Germanicol induces selective growth inhibitory effects in human colon HCT-116 and HT29 cancer cells through induction of apoptosis, cell cycle arrest and inhibition of cell migration. Germanicol may have anti-inflammatory effects .
Bromamphenicol is a dibrominated derivative of the antibiotic chloramphenicol. It inhibits rat liver mitochondrial and E. coli protein synthesis by 90.6 and 98.8%, respectively, when used at a concentration of 93 μM, and inhibits DNA synthesis in human lymphoblastoid cells by 83% at 1 mM. Bromamphenicol can also bind to the major adhesin subunit DraE from E. coli.
Chloramphenicol acetate, an acetylated and inactive derivative of chloramphenicol, is synthesized in E. coli and S. aureus through the action of the inducible enzyme chloramphenicol acetyltransferase, utilizing acetyl coenzyme A (acetyl-CoA), to impart resistance to chloramphenicol. This compound exhibits no antibiotic activity against S. sonnei in turbidimetric assays.
