Starting from benzofuran-2-methanal, 6-substituted benzothiazole-2-amines and malonic esters, sixteen title compounds were designed and synthesized seeking to introduce anti-TMV activity. The structures of the newly synthesized compounds were confirmed by 1H-NMR, 13C-NMR, IR spectra, and MS (HREI) analysis. The bioassays identified some of these new compounds as having moderate to good anti-TMV activity. The compounds 5i and 5m have good antiviral activity against TMV with a curative rate of 52.23% and 54.41%, respectively, at a concentration of 0.5 mg/mL.
从苯并呋喃-2-甲醛、6-取代苯并噻唑-2-胺和丙二酸酯出发,设计并合成了十六种目标化合物,以期引入抗TMV活性。新合成化合物的结构通过1H-NMR、13C-NMR、红外光谱和质谱(HREI)分析得到确认。生物测试显示,其中一些新化合物具有中等至良好的抗TMV活性。化合物5i和5m在浓度为0.5 mg/mL时,对TMV的治愈率分别为52.23%和54.41%,表现出良好的抗病毒活性。
