We report herein the chemical synthesis and biological evaluation of β-carboline alkaloid pityriacitrin and some of its new derivatives. Using tryptophan or 5-hydroxytryptophan and 5-substituted indole-3-glyoxals as the starting materials, pityriacitrin and some of its derivatives were synthesized via the acid-catalyzed Pictet–Spengler reaction and fully characterized by 1H and 13C NMR, mass spectroscopy
我们在此报告β-咔啉生物碱Pitriacitrin及其一些新衍生物的化学合成和生物学评估。以色氨酸或5-羟基色氨酸和5-取代的吲哚-3-乙二醛为起始原料,通过酸催化的Pictet-Spengler反应合成了糠硫胞苷及其衍生物,并通过1 H和13 C NMR,质谱进行了全面表征。和红外测定。生物学研究表明,苦参碱对一组乳腺癌和前列腺癌细胞系具有较弱的抗增殖活性,而其某些衍生物表现出更强而有力的活性,这与诱导细胞凋亡和坏死有关。
