    Limited SAR study revealed that the hydroxy-substituted compound showed better ROS inhibition potential in case of 3-benzoyl and 3-ethylester coumarin derivatives. Whereas, chloro substitution was found to be important in case of 3-acetyl coumarin derivatives. Similarly, in case of sulfonate ester, chloro, and nitro groups especially at positions -4 and -3 of ring "R" played vital role in ROS inhibition

    Background: Infectious pathogenic bacteria are the key virulence in our daily life. Especially diseases produced by multidrug resistant Staphylococcus aureus (MRSA) still contributing in morbidity and mortality in humans. Discovery of new and safer antibiotics is an upmost task in current medicinal research. Methods: By keeping in mind the considerable antimicrobial activities of coumarin scaffold, 3-substituted coumarin derivatives 1-24 were synthesized by Knoevenegel condensation reaction. Different aryl aldehydes were treated with β-keto esters in the presence of organic base piperidine. All synthetic compounds were characterized by different spectroscopic techniques such as EI-MS, HREI-MS, 1H-NMR, and 13C-NMR. Compounds were screened to check for their in vitro anti- MRSA (multidrug resistant Staphylococcus aureus) activity against different strains of bacteria such as MRSA-252, EMRSA-16, EMRSA-17 and local clinical isolate. Micro-plate alamar blue assay (MABA) was used for this activity. Oxacillin, streptomycin, clindamycin and vancomycin were used as standards. Results: Results were reported as percent inhibition at 20 µg/mL concentration. Amongst all four standard drugs, only vancomycin was showed 19%, 24%, 21% and 40% inhibitions in case of MRSA-252, EMRSA-16, EMRSA-17 and local clinical isolate, respectively, at 20 µg/mL concentration. Most of the synthetic compounds were showed a weak to good inhibition as compared to standard, vancomycin. Conclusion: Newly identified compounds may serve as lead for future research in order to get the more powerful antibacterial agents.
    背景:传染性病原菌是我们日常生活中的主要致病菌。特别是由耐多药金黄色葡萄球菌(MRSA)引起的疾病仍然是人类发病和死亡的主要原因。发现新的、更安全的抗生素是当前药物研究的首要任务。 方法:考虑到香豆素支架具有相当高的抗菌活性,研究人员通过 Knoevenegel 缩合反应合成了 3-取代香豆素衍生物 1-24。 在有机碱哌啶存在下,不同的芳基醛与β-酮酯进行了处理。 所有合成化合物均通过不同的光谱技术(如 EI-MS、HREI-MS、1H-NMR 和 13C-NMR)进行了表征。对化合物进行了体外抗 MRSA(耐多药金黄色葡萄球菌)活性筛选,以检测其对不同菌株(如 MRSA-252、EMRSA-16、EMRSA-17 和本地临床分离菌株)的活性。该活性采用了微孔板金蓝分析法(MABA)。结果:结果以 20 µg/mL 浓度时的抑制百分率报告。在所有四种标准药物中,只有万古霉素在 20 µg/mL 浓度下对 MRSA-252、EMRSA-16、EMRSA-17 和本地临床分离物的抑制率分别为 19%、24%、21% 和 40%。 与标准药物万古霉素相比,大多数合成化合物的抑制率从弱到强。 结论:新发现的化合物可作为一种新的抗生素:新发现的化合物可作为未来研究的线索,以获得更强的抗菌剂。
