According to our previous work and the latest research on the biosynthesis of β-carboline, and using the reverse thinking strategy, tryptophan, the biosynthesis precursor of β-carboline alkaloids, and their derivatives were synthesized, and their biological activities and structure–activity relationships were studied. This bioassay showed that these compounds exhibited good inhibitory activities against
根据我们先前对β-咔啉生物合成的研究和最新研究,并采用逆向思维策略,合成了色氨酸,β-咔啉生物碱的生物合成前体及其衍生物,以及它们的生物活性和构效关系被研究了。这项生物测定结果表明,这些化合物对烟草花叶病毒(TMV)表现出良好的抑制活性。尤其是(S)-2-氨基-3-(1 H-吲哚-3-基)-N-辛基丙酰胺(4)(63.3±2.1%,67.1±1.9%,68.7±1.3%和64.5±3.1%, 500μg/ mL)在体外和体内均表现出最佳的抗病毒活性。化合物4选择该化合物用于野外试验和急性口服毒性试验,结果表明该化合物在野外具有良好的抗TMV活性,而急性口服毒性较低。我们还发现这些化合物显示出抗真菌活性和杀虫活性。
