synthesised a novel series of biphenyl-based inhibitors inspired by a published thiophene-based allosteric inhibitor. This series was evaluated in vitro against Escherichia coli DNAgyrase and E. coli topoisomeraseIV with the most potent compounds exhibiting IC50 values towards the low micromolar range for DNAgyrase and only ∼2-fold less active against topoisomeraseIV. The structure–activity relationships
据预测,到 2050 年,抗微生物药物耐药性将导致全球每年 1000 万人死亡,死亡人数超过癌症,使世界经济损失 100 万亿美元。显然,解决这个问题的策略是必不可少的,因为细菌进化正在使我们目前的抗生素失效。在已建立的抗菌靶 DNA 促旋酶上发现变构结合位点提供了一种新的药物化学策略。由于该位点与氟喹诺酮结合位点不同,因此尚未记录耐药性。使用计算机分子设计方法,我们设计并合成了一系列新的基于联苯的抑制剂,灵感来自已发表的基于噻吩的变构抑制剂。该系列在体外针对大肠杆菌DNA 促旋酶和大肠杆菌拓扑异构酶 IV 最有效的化合物在 DNA 促旋酶的低微摩尔范围内表现出 IC 50值,而对拓扑异构酶 IV 的活性仅低 2 倍。本文报道的结构-活性关系表明进一步利用这一变构位点的见解,提供了克服发展中的氟喹诺酮耐药性的途径。

and 4-substituted aryl boronic acids favored the (R)-enantiomer with most of the studied catalysts, meta-alkoxy substituted aryl boronic acids resulted in the (S)-enantiomer when used in combination with certain (R)-phosphoric acids. We propose that this selectivity reversal is the result of a lone pair-π interaction between the substrate ligated boronic acid and the phosphate. On the basis of this
