Deshydroxy propioanilides were synthesised by Michael addition reaction between substituted thiophenols onto four different phenylacrylamide derivatives to give twenty-three novel deshydroxy bicalutamide derivatives lacking the central hydroxyl group. The antiproliferative activities of these compounds were evaluated against human prostate cancer cell lines and thirteen compounds showed better inhibitory activities (IC50 = 2.67–13.19 μM) compared to bicalutamide (IC50 = 20.44 μM) in LNCaP. Remarkably, novel double branched bicalutamide analogues (27 and 28) were isolated as major by-products and found to have the best activity across three human prostate cancer cell lines (LNCaP, VCaP and PC3). The most active compound 28 shows sub-micromolar activity (IC50 = 0.43 μM in LNCaP), which represents more than 40-fold improvement over the clinical anti-androgen bicalutamide (IC50 = 20.44 μM) and a more than 3 fold improvement over enzalutamide (IC50 = 1.36 μM). Moreover, strong reduction of PSA expression in LNCaP cells upon treatment with compounds 27, 28 and 33 was observed during qPCR analysis, confirming their AR antagonist activity. Molecular modelling studies revealed a novel binding mode of these structurally distinct double branched analogues within the ligand binding domain (LBD) of the androgen receptor.

Prostate cancer (PC) is one of the major causes of male death worldwide and the development of new and more potent anti-PC compounds is a constant requirement. Among the current treatments, (R)-bicalutamide and enzalutamide are non-steroidal androgen receptor antagonist drugs approved also in the case of castration-resistant forms. Both these drugs present a moderate antiproliferative activity and their use is limited due to the development of resistant mutants of their biological target. Insertion of fluorinated and perfluorinated groups in biologically active compounds is a current trend in medicinal chemistry, applied to improve their efficacy and stability profiles. As a means to obtain such effects, different modifications with perfluoro groups were rationally designed on the bicalutamide and enzalutamide structures, leading to the synthesis of a series of new antiproliferative compounds. Several new analogues displayed improved in vitro activity towards four different prostate cancer cell lines, while maintaining full AR antagonism and therefore representing promising leads for further development. Furthermore, a series of molecular modelling studies were performed on the AR antagonist conformation, providing useful insights on potential protein-ligand interactions.
