A new route to 3-(4-arylmethylamino)butyl-5-arylidene-2-thioxo-1,3-thiazolidine-4-one 9 was developed in six steps from commercial 1,4-diaminobutane 1 as starting material. The key step of this multi-step synthesis involved a solution phase “one-pot two-steps” approach assisted by microwave dielectric from N-(arylmethyl)butane-1,4-diamine hydrochloride 6a–f (as source of the first point diversity) and commercial bis-(carboxymethyl)-trithiocarbonate reagent 7 for construction of the rhodanine platform. This platform was immediately functionalized by Knoevenagel condensation under microwave irradiation with a series of aromatic aldehydes 3 as second point of diversity. These new compounds were prepared in moderate to good yields and the fourteen synthetic products 9a–n have been obtained with a Z-geometry about their exocyclic double bond. These new 5-arylidene rhodanines derivatives 9a–n were tested for their kinase inhibitory potencies against four protein kinases: Human cyclin-dependent kinase 5-p25, HsCDK5-p25; porcine Glycogen Synthase Kinase-3, GSK-3α/β; porcine Casein Kinase 1, SsCK1 and human HsHaspin. They have also been evaluated for their in vitro inhibition of cell proliferation (HuH7 D12, Caco 2, MDA-MB 231, HCT 116, PC3, NCI-H727, HaCat and fibroblasts). Among of all these compounds, 9j presented selective micromolar inhibition activity on SsCK1 and 9i exhibited antitumor activities in the HuH7 D12, MDA-MBD231 cell lines.
以商用 1,4-二氨基丁烷 1 为起始原料,通过六个步骤开发出了 3-(4-芳基甲基氨基)丁基-5-芳基亚甲基-2-硫酮-1,3-噻唑烷-4-酮 9 的新路线。这一多步骤合成的关键步骤是在微波介质的辅助下,采用溶液相 "一锅两步法",从 N-(芳基甲基)丁烷-1,4-二胺盐酸盐 6a-f(作为第一点多样性的来源)和商用双(羧甲基)-三硫代碳酸酯试剂 7 开始,构建罗丹宁平台。在微波辐照下,该平台立即与一系列芳香醛 3(作为第二点多样性)通过克诺文纳格尔缩合作用实现了官能化。这些新化合物的制备收率从中等到良好,并获得了 14 个合成产物 9a-n,其外环双键具有 Z 几何结构。测试了这些新的 5-芳基罗丹宁衍生物 9a-n 对四种蛋白激酶的激酶抑制效力:这四种蛋白激酶是:人细胞周期蛋白依赖性激酶 5-p25(HsCDK5-p25)、猪糖原合成酶激酶 3(GSK-3α/β)、猪酪蛋白激酶 1(SsCK1)和人 HsHaspin。此外,还对这些化合物体外抑制细胞增殖的能力进行了评估(HuH7 D12、Caco 2、MDA-MB 231、HCT 116、PC3、NCI-H727、HaCat 和成纤维细胞)。在所有这些化合物中,9j 对 SsCK1 具有选择性微摩尔抑制活性,9i 在 HuH7 D12 和 MDA-MBD231 细胞系中具有抗肿瘤活性。
