To design and synthesize a novel class of antitumor agents, featuring the 3, 5-substituted indolin-2-one framework.
Based on enzyme binding features of (Z)-SU5402, introducing a beta-pyrrole group at the 3-position of the indolin- 2-one core, a series of novel 3,5-substituted indolin-2-ones were designed and synthesized. Four human carcinoma cell lines of A-431, A-549, MDA-MB-468, and Autosomal Dominant Polycystic Kidney disease were chosen for the cell proliferation assay.
Twenty new compounds (1a-t) with E configuration have been designed, synthesized and bioassayed. Their structural features were determined by nuclear magnetic resonance (NMR) spectra, low- and high-resolution mass spectra, and confirmed by X-ray crystallography. Although the enzyme assay showed a weak inhibition effect against the epidermal growth factor receptor, vascular endothelial growth factor receptor, fibroblast growth factor receptor and platelet-derived growth factor receptor tyrosine kinases, the cell-based antitumor activity was promising. Compounds 1 g and 1 h showed higher inhibitory activity toward the A-549 and MDA-MB-468 cell lines with IC(50 ) of 0.065-9.4 micromol/L.
This study provides a new template for further development of potent antitumor drugs.
设计并合成一类新型抗肿瘤药物,其特征为具有3,5 - 二取代吲哚 - 2 - 酮骨架。
基于(Z)-SU5402的酶结合特征,在吲哚 - 2 - 酮核心结构的3位引入一个β - 吡咯基团,设计并合成了一系列新型3,5 - 二取代吲哚 - 2 - 酮。选择四种人类癌细胞系A - 431、A - 549、MDA - MB - 468和常染色体显性多囊肾病细胞系进行细胞增殖测定。
设计、合成并生物测定了20种具有E构型的新化合物(1a - t)。通过核磁共振(NMR)光谱、低分辨率和高分辨率质谱确定了它们的结构特征,并通过X射线晶体学得到证实。虽然酶活性测定显示对表皮生长因子受体、血管内皮生长因子受体、成纤维细胞生长因子受体和血小板衍生生长因子受体酪氨酸激酶的抑制作用较弱,但基于细胞的抗肿瘤活性很有前景。化合物1g和1h对A - 549和MDA - MB - 468细胞系显示出较高的抑制活性,IC(50)为0.065 - 9.4微摩尔/升。
本研究为进一步开发高效抗肿瘤药物提供了新的模板。
