(3 -Amino-6-thiophen-2-yl-thieno[2,3 -b]pyridin-2-yl)phenylmethanone (3) was discovered as a new type of cytotoxic agent selective against a tumorigenic cell line. The molecular structure of a previously reported compound, (4-hydroxy-3-methyl-6-phenylbenzofuran-2-yl)phenylmethanone (2), had remarkably similar bioisosteric substructures to that of compound 3. Although the relationship between the molecular structure and biological activity of each derivative synthesized from these two hit compounds (2 and 3) were studied, unexpectedly no correlation was observed. However, after further synthetic study from 3, one of the most potent derivative (10k) having a different SAR profile from 2, was discovered. (C) 2004 Elsevier Ltd. All rights reserved.
(3-氨基-6-噻吩-2-基-苯并呋喃[2,3-b]吡啶-2-基)苯甲酸甲酯(3)被发现是一种新型的选择性细胞毒性剂,对肿瘤生成的细胞系具有选择性毒性。先前报道的化合物(4-羟基-3-甲基-6-苯基苯并呋喃-2-基)苯甲酸甲酯(2)的分子结构与化合物3具有显著相似的生物电子等排体亚结构。尽管对这两种化合物(2和3)衍生出的衍生物的分子结构与生物活性之间的关系进行了研究,但意外的是并未观察到明显的相关性。然而,在对3进行进一步的合成研究后,发现了一种活性最强的衍生物(10k),其在活性结构关系研究中的性质与化合物2不同。 (C) 2004 Elsevier Ltd. 保留所有权利。
