  Eighteen novel flavonoid derivatives - substituted chalcones and flavones were synthesized and characterized by using NMR, IR, UV/Vis spectroscopy and elemental analysis. The target compounds were achieved by using a sequence of simple and effective reactions starting from phloroglucinol. The initial hydroxyl groups were protected by methylation and in the final flavones the 5-OH group was selectively

  合成了十八种新的类黄酮衍生物-取代的查耳酮和黄酮，并通过NMR，IR，UV / Vis光谱和元素分析对其进行了表征。通过使用一系列从间苯三酚开始的简单有效的反应，可以实现目标化合物。最初的羟基被甲基化保护，而在最后的黄酮中，5-OH通过AlBr 3选择性地脱甲基。5-甲氧基黄酮显示强荧光，在除去甲基后将其猝灭。

  The antiviral activity of natural phloroglucinols and of synthesized mono- and diacylphloroglucinols, and 2,6-diacyl-4,4-dialkylcyclohexa-1,3,5-triones was investigated. A correlation between the acyl chain length and inhibitory activity against vesicular stomatitis virus (VSV) was observed. Potent antiviral activity was found in di-isovalerylphoroglucinol. 2,6-Diacyl-4,4-dialkylcyclohexa-1,3,5-triones inhibited replication of the virus with low cytotoxicity.

  The rise in antibiotic resistance among pathogenic microorganisms has created an imbalance in the drugs available for treatment, in part due to the slow development of new antibiotics. Cystic fibrosis (CF) patients are highly susceptible to antibiotic-resistant pathogens, including methicillin-resistant Staphylococcus aureus (MRSA). Phloroglucinols and related polyketide natural products have demonstrated antimicrobial activity against a number of Gram-positive bacteria including S. aureus. In this study, we investigated a series of acylated phloroglucinol derivatives to determine their potential as lead compounds for the design of novel therapeutics. To assess the activity of these compounds, we determined the minimum inhibitory and bactericidal concentration (MIC and MBC, respectively), the minimum biofilm inhibitory and biofilm eradication concentration (MBIC and MBEC, respectively), and evaluated hemolytic activity, as well as their interaction with clinically relevant antibiotics. Of the 12 compounds tested against MRSA and methicillin-susceptible strains, four showed MIC values ranging from 0.125 to 8 µg ml−1 and all of them were bactericidal. However, none of the compounds were able to eradicate biofilms at the concentrations tested. Three of the four did not display hemolytic activity under the conditions tested. Further studies on the interactions of these compounds with clinically relevant antibiotics showed that phlorodipropanophenone displayed synergistic activity when paired with doxycycline. Our results suggest that these acylated phloroglucinols have potential for being further investigated as antibacterial leads.

  病原微生物中抗生素抗性的上升造成了治疗用药物的不平衡，这在一定程度上是由于新抗生素的研发缓慢。囊性纤维化(CF)患者极易感染抗生素抗性病原体，包括耐甲氧西林金黄色葡萄球菌(MRSA)。间苯三酚类及其相关多酮天然产物已显示出对多种革兰氏阳性细菌(包括金黄色葡萄球菌)的抗菌活性。在本研究中，我们调查了一系列酰化间苯三酚衍生物质，以确定它们作为新型治疗药物设计的先导化合物的潜力。为了评估这些化合物的活性，我们测定了最低抑制浓度和杀菌浓度(MIC和MBC)、最低生物膜抑制浓度和生物膜消除浓度(MBIC和MBEC)，并评估了溶血活性，以及它们与临床相关抗生素的相互作用。在针对MRSA和甲氧西林敏感菌株测试的12种化合物中，有4种的MIC值在0.125至8 µg/ml之间，且均为杀菌性。然而，在测试的浓度下，这些化合物均无法消除生物膜。其中3种在测试条件下未显示溶血活性。进一步研究这些化合物与临床相关抗生素的相互作用，结果显示，苯二丙酸苯酮在配伍强力霉素时表现出协同活性。我们的结果表明，这些酰化间苯三酚具有作为抗菌先导物进一步研究的潜力。

  Methicillin-resistant Staphylococcus aureus (MRSA) infections are well-known as a significant global health challenge. In this study, twenty-two congeners of the natural antibiotic rhodomyrtosone B (RDSB) were synthesized with the aim of specifically enhancing the structural diversity through modifying the pendant acyl moiety. The structure–activity relationship study against various MRSA strains revealed

  众所周知，耐甲氧西林金黄色葡萄球菌(MRSA) 感染是一项重大的全球健康挑战。在这项研究中，合成了天然抗生素红桃香酮 B (RDSB) 的 22 个同源物，目的是通过修饰侧酰基部分来特异性增强结构多样性。针对各种 MRSA 菌株的构效关系研究表明，间苯三酚支架中合适的疏水性酰基尾部是抗菌活性的先决条件。值得注意的是，RDSB 类似物11k被认为是一种有前途的先导化合物，对一组与医院死亡率相关的 MRSA 菌株具有显着的体外和体内抗菌活性。此外，化合物11k还具有其他强大的优点，包括抗菌谱广、杀菌作用快、以及优异的膜选择性。化合物11k在生物物理和形态水平上的作用模式研究表明， 11k通过膜超极化导致细胞裂解和膜破坏来发挥其MRSA杀菌作用。总的来说，所呈现的结果表明，新型改良 RDSB 类似物11k值得进一步探索，作为治疗 MRSA 感染的有希望的候选药物。
