  Synthesis of Novel 4H-Chromenes Containing a Pyrimidine-2-Thione Function in the Presence of Fe₃O₄ Magnetic Nanoparticles and Study of Their Antioxidant Activity

  摘要：

  The aim of the present work was to search for identification of novel reactive oxygen species (ROS) scavengers by testing new fused chromenopyrimidinethiones, which was synthesized using Fe3O4 nanoparticles. The new compounds were also tested for their cytotoxic activity. The obtained results showed that the incorporated pyrimidinethione moiety significantly increase antioxidant activity. In conclusion, the study of the pharmacological properties of the new chromenopyrimidinethiones allowed establishing new structure-activity relationships for splitting antioxidant and cytotoxic activity of these compounds.

  Src kinase mutations and/or overexpression have been implicated in the development of a number of human cancers including colon, breast, and lung cancers. Thus, designing potent and selective Src kinase inhibitors as anticancer agents is a subject of major interest. A series of 4-aryl substituted derivatives of 2-amino-7-dimethylamino-4H-chromene- 3-carbonitrile were synthesized using one-pot reaction of appropriate substituted aromatic aldehydes, malononitrile, and 3-(dimethylamino)phenol in the presence of piperidine. All 23 compounds were evaluated for inhibition of Src kinase and cell proliferation in human colon adenocarcinoma (HT-29) and leukemia (CCRF-CEM) cell lines. Among the tested compounds, 2-chlorophenyl- (4c), 3-nitrophenyl- (4h), 4-trifluoromethyphenyl- (4i), and 2,3-dichlorophenyl- (4k) substituted chromenes showed Src kinase inhibitory effect with IC50 values of 11.1-18.3 μM. Compound 4c was relatively selective against Src (IC50 = 11.1 μM), when compared with selected kinases, epidermal growth factor receptor (EGFR, IC50 300 μM), C-terminal Src kinase (Csk, IC50 = 101.7 μM), and lymphocyte-specific protein tyrosine kinase (Lck, IC50 = 46.8 μM). 3-Chlorophenyl substituted thiazole (4v) and 2-chlorophenylsubstituted thiazole (4u) chromene derivatives inhibited the cell proliferation of HT-29 and CCRF-CEM by 80% and 50%, respectively, at a concentration of 50 μM. The data indicate that 4H-chromene-3-carbonitrile scaffold has the potential to be optimized further for designing more potent Src kinase inhibitors and/or anticancer lead compounds.

  Src 激酶突变和/或过度表达与结肠癌、乳腺癌和肺癌等多种人类癌症的发病有关。因此，设计强效且具有选择性的 Src 激酶抑制剂作为抗癌药物是一个备受关注的课题。在哌啶的存在下，利用适当取代的芳香醛、丙二腈和 3-（二甲基氨基）苯酚的一锅反应，合成了一系列 2-amino-7-dimethylamino-4H-chromene- 3-carbonitrile 的 4-芳基取代衍生物。对所有 23 种化合物在人结肠腺癌（HT-29）和白血病（CCRF-CEM）细胞系中对 Src 激酶和细胞增殖的抑制作用进行了评估。在测试的化合物中，2-氯苯基（4c）、3-硝基苯基（4h）、4-三氟甲基苯基（4i）和 2,3-二氯苯基（4k）取代的色烯类化合物具有抑制 Src 激酶的作用，IC50 值为 11.1-18.3 μM。与选定的激酶、表皮生长因子受体（EGFR，IC50 300 μM）、C-末端 Src 激酶（Csk，IC50 = 101.7 μM）和淋巴细胞特异性蛋白酪氨酸激酶（Lck，IC50 = 46.8 μM）相比，化合物 4c 对 Src 具有相对的选择性（IC50 = 11.1 μM）。3-氯苯基取代的噻唑（4v）和 2-氯苯基取代的噻唑（4u）色烯衍生物在 50 μM 浓度下分别抑制 HT-29 和 CCRF-CEM 细胞增殖 80% 和 50%。这些数据表明，4H-色烯-3-甲腈支架具有进一步优化的潜力，可用于设计更有效的 Src 激酶抑制剂和/或抗癌先导化合物。

  A novel magnetically separable catalyst was prepared based on surface modification of Fe304 magnetic nanoparticle (IVINPs) with polyethyleneimine (PEI) via covalent bonding. 13-(2,3-Epoxypropoxy)propyl] trimethoxysilane (EPO) was used as cross linker to bond PEI on the surface of MNPs with permanent stability in contrast to PEl coating via electrostatic interactions. The synthesized catalyst was characterized by Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA). X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM). The catalyst show high efficiency for one-pot synthesis of 2-amino-3-cyano 4/1 pyran derivatives via multi-component reaction (MCR). This procedure offers the advantages of green reaction media, high yield, short reaction time, easy purification of the products and simple recovery and reuse of the catalyst by simple magnetic decantation without significant loss of catalytic activity.
