commercial herbicide with very low toxicity against mammals, it is worth exploring its derivatives for an extensive study. Herein, a total of 35 novel compounds were chemically synthesized and single crystal of 6–6 was obtained to confirm the molecular structure of this family of compounds. The novel PTB derivatives were fully evaluated against various biological platforms. From the bioassay results
由于吡硫杆菌(PTB)是一种成功的商业除草剂,对哺乳动物的毒性极低,因此值得探索其衍生物以进行广泛研究。这里,总共有35种新型化合物化学合成和单晶6 - 6得到确认该化合物家族的分子结构。新型PTB衍生物已针对各种生物平台进行了全面评估。从生物测定结果来看,最好的AHAS抑制剂6-22表现出比PTB弱的除草活性,但更强的抗-念珠菌活性。对于植物病原真菌,6–26在50 mg / L剂量下显示出优异的活性。还观察到一些标题化合物的初步杀虫活性和抗病毒活性。令人惊讶的是,6-5对SARS-CoV M pro表现出有希望的抑制活性,IC 50为4.471μM,对哺乳动物293 T细胞的细胞毒性较低。基于分子建模的结果,HOMO-1被认为是影响AHAS抑制和的可能的结合模式的一个因素6 - 5与SARS-病毒M亲被预料到了。这是首次将PTB衍生物作为除草剂以外的生物制剂进行了研究。因此,本研究表明
