A series of 3-substituted spiro[(dihydropyrazine-2,5-dione)-6,3'-(2',3'-dihydrothieno[2,3-b]naphtho-4',9'-d ione)] derivatives were prepared using an easy synthetic route via condensation of the 3-amino-3-(ethoxycarbonyl)-2,3-dihydrothieno[2,3-b]naphtho-4,9-dione system and amino acids followed by intramolecular lactamization. Amino acids containing alkyl and aryl, linear and cyclic, polar and apolar
一系列3-取代的螺[(二氢吡嗪-2,5-二酮)-6,3'-(2',3'-二氢噻吩并[2,3-b]萘-4',9'-d离子)]使用3-氨基-3-(乙氧基羰基)-2,3-二氢噻吩并[2,3-b]萘-4,9-二酮系统与氨基酸的缩合反应,然后通过分子内酰胺化,通过简单的合成途径制备衍生物。掺入了含有烷基和芳基,线性和环状,极性和非极性以及碱性和酸性残基的氨基酸。对MCF-7人乳腺癌和SW 620人结肠癌细胞系的这些类似物进行评估后发现,它们源自Pro(7a),Cys(11a)和Met(12a)和3R的3S,3'R异构体D-Pro(7c)衍生的,3'S异构体,其细胞毒性效力与阿霉素相当或更高。这些选择的类似物中的一些在其他几种敏感和耐药的人类实体瘤细胞系中是有效的细胞毒性剂,并且可能能够规避多重耐药机制。特别是,在已知对阿霉素(MCF-7 / Dx和A2780 / Dx)有抗性的所选肿瘤细胞亚系中,仅
