Cinnamaldehyde is a natural product with broad spectrum of antibacterial activity. In this work, it was used as a template for design and synthesis of a series of 17 cinnamylideneacetophenones. Phenolic compounds 3 and 4 exhibited MIC (minimum inhibitory concentration) and MBC (minimum bactericidal concentration) values of 77.9 to 312 µM against Staphylococcus aureus, Streptococcus mutans, and Streptococcus
肉桂醛是一种具有广谱抗菌活性的天然产品。在这项工作中,它被用作设计和合成一系列17种肉桂亚甲基苯乙酮的模板。酚类化合物3和4对金黄色葡萄球菌,变形链球菌和血链球菌的MIC(最小抑菌浓度)和MBC(最小杀菌浓度)值为77.9至312 µM。化合物2、7、10和18对结核分枝杆菌表现出有效的作用(57.2 µM≤MIC≤70.9 µM)。B环上的取代基引起的亲水作用增强了对革兰氏阳性菌的抗菌活性。因此,通过使用高效液相色谱-光电二极管阵列检测(HPLC-PDA)分析来计算log Po / w,并且肉桂叉乙炔苯乙酮的值在2.5到4.1之间。此外,评估了3和4对肺细胞的作用,表明与阿霉素相比,它们具有中等毒性(46.3 µM≤IC50≤96.7 µM)。对生物活性化合物进行了计算机动力学的药物代谢动力学预测,并且没有违反Lipinski和Veber的规定,通过口服途径证实了其潜在的生物利用度。

A series of new (2E,4E)-1-(substitutedphenyl)-5-(substitutedphenyl)penta-2,4-dien-1-one derivatives were designed and synthesized. Compounds 3i, 3k were determined by X-ray. All of the compounds have been screened for their anti-inflammatory activity characterized by evaluating their inhibition against LPS-induced IL-6 and TNF-α release in cell RAW 264.7 stimulated with LPS. Compound 3i showed the

(E,E)-Cinnamylideneacetophenones 3a–j were epoxidized under mild conditions with Jacobsen's catalyst 4 and hydrogenperoxide or iodosylbenzene as oxidants. γ,δ-Monoepoxides and a diastereomeric mixture of α,β:γ,δ-diepoxides were obtained in each case, and only the α,β-monoepoxide of 4-nitrocinnamylideneacetophenone (3d) was isolated. The presence of a methyl group in the vinylic moiety of substrates

their telomerase inhibitory activity were tested. Among them, eight compounds showed good activity against cancer cells, among them compounds 56, 57 and 59 also showed low toxicity. Some of them showed excellent telomerase inhibitory activity with IC50 values ranging from 0.62 μM to 8.87 μM. Based on above, in depth structure-activity relationships were summarized, the compounds by replacing methyl group
