a new RNAP-targeting agent, which was assembled with high synthetic efficiency of 15 steps in the longest linear sequence. Dihydrostreptolydigin inhibited three representative bacterial RNAPs and displayed in vitro antibacterial activity against S. salivarius . The overall increase in synthetic efficiency combined with substantial antibacterial activity of this fully synthetic antibiotic demonstrates
细菌转录的抑制代表了一种有效且经临床验证的抗感染化疗策略。我们描述了针对细菌 RNA 聚合酶 (RNAP) 的链球菌属抗生素类方法的演变。这一努力导致了链球菌素、链球菌素、链球菌酸和一系列基于链球菌素的新型药物的合成和生物学评价。随后对 RNAP 抑制的生化评估表明,这类抗生素的活性需要链霉酸和特霉酸亚基的存在。此外,我们将 10,11-dihydrostreptolydigin 鉴定为一种新的 RNAP 靶向剂,它在最长的线性序列中以 15 个步骤的高合成效率组装。Dihydrostreptolydigin 抑制了三种代表性的细菌 RNAP,并显示出对唾液链球菌的体外抗菌活性。合成效率的整体提高与这种全合成抗生素的显着抗菌活性相结合,证明了有机合成在实现针对细菌转录的新化学试剂的设计和综合体外药理学评估方面的能力。
