2-(5-Arylidene-4-oxo-3-phenyl-thiazolidin-2-ylidene)-3-oxo-propionitriles 4a–j were prepared via condensation of aromatic aldehydes with 4-thiazolidinones 3a, b. The latter was obtained via electrophilic attack of phenylisothiocyanate on 3-oxo-propionitriles 1a, b followed by reaction with chloroacetyl chloride under basic condition. Additionally, 2-(5-heteroalicyclic methylene) analogues 5a–h were prepared via Mannich reaction of the appropriate secondary amines and formaldehyde with 4-thiazolidinones 3a, b. Many of the synthesized compounds exhibited promising antitumor properties against colon HCT116 and breast T47D cell lines. 3D-Pharmacophore modeling and quantitative structure–activity relationship (QSAR) analysis were combined to explain the observed antitumor properties.
2-(5-Arylidene-4-oxo-3-phenyl-thiazolidin-2-ylidene)-3-oxo-propionitriles 4a-j 是通过芳香醛与 4-噻唑烷酮 3a, b 缩合制备的。后者是通过苯基异硫氰酸酯对 3-氧代丙腈 1a、b 的亲电攻击,然后在碱性条件下与氯乙酰氯反应得到的。此外,适当的仲胺和甲醛与 4-噻唑烷酮 3a 和 b 发生曼尼希反应,制备出 2-(5-杂环亚甲基)类似物 5a-h。合成的许多化合物对结肠 HCT116 和乳腺 T47D 细胞系具有良好的抗肿瘤特性。三维药层建模和定量结构-活性关系(QSAR)分析相结合,解释了观察到的抗肿瘤特性。
