Abstract: Title compound (E)-1-(4-(4-bromobenzyl)piperazin-1-yl)-3-(4-chlorophenyl)prop-2-en-1-one (5) (C20H20BrClN2O, Mr?=?419.74) is designed, synthesized, and evaluated for its biological activity. Its structure is confirmed by FTIR, 1H and 13C NMR, HRMS, and X-ray single crystal diffraction. The structure is stabilized via inter- as well as intra- C–H…O interactions and intra hydrogen bonding C–H…N interactions. The Hirshfeld surface intermolecular interactions are studied using the crystal structure. The maximum surface area of the molecule is occupied by C–H…O interactions. In addition, the biological activity in vitro and in vivo of title compound 5 is also evaluated.

A new series of cinnamide derivatives 6a–l were synthesized by the reaction of acyl chlorides with various substituted benzylpiperazines. The structures were characterized by 1H NMR, 13C NMR, and HRMS. The potential neuroprotective activities of cinnamide analogs were evaluated in differentiated rat pheochromocytoma cells (PC12 cells) and in mice subjected to acute cerebral ischemia. Among the series, 6a, 6b, and 6c, featuring a 1,3-benzodioxole moiety, showed potent neuroprotection both in vivo and in vitro. The three compounds were selected and further studied to determine their mechanism of action. MTT assay, Hoechst 33342/PI double staining, and high content screening (HCS) revealed that pretreatment of the cells with 6a, 6b, and 6c has significantly decreased the extent of cell apoptosis in a dose-dependent manner. The results of western blot analysis demonstrated these compounds suppressed apoptosis of glutamate-induced PC12 cells via caspase-3 pathway. These compounds can be lead compounds for further discovery of neuroprotective agents for treating cerebral ischemic stroke.
