  We have previously identified the 7,8,9,10-tetrahydro-7,10-ethano-1,2,4-triazolo[3,4-a]phthalazine (1) as a potent partial agonist for the alpha(3) receptor subtype with 5-fold selectivity in binding affinity over alpha(1). This paper describes a detailed investigation of the substituents on this core structure at both the 3- and 6-positions. Despite evaluating a wide range of groups, the maximum selectivity

  nucleotide metabolism to promote apoptosis is a key principle of cancer therapy. Thymidylate synthase (TS) is a key rate-limiting enzyme in the initiation of DNA synthesis in cell. Here, we presented two types of thymidylate synthase inhibitors, and, the key pharmacological properties of these two types of thymidylate synthase inhibitor were extracted and combined to design new compounds with inhibitory activity

  抑制细胞核苷酸代谢以促进细胞凋亡是癌症治疗的关键原理。胸苷酸合酶（TS）是细胞DNA合成起始中的关键限速酶。在这里，我们介绍了两种类型的胸苷酸合酶抑制剂，并提取了这两种类型的胸苷酸合酶抑制剂的关键药理特性，并进行了组合，以设计出具有抑制活性的新化合物。因此，通过结合原理设计合成了具有共同生物促凋亡作用的42种新化合物。大多数化合物对A549，OVCAR-3，SGC7901和MDA-MB-231细胞具有良好的抗增殖活性。化合物10l对A549细胞的IC50为1.26μM，优于培美曲塞（PTX，IC50 = 3.31μM），此外，化合物10l的选择指数高于PTX。流式细胞仪分析表明，化合物10l（凋亡率为39.4％）可以诱导A549细胞凋亡，并有效抑制肿瘤细胞的增殖。进一步的蛋白质印迹分析表明，化合物10l可通过激活caspase-3，增加裂解的caspase-3的表达并降低bcl-2 / b

  A novel series of 5-(aroylhydrazinocarbonyl)escitalopram (58–84) have been designed, synthesized and tested for their inhibitory potential against cholinesterases. 3-Chlorobenzoyl- (71) was found to be the most potent compound of this series having IC50 1.80 ± 0.11 μM for acetylcholinesterase (AChE) inhibition. For the butyrylcholinesterase (BChE) inhibition, 2-bromobenzoyl- (76) was the most active

  Résumé Thirteen novel indole derivatives were efficiently synthesized through ultrasound irradiation by using 4-amino-5-(1H-indol-3-yl)-4H-[1,2,4]triazole-3-thiol (8) and 2-mercapto-5-substituted-1,3,4-oxadiazoles (5a–m). Compared with conventional and microwave methods, yields increased to 82–93%, and reaction times decreased to 15–35 min. The structures of these novel compounds were characterized by spectral data and elemental analysis. Two out of the synthesized compounds (10f and 10l) exhibited excellent activity against Staphylococcus aureus and Escherichia coli, and thus warrant further research.
