(Dichroa febrifuga). In this paper, the synthesis of a series of novel isofebrifugine analogues was accomplished by employing the N-alkylation of 4(3H)-quinazolinones with benzyl (3aR,7aR)-rel-2- (bromomethyl)hexahydrofuro[3,2-b]pyridine-4(2H)carboxylates and the subsequent N-deprotection. These analogues were characterized by 1H NMR, 13C NMR and HRMS spectra. The MTT assay was used to examine the inhibitory
从中草药常山(Dichroa febrifuga)中分离得到异氟苯丙氨酸,它是一种具有重要生理活性和良好药理作用的天然喹唑啉酮生物碱。在本文中,通过使用4(3H)-喹唑啉酮与苄基(3aR,7aR)-rel-2-(溴甲基)六氢呋喃[3,2-b]的N-烷基化反应,完成了一系列新型异氟苯丙氨酸类似物的合成。 ]吡啶-4(2H)羧酸酯化,随后进行N-脱保护。这些类似物通过1 H NMR,13 C NMR和HRMS光谱进行表征。使用MTT测定法检查这些类似物对人肝癌细胞(HepG2)生长的抑制作用。结果表明,某些卤代或半缩酮类似物显示出令人感兴趣的抑制活性。
