In an effort to develop new antimicrobial agents, a series of chalconederivatives, 3-60, were prepared by Claisen-Schmidt condensation of appropriate acetophenones and 2-furyl methyl ketones with appropriate aromatic aldehydes, furfural, and thiophene-2-carbaldehyde in an aqueous solution of NaOH and EtOH at room temperature. The synthesized compounds were characterized by means of their IR- and NMR-spectral
Major anti-inflammatoryagents, steroids and cyclooxygenase, were proved to have serious side effects. Here, a series of chalconederivatives were synthesized and screened for anti-inflammatory activities. QSAR study revealed that the presence of electron-withdrawing groups in B-ring and electron-donating groups in A-ring of chalcones was important for inhibition of LPS-induced IL-6 expression. Further

respectively. In addition, the antibacterialactivity spectrum of 5f indicated action against planktonic cells of Enterococcus faecalis (MIC = 7.8 μg mL−1), Acinetobacter baumannii (MIC = 15.6 μg mL−1) and Mycobacterium tuberculosis (MIC = 5.7 μg mL−1). Altogether, these results open new avenues for 5f as an anti-Staphylococcus aureus agent, with potential applications as antibacterial drug, adjunct of antibiotics
金黄色葡萄球菌是现代最成功的病原体之一。作为皮肤和粘膜共生体的细菌可以在医疗保健和社区环境中传播并导致严重感染。因此,发现应对耐药菌株起作用的新型抗金黄色葡萄球菌化合物是一项巨大的挑战。在此,我们设计并合成了一系列 17 个查耳酮,在 A 环上被氨基取代,对甲氧西林敏感金黄色葡萄球菌(MSSA) 和耐甲氧西林金黄色葡萄球菌MRSA 浮游细胞进行了评估。根据Topliss的手动方法设计的B环上的取代基提高了抗菌效力。4-bromo-3'-aminochalcone ( 5f) 是最活跃的,表明对 MSSA 和 MRSA 的最小抑制浓度 (MIC) 值分别为 1.9 μg mL -1和 7.8 μg mL -1。的关联5F用万古霉素显示出对MSSA和MRSA的协同效应,与分别为0.4和0.3,部分抑制浓度指数(FICI)值。5f 的亚抑制浓度抑制 MSSA 和 MRSA 对人角质形成细胞的粘附。Chalcone
