  Design, synthesis and biological activities of sorafenib derivatives as antitumor agents

  摘要：

  A series of novel sorafenib derivatives, 9a-w, was designed and synthesized in high yields using various substituted anilines, and their antiproliferative activities against HCT116, PC-3 and MDA-MB-231 cell lines were also evaluated and described. All compounds exhibited potent antiproliferative activity against HCT116 and PC-3 cells with IC50 = 2.8-52.0 and 2.2-45.6 mu M; compounds 9p and 9q demonstrated competitive antiproliferative activities to sorafenib against all three cancer cell lines, the cytotoxicity of compound 9r is more potent than that of sorafenib. Compounds (9g, 9p, 9q and 9r) were chosen for further evaluation of the anti-angiogenesis activity, and showed the inhibition of sprout formation from aortic ring ex vivo. The structures of all the newly synthesized compounds were determined by H-1 NMR, C-13 NMR and HRMS. (C) 2012 Elsevier Ltd. All rights reserved.

  Thiourea and thioether derivatives of sorafenib: synthesis, crystal structure, and antiproliferative activity

  摘要：

  A series of novel sorafenib derivatives containing diaryl thiourea and thioether, 9a-u, was designed and synthesized, and their antiproliferative activities against HCT116 and MDA-MB-231 cell lines were also evaluated and described. Most compounds exhibited potent antiproliferative activity against HCT116 cells with IC50 = 1.8-80.4 mu M. Compounds 9p, 9r, and 9s demonstrated competitive antiproliferative activities to sorafenib, against all two cancer cell lines. The structures of all the newly synthesized compounds were determined by H-1 NMR, C-13 NMR, and HRMS, and compound 9n was characterized by single-crystal X-ray diffraction. Primary structure-activity relationships (SAR) have also been established.

  A series of 2-substituted-4-phenoxypyridine derivatives were designed, synthesized, and evaluated for their antiproliferative activity against 4 cancer cell lines (A549, HT-29, H460, and U87MG) in vitro. Most compounds showed moderate to excellent potency. Nine tyrosine kinases (c-Met, Flt-3, ALK, VEGFR-2, VEGFR-3, PDGFR-α, PDGFR-β, c-Kit, and EGFR) were used to evaluate the inhibitory activities with

  设计，合成了一系列2-取代的4-苯氧基吡啶衍生物，并在体外评估了它们对4种癌细胞系（A549，HT-29，H460和U87MG）的抗增殖活性。大多数化合物显示出中等至极好的效价。九种酪氨酸激酶（c-Met，Flt-3，ALK，VEGFR-2，VEGFR-3，PDGFR-α，PDGFR-β，c-Kit和EGFR）用于评估最有前途的类似物39的抑制活性。，显示Flt-3 / c-Met IC 50值为2.18 / 2.61 nM。构效关系研究表明，n-Pr作为R 1基团表现出更高的偏好性，而苯环上更强的单EWG（如R 2  = 4-F）则受益于其效价。
