摘要
A series of novel 2-amino-1,3-thiazole-4-carboxylic acid derivatives were designed and synthesized.Their structures were confirmed by melting points, IR,1H NMR,13 C NMR, and HRMS or elemental analysis. Biological activities of all title compounds including fungicidal activity and antivirus activity were evaluated systematically. Preliminary bioassays indicated that these compounds exhibited good fungicidal activity at 50 mg/m L, compounds 4b and 4i exhibited over 50% activity against six fungi tested.Most compounds showed good activity against TMV with different models in vivo at 100 mg/m L.Compounds 4c and 4e stood out with high effects against TMV in vivo in all models tested, including protective, inactivative, curative, and inductive activities. These data demonstrate a new strategy for fungi and virus control.
