Here, a series of β-amino acid ester derivatives containing quinazoline and benzothiazoles was synthesized and evaluated for anti-tobacco mosaic virus (TMV) activity. The compounds 3n, 3o, 3p and 3q showed good antiviral activity against TMV at a concentration of 500 μg/mL, with curative rates of 55.55%, 52.32%, 52.77% and 50.91%, respectively, and protection rates of 52.33%, 55.96%, 54.21% and 50
在此,合成了一系列包含喹唑啉和苯并噻唑的β-氨基酸酯衍生物,并评估了其抗烟草花叶病毒(TMV)的活性。化合物3n,3o,3p和3q在500μg/ mL的浓度下对TMV表现出良好的抗病毒活性,治愈率分别为55.55%,52.32%,52.77%和50.91%,保护率分别为52.33%,55.96%,54.21%和50.98% 。这些值接近市售的抗病毒剂宁南霉素(其治愈率和保护率分别为55.27%和52.16%)。据我们所知,这是关于含喹唑啉和苯并噻唑部分的β-氨基酸酯衍生物的抗TMV活性的首次报道。结果表明,这些新型化合物可以潜在地用作针对TMV疾病的保护剂。
