Chelocardin (1) was condensed with numerous hydrazines, hydrazides, and anilines, yielding 2'-substituted derivatives with antibacterial spectra similar to the parent antibiotic. The hydrazone derivatives 9 and 10 and the two anilino derivatives 42 and 44 had more in vivo antibacterial activity than chelocardin.
Chelocardin（1）与多种肼、酰肼和苯胺缩合，生成了2'-取代衍生物，其抗菌谱与母体抗生素相似。腙衍生物9和10以及两种苯胺衍生物42和44的体内抗菌活性比Chelocardin更高。
