This study covers the design, synthesis, characterization, and cytotoxic activity of a series of uracil C-Mannich bases. Among them, one hybrid compound (1), a molecular combination of the potential antimetabolite substituted uracil and nitrogen mustard, having potential alkylating capability, was prepared as a Mannich base. The other compound was synthesized with the replacement of chlorines in the ethyl chains with hydroxyl groups for testing for anticancer activity. Some of Mannich bases having several amino groups with different pKa values were also synthesized and investigated in terms of cytotoxic activity. Their chemical structures were confirmed by means of their UV, IR, ^1H-NMR, ^13}C-NMR, and MS data. Compounds 6 with diethylamine and 8 with piperazine are reported for the first time in the literature and compounds 1, 4, and 5 containing nitrogen mustard, pyrolidine, and diethanolamine, respectively, as amine function are reported for first time with detailed spectral data herein. Morpholine, piperidine, and dimethylamine were used in Mannich reactions for the synthesis of compounds 2, 3 and 7. We assessed their biological activities using MTT assays on 3 human cell lines: HeLa (cervix adenocarcinoma), MCF7 (breast adenocarcinoma), and A431 (skin epidermoid carcinoma). While compounds 2-8 have the potential to deaminate, forming ortho-quinone methides, which would be capable of alkylating cellular thiols, compound 1 has the potential to give aziridinium ion for nucleophilic alkylation. Our results are discussed in terms of the significance of these compounds in pharmaceutical use.
本研究涵盖了一系列尿嘧啶C-Mannich碱的设计、合成、表征和细胞毒活性。其中,合成了一种杂合化合物(1),它是潜在抗代谢物取代尿嘧啶和氮芥的分子组合,具有潜在的烷基化能力,作为Mannich碱制备。另一种化合物通过将乙基链中的氯原子替换为羟基以测试抗癌活性进行合成。此外,合成了一些具有不同pKa值的多个氨基的Mannich碱,并研究了其细胞毒活性。通过UV、IR、^1H-NMR、^13}C-NMR和质谱数据确认了它们的化学结构。包含二乙胺的化合物6和含哌嗪的化合物8在文献中首次报道,而包含氮芥、吡咯烷和二乙醇胺的化合物1、4和5在这里首次详细报告了光谱数据。莫尔霍林、哌啶和二甲胺用于Mannich反应,以合成化合物2、3和7。我们使用MTT实验评估了它们对三种人类细胞系的生物活性:HeLa(宫颈腺癌)、MCF7(乳腺腺癌)和A431(皮肤表皮癌)。虽然化合物2-8具有去氨基的潜力,形成可以烷基化细胞硫醇的邻苯二醇甲烷,但化合物1则有可能生成叠氮阳离子以进行亲核烷基化。我们的结果讨论了这些化合物在药物使用中的重要性。
