Blasticidin S HCl is a natural product and an inhibitor of protein synthesis. Blasticidin S HCl is a broad-spectrum antibiotic that can inhibit the cell growth of prokaryotes, fungi, plants and mammalian cells.

Polymyxin B2, a significant component of polymyxin B, is an antibiotic cationic lipopeptide initially derived from B. polymyxa. This compound effectively inhibits P. aeruginosa, A. baumannii, K. pneumoniae, and E. cloacae strains, exhibiting minimum inhibitory concentrations (MICs) of 1-2, 0.5-1, 0.25-0.5, and 0.25-1 µg/ml, respectively. Notably, in a mouse model of P. aeruginosa bloodstream infection, administration of polymyxin B2 at a dosage of 4 mg/kg has been shown to decrease the number of colony-forming units (CFUs) in the blood.

Phytantriol is a fatty alcohol, and cubosomes containing Phytantriol have bactericidal effects on LPS deficient andpolymyxin-resistant A. baumannii strains.
