develop novel β-carbolines endowed with better insecticidal activity, a simple high-yielding method for the synthesis of harmine compounds starting from L-tryptophan has been developed and a series of 1,3-substituted β-carboline derivatives have been synthesized and evaluated for their cytotoxicity against insect cultured Sf9 cell line in vitro and insecticidal activities against 4th instar larvae of mosquitos
在不断努力开发具有更好杀虫活性的新型 β-咔啉的过程中,开发了一种以 L-色氨酸为原料合成有害化合物的简单高产方法,并开发了一系列 1,3-取代的 β-咔啉衍生物合成并评估了它们对昆虫培养的 Sf9 细胞系的体外细胞毒性和对蚊子 4 龄幼虫库蚊和芥子蚜虫 Lipaphis erysimi 的杀虫活性。结果表明,1-苯基-1,2,3,4-四氢-β-咔啉-3-羧酸(化合物2)和1-苯基-β-咔啉-3-羧酸甲酯(化合物13)代表最佳潜在的化合物,在 50-200 mg/L 的浓度下处理 24 小时后,Sf9 细胞的抑制率分别为 71.55% 和 60.21%。化合物2和13对蚊子4龄幼虫也表现出较强的杀虫活性,LC(50)值为20.82 mg/L和23.98 mg/L,LC(90)值为88.29 mg/L和295.13 mg/L , 分别。此外,化合物2和13对芥菜蚜虫的LC(50)值为53.16
