Abstract

In connection with our continued research to generate new aza-fused heteroaromatic chemical scaffolds, we developed a highly atom-economical three-component route to novel 3,4-dihydropyrrolo[1,2-a]pyrazine ring skeleton multi-functionalized on the pyrazine unit. This [4+1+1] annulation approach led us to gain access to a new N-fused bicyclic chemical space having two distinctive functional groups (heteroaryl and aroyl) in a trans manner. Investigation of anticancer activity of the synthesized compounds and their derivatives revealed that (3R*,4S*)-3-(4-bromophenyl)-4-(4-fluorobenzoyl)-2-(2-oxo-2-phenylethyl)-3,4-dihydropyrrolo[1,2-a]pyrazin-2-ium bromide (3h) has potent anticancer activity. 3h significantly inhibited cell viability in prostate cancer cells (PC-3) and breast cancer cells (MCF-7) with IC50 value of 1.18 ± 0.05 μM and 1.95 ± 0.04 μM, respectively. In addition, 3h strongly reduced cell migration in a dose dependent manner, and induced apoptosis via caspase-3 activation and cleavage of PARP in PC-3 and MCF-7 cells. Our results in this study imply that 3h can be a potential anticancer agent against prostate cancer and breast cancer.
