新型硫脲(5a,5b)和噻唑烷酮衍生物(6a,6b)是通过从化合物6-(4-苯基哌嗪-1-基)吡啶-3-胺(4)起始的分子杂交而合成的,已知该化合物显示出抗癌活性。通过使用1-(5-硝基吡啶-2-基)-4-苯基哌嗪(3)进行合成,该化合物是通过2-氯-5-硝基吡啶的新型反应方法获得的(1)。和N-苯基哌嗪(2)。使用FTIR,1 H NMR,13 C NMR,HRMS光谱法和元素分析确认化合物的结构。测试了有机分子对前列腺癌(PC)细胞系DU 145,PC-3和LNCaP的抗癌活性。由于化合物5a发挥最高的细胞毒活性,因此需要进一步研究化合物5a的IC50浓度,以观察其形态,PC细胞系的集落形成能力,RNA表达,DNA片段化和细胞周期分布。总体数据显示,化合物5a处理可诱导PC细胞株凋亡和DNA片段化,并抑制细胞周期进程,导致细胞在G1或S期积累。

reaction of heteroarylchlorides in the pyrimidine, pyrazine and quinazoline series with amines in water in the presence of KF results in a facile SNAr reaction and N‐arylation. The reaction is less satisfactory with pyridines unless an additional electron‐withdrawing group is present. The results showed that the transition‐metal‐free SNAr reaction not only compares favourably to palladium‐catalysed
嘧啶、吡嗪和喹唑啉系列中的杂芳基氯化物与水中的胺在 KF 存在下发生反应,导致容易的 S N Ar 反应和N芳基化。除非存在额外的吸电子基团,否则吡啶的反应不太令人满意。结果表明,无过渡金属的 S N Ar 反应不仅优于钯催化的偶联反应,而且在碱和溶剂方面也可以在环境可接受的(“绿色”)条件下进行。

2-chloro-5-nitropyridine (1) and N-phenylpiperazine (2). The structures of the compounds were confirmed using FTIR, 1HNMR, 13CNMR, HRMS spectroscopic methods and elemental analysis. The organic molecules were tested for their anticancer activities against prostate cancer (PC) cell lines: DU 145, PC-3 and LNCaP. As the compound 5a exerted the highest cytotoxic activity, IC50 concentrations of compound 5a were

6-(4-phenylpiperazin-1-yl)pyridin-3-ylamine (4) was converted to compound 5, an active intermediate compound, by substitution of one of the amine hydrogens with ethyl bromoacetate. The resulting ester product (5) followed by the hydrazidation (6) was added arylisocyanate to obtain the active intermediate (8). Then, by a series of substitution through cyclization and condensation reactions, thiazolidinone (9),
