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 …

The synthesis and evaluation of structure-activity relationships of saturated nitrogen heterocycles is the focal point of various pharmaceutical companies thanks to the high biological activity of previously isolated azacycles. Here, we describe an operationally simple and highly efficient approach to macrocyclic lactams bearing vicinal stereocenters and a challenging cycloalkyne motif. The outcomes are achieved through a novel [4 + 2] cycloaddition reaction between an N-iodoarylated-1,3-azadiene and cyclic anhydrides, followed by interception of the cycloadducts in cross-coupling manifolds (e.g., Sonogashira coupling) and concomitant lithiation-cyclization of the tethered alkyne. An unprecedented example of a hydroamino alkylation that is transition …
