摘　　要：4＂,7-Dimethoxy-N-methylisoflavone-3＂-sulfonamide （3） was synthesized by a two step synthesis method and characterized via IR and 1H NMR. Its chemical structure was determined by X-ray single-crystal diffraction. It crystallizes in monoclinic, space group C2/c with a = 27.677（13）, b= 10.490（5）, c = 13.982（7） A, β = 118.781 （9）°, V = 3558（3） A3, Z = 8, F（000） = 1568, Dc = 1.401 Mg/m3, Mr = 375.39,/t = 0.217 mm-1, 2 = 0.71073 A, the final R = 0.0436 and wR = 0.0910 for 3168 observed reflections with 1〉 2δ（/）. The compound was studied subsequently for the potent neuroprotective activity, and showed effects against oxygen-glucose deprivation injury in PC12 cells in a dose-dependent manner （protection： 42.5% at 100 μg-mL-1, 35.1% at 10 μg-mL-1 and 22.5% at 1 μg·mL-1）.
