Cadaside B is a novel calcium-dependent lipopeptide antibiotic, bearing multiple rare non-canonical amino acids and exhibiting potent antimicrobial activity towards multi-drug resistant Gram-positive pathogens. Synthetic studies towards cadaside B yielded a compound possessing the desired connectivity of macrocyclic scaffold, but poorly matching 1H NMR spectra and lack of bioactivity. Insights and
Cadaside B是一种新型的钙依赖性脂肽抗生素,具有多种稀有的非经典氨基酸,对多重耐药的革兰氏阳性病原体表现出强大的抗菌活性。对 cadaside B 的合成研究产生了一种化合物,该化合物具有所需的大环骨架连接性,但1 H NMR 光谱匹配不佳且缺乏生物活性。提出了对全合成的见解和挑战。
