HE3235 inhibits growth of castration-resistant prostate cancer.

ABSTRACT: Treatments for advanced prostate cancer (CaP) typically involve androgen deprivation therapy. However, most patients eventually develop castration-resistant CaP (CRPC) for which highly effective therapies are limited. We explored the efficacy of a novel agent, HE3235, in inhibiting growth of CRPC in preclinical models. Castrated male mice were implanted subcutaneously with LuCaP35V CaP xenografts in the presence and absence of 5'-androstenediol (AED) and treated with HE3235. To investigate the effect of HE3235 on CaP tumor in the bone, castrated mice were injected intratibially with C4-2B CaP cells and treated with HE3235. Serum prostate-specific antigen (PSA) levels, tumor volume, immunohistochemistry, gene expression, and levels of intratumoral androgens were analyzed. HE3235 significant
