A series of novel thiazolyl-pyrazoline derivativescontaining benzodioxole (C1–C20) have been designed and synthesized. Among of the synthesized compounds, 2-(5-(benzo[d][1,3]dioxol-5-yl)-3-(4-bromophenyl)-4,5-dihydro-1H-pyrazol-1-yl)-4-(4-bromophenyl)thiazole (C6) displayed the most potent inhibitory activity for HER-2 (IC50 = 0.18 μM for HER-2). Antiproliferative assay results indicated that compound
已经设计并合成了一系列含有苯并二恶唑(C1-C20)的新型噻唑基-吡唑啉衍生物。在合成的化合物中,2-(5-(苯并[ d ] [1,3]二恶酚-5-基)-3-(4-溴苯基)-4,5-二氢-1 H-吡唑-1-基)-4-(4-溴苯基)噻唑(C6)对HER-2表现出最强的抑制活性(HER-2的IC 50 = 0.18μM)。抗增殖试验结果表明,化合物C6在体外对MCF-7和B16-F10具有很高的抗增殖活性,IC 50值分别为0.09和0.12μM,与阳性对照厄洛替尼相当。进一步进行对接仿真以确定可能的结合模型。根据初步结果,在肿瘤生长中具有强抑制活性的化合物C6将是潜在的抗癌药。
Dihydropyrazole Derivatives Containing Benzo Oxygen Heterocycle and Sulfonamide Moieties Selectively and Potently Inhibit COX-2: Design, Synthesis, and Anti-Colon Cancer Activity Evaluation
Cyclooxygenase-2 (COX-2) as a rate-limiting metabolism enzyme of arachidonic acid has been found to be implicated in tumor occurrence, angiogenesis, metastasis as well as apoptosis inhibition, regarded as an attractive therapeutic target for cancer therapy. In our research, a series of dihydropyrazole derivatives containing benzo oxygen heterocycle and sulfonamide moieties were designed as highly potent
A series of novel aryl-2H-pyrazole derivatives bearing 1,4-benzodioxan or 1,3-benzodioxole moiety were designed as potential telomerase inhibitors to enhance the ability of aryl-2H-pyrazole derivatives to inhibit telomerase, a target of anticancer. The telomerase inhibition tests showed that compound 16A displayed the most potent inhibitory activity with IC50 value of 0.9 mu M for telomerase. The antiproliferative tests showed that compound 16A exhibited high activity against human gastric cancer cell SGC-7901 and human melanoma cell B16-F10 with IC50 values of 18.07 and 5.34 mu M, respectively. Docking simulation showed that compound 16A could bind well with the telomerase active site and act as telomerase inhibitor. 3D-QSAR model was also built to provide more pharmacophore understanding that could be used to design new agents with more potent telomerase inhibitory activity.

In continuance of our search for newer antihepatotoxic agents some novel pyrazoline derivatives containing 1,4-dioxane ring system were synthesized starting from 3-(2,3-dihydro-1,4-benzodioxane-6-yl)-1-substituted-phenylprop-2-en-1-one. Some of the synthesized compounds were evaluated for antihepatotoxic activity against CCl4-induced hepatotoxicity in rats. Among them some compounds have shown significant antihepatotoxic activity comparable to standard drug silymarin. (C) 2011 Elsevier Ltd. All rights reserved.
