In contrast to other coumarin-based inhibitors, osthole-derived compounds with extended C8-substitutions, interact with the SP1 pocket in a novel and distinct manner. These findings validate our design strategy of enhancing SP1 pocket binding to improve AKR1C3 selectivity over other AKR1C isoforms, and provide valuable structural insights for the further development of selective AKR1C3 inhibitors as potential therapeutics for CRPC.

Sixteen-week-old mice underwent surgical and chemical castration (10 mg/Kg enzalutamide), alone or in combination with JPE (5.8 g/Kg)...Mechanistically, JPE-induced effects in castrated mice involved decrease of AR protein expression as well as ERβ beneficial actions, which included a putative stimulation of TGF-β tumor-suppressive actions. In conclusion, JPE prevented the progression of poorly differentiated tumors with CRPC traits in the TRAMP model by hampering EMT and modulating steroid hormone and TGF-β signaling.
The results indicate that NUSAP1 enhanced prostate cancer ENZ resistance through activation of the Wnt/β-Catenin-AR/AR-V7 signalling pathway. Targeting NUSAP1 could offer a potential therapeutic approach to address ENZ resistance in CRPC.
