Structure Activity Relationship Studies Of Novel Diarylpentanoid Analogs Targeting The Androgen Receptor In Prostate Cancer Cells, Haili Coffin, Marco Bisoffi

Student Scholar Symposium Abstracts and Posters

The development of prostate cancer (PCa) relies strongly on the activation of the androgen receptor (AR) signaling pathway by its natural ligand dihydrotestosterone. Furthermore, PCa progression to metastatic disease represents oncogene addiction to AR activity. Androgen ablation therapy is thus a mainstay therapy against this disease, but the development of ligand-independent AR activation and persisting AR expression eventually leads to castration resistant PCa (CRPC). Therefore, down-regulation of AR expression in PCa cells may be an effective therapeutic modality. The diarylpentanoid ca27 has previously been shown to down-regulate AR expression by an unknown mechanism of action. The present work represents a …

In this study, a new apoptotic monoterpenoid indole alkaloid, subditine (1), and four known compounds were isolated from the bark of Nauclea subdita. Complete 1H- and 13C- NMR data of the new compound were reported. The structures of isolated compounds were elucidated with various spectroscopic methods such as 1D- and 2D- NMR, IR, UV and LCMS. All five compounds were screened for cytotoxic activities on LNCaP and PC-3 human prostate cancer cell-lines. Among the five compounds, the new alkaloid, subditine (1), demonstrated the most potent cell growth inhibition activity and selective against LNCaP with an IC50 of 12.2460.19 mM and …
