Synthesis,Crystal Structure and Antiproliferative Activity of Ethyl 1-（Phenylcarbamoyl）-2-3,4,5-trimethoxyphenyl）cyclopropanecarboxylae

Many small-molecule compounds have been evaluated with potential antiproliferative activities. Ethyl 1-(phenylcarbamoyl)-2-(3,4,5-trimethoxyphenyl)cyclopropanecarboxylate, one novel cyclopropylamide analogue of combretastatin-A4(CA-4), has been synthesized and its crystal structure was characterized by X-ray single-crystal diffraction. The crystal belongs to monoclinic, space group P21/n, with a = 15.0263(3), b = 7.6574(2), c = 19.4117(4), β = 111.9010(10)o, V = 2072.36(8)3, Z = 4, C22H24NO6, Mr = 398.42, Dc = 1.277 Mg/cm3, F(000) = 844, λ(MoKα) = 1.54178 , μ = 0.770 mm–1, R = 0.0546 and wR = 0.1889 for 3319 observed reflections(I 2σ(I)). Meanwhile, the compound revealed potential antiproliferative activities in several cancer cells in vitro.
