  一类新型的微管蛋白聚合抑制剂通过有丝分裂灾难发挥有效的抗肿瘤活性

  摘要：

  在当前工作中，设计，合成和评估了一类新型的4,5-二氢-1 H-吡唑-1-羧酸酯衍生物（E01-E28）。其中，最有效的化合物E24表现出相当的活性针对癌细胞的面板（GI 50测距0.05-0.98  μ M）和微管蛋白聚合的抑制（IC 50  = 1.49  μ M）参照药物CA-4（P）（GI 50测距0.019-0.32  μ男，IC 50  = 2.18  μ M）。以下测定表明化合物E24干扰了微管蛋白灾难性事件和抢救的动力学，从而触发了G2 / M阻滞，导致ROS积累，PARP裂解和细胞凋亡。分子动力学模拟验证了化合物E24可以紧密结合到微管蛋白异源二聚体与β的Lys 254和β在对接姿势微管蛋白的Cys的241。还确定了代谢稳定性和药代动力学参数。半衰期（t 1/2）显示了三个微粒体中的物种差异。血浆消除半衰期（t 1/2），血浆峰值浓度（C max），平均保留时间（MRT），曲线下面积（AUC0

  A series of 16 chalcone compounds were synthesized by Claisen-Schmidt condensation of various aldehydes with acetophenone using KOH as a base in ethanol. The reaction affords the desired products in good yields. Then all the 16 compounds were converted into pyrazoles by treating with hydrazine hydrate in ethanol under reflux condition. Both chalcones and pyrazoles were screened for their in vitro antibacterial (Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa) and antifungal (Aspergillus flavus, Chrysosporium keratinophilum and Candida albicans) activity. Biological activities of these compounds were compared with those of commercially available antibiotic ampicillin and antifungal agent miconazole. Pyrazoles were found to be most active and effective than corresponding chalcones for antimicrobial activity. Out of the 7 pyrazole compounds tested for antibacterial and antifungal activity, 5 compounds, 4h, 4j, 4l, 4m and 4n are turned out to be potent antimicrobial agents. Therefore these derivatives could serve as a highly promising molecules for further development.

  通过克莱森-施密特冷凝反应，合成了一系列16种查尔酮化合物，使用不同的醛与乙酰苯酮在氢氧化钾的碱性条件下于乙醇中发生反应。反应获得期望产物，产率良好。随后，所有16种化合物通过在回流条件下用水合肼处理转化为吡唑。对查尔酮和吡唑进行了体外抗菌（大肠杆菌、金黄色葡萄球菌和铜绿假单胞菌）和抗真菌（青霉菌、角质毛霉和白色念珠菌）活性筛选。这些化合物的生物活性与市售抗生素氨苄青霉素和抗真菌剂米康唑进行了比较。研究发现，吡唑在抗微生物活性方面比对应的查尔酮更为活跃和有效。在测试的7种吡唑化合物中，4h、4j、4l、4m和4n五种化合物表现出很强的抗微生物活性。因此，这些衍生物有望成为进一步开发的极具潜力的分子。
