first compound, 1-phenyl-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline hydrochloride (3a), showed the highest toxicity with LD50 of 280 mg/kg in contrast to 1-(3'-bromo -4'-hydroxyphenyl)-6,7-methylenedioxy-1,2,3,4-tetrahydroisoquinoline hydrochloride (3e) which proved to be the safest of the compounds studied. Its toxicity was 13.75 times lower than that of the parent compound 3a. All compounds investigated
异喹啉生物碱是最常见的生物碱类之一,在治疗各种疾病方面表现出显着的作用。寻找降低这些分子毒性并增加其治疗范围的方法是当务之急。在这里,通过 Pictet-Spengler 反应,一步法合成一系列 1-aryl-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinolines,收率为 85-98%。这是使用 3,4-二甲氧基苯乙胺与取代的苯甲醛在三氟乙酸中沸腾的反应完成的。此外,通过 1-(3'- nitro-, 4'-nitrophenyl)-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinolines with SnCl2 × 2H2O。所得物质的结构通过红外 (IR) 和核磁共振 (1H 和 13C NMR) 光谱得到证实。ADMET/TOPKAT in silico 研究得出结论,合成的化合物表现出可接受的药效学和药代动力学特性
