cytotoxicities against cancercells, quantitative structure-activity relationships (QSAR) were calculated. Biological activities were determined by flow cytometry for cellcycle analysis and by immunoblot analysis for the detection of Aurorakinase A (AURKA) activity. Because 2-(2-Amino-6-(2,4-dimethoxyphenyl)pyrimidin-4-yl) phenol (derivative 12) selectively inhibited AURKA activity from the kinome assay
SOCl<sub>2</sub> catalyzed cyclization of chalcones: Synthesis and spectral studies of some bio-potent <sup>1</sup><i>H</i> pyrazoles
Some aryl-aryl 1H pyrazoles have been synthesised by cyclization of aryl chalcones and hydrazine hydrate in the presence of SOCl2. The yields of the pyrazoles are more than 85%. These pyrazoles are characterized by their physical constants and spectral data. The infrared, NMR spectral group frequencies of these pyrazolines have been correlated with Hammett substituent constants, F and R parameters. From the results of statistical analyses the effects of substituent on the spectral frequencies have been studied. The antimicrobial activities of all synthesised pyrazolines have been studied using Bauer-Kirby method.

need for novel antibiotics to help overcome what may be considered the greatest threat to modern medicine. Here we report the synthesis of fifteen novel 3,5-diaryl-1H- pyrazoles obtained via one-pot cyclic oxidation of a chalcone and hydrazine-monohydrate. The synthesised pyrazoles were then screened against Staphylococcus aureus and Escherichia coli to determine their antibacterial potential. The results
多重耐药细菌的出现增加了对新型抗生素的需求,以帮助克服可能被认为对现代医学的最大威胁。在这里,我们报告了通过查耳酮和肼一水合物的一锅循环氧化获得的十五种新型 3,5-二芳基-1H-吡唑的合成。然后针对金黄色葡萄球菌和大肠杆菌筛选合成的吡唑,以确定它们的抗菌潜力。结果表明,化合物7p在 MIC 8 µg/mL 时具有抑菌作用。该化合物对健康哺乳动物细胞 3T3-L1 无毒,最高测试浓度为 50 µg/mL。此外,化合物7p当处理高于 MIC 浓度时,显着影响枯草芽孢杆菌细胞裂解前的细菌形态发生。根据结果,确定了一种有前途的先导化合物,可用于未来的开发。
