPC), which has no cure. CRPC is androgen-depletion resistant but androgen receptor (AR) dependent. AR is a nuclear receptor
