Synthesis and antibacterial activity of 2'-substituted chelocardin analogues.
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.
