The synthesis of new 1,4-bisalkylamino (2–4) and 1-alkylamino-4-chloro (5–6) substituted benzo[g]phthalazines is reported. Compounds 2–4 and 6 were prepared both in the free and heteroaromatic ring protonated forms. Bifunctional 6 contains the 1,4-bisaminopropylpiperazine chain as a linker between the two heteroaromatic units, whereas 5 is its monofunctional analogue. The in vitro antitumour activity
新的1,4- bisalkylamino(合成2 - 4和1-烷基氨基-4-氯()5 - 6 -苯并[取代)克报道]酞嗪。化合物2 - 4和6在自由和杂芳环质子化形式的制备两者。双功能6包含1,4-双氨基丙基哌嗪链作为两个杂芳族单元之间的连接基,而5是其单功能类似物。已经测试了合成化合物在体外对人结肠癌,乳腺癌和肺癌细胞以及对人胶质母细胞瘤细胞的抗肿瘤活性。获得的结果表明,它们在所有情况下均具有活性,但双功能6 ·2HCl对测试的四种细胞系具有显着效果 ,与阿霉素相似,IC 50值在10 -7 M范围内。6 ·2HCl的双官能结构相对于单官能相关化合物5和7增强了活性,从而在所有测试的化合物中产生了最高的活性。6的分子模型提示这些结果可能表明DNA双插入,特别适合双质子化形式6 ·2HCl,该化合物适合在进一步的生物学测试中进行更深入的研究。DNA热解曲线的测量结果表明,双功能6 ·2HCl的T
