The crystal structure of the new cinnamide derivative(E)-1-(4-(4-chlorobenzyl)piperazin-1-yl)-3-(benzo[d][1,3]dioxol-5-yl)prop-2-en-1-one(C_(21)H_(21)ClN_2O_3, Mr = 384.85) was determined by single-crystal X-ray diffraction method. Compound 5 crystallizes in the monoclinic system, space group P21/c with a = 11.762(2), b = 15.279(3), c = 11.865(2) ?, β = 116.57(3)°, V = 1907.1(7) ?3, Z = 4, Dc = 1.340 g/cm3, F(000) = 808, μ = 0.224 mm-1, Mo Kα radiation(λ = 0.71073 ?), the final R = 0.0565 and w R = 0.1479 for 2318 observed reflections with I > 2σ(I). Intramolecular C(9)–H(9A)···O(1) interactions as well as intermolecular C(16)–H(16A)···O(1) hydrogen bonds help to stabilize the crystal structure. The bioassay results indicated that the title compound displayed promising neuroprotection in vitro and in vivo, and suppressed apoptosis of glutamate-induced PC12 cells.
The crystal structure of the new cinnamide derivative (E) -1- (4- (4-chlorobenzyl) piperazin-1 -yl) -3- (benzo [d] [1,3] dioxol-5-yl) (C_ (21) H_ (21) ClN_2O_3, Mr = 384.85) was determined by single-crystal X-ray diffraction method. Compound 5 crystallizes in the monoclinic system, space group P21 / c with a = 11.762 B = 15.279 (3), c = 11.865 (2)?, Β = 116.57 (3) °, V = 1907.1 (7)? 3, Z = 4, Dc = 1.340 g / cm3, F (K = 0.71073), the final R = 0.0565 and w R = 0.1479 for 2318 observed at reflections with I> 2σ (I). Intramolecular C (9) -H (9A) ··· O (1) interactions as well as intermolecular C (16) -H (16A) ··· (1) hydrogen bonds help to stabilize the crystal structure. The bioassay results indicate that the title compound demonstrated neuroprotection in vitro and in vivo, and suppressed apoptosis of glutamate-induced PC12 cells.
