Teixobactin is a potent antibiotic. Teixobactin shows antibacterial activity for gram-negative bacteria. Teixobactin inhibits cell wall synthesis by binding to a highly conserved motif of lipid II and lipid III[1][2][3]. | [Definition]
ChEBI: Teixobactin is a cyclodepsipeptide that is isolated from the previously unculturable bacterial species Eleftheria terrae and is active against gram-positive bacteria. It has a role as an antibacterial agent. It is a peptide antibiotic, a cyclodepsipeptide and a macrocycle. | [in vivo]
Teixobactin (1-20 mg/kg; i.v.; once) shows antibacterial activity in mice[3]. | Animal Model: | Female CD-1 mice (MRSA ATCC33591)[3] | | Dosage: | 1, 2.5, 5, 10, 20 mg/kg | | Administration: | i.v.; once; one hour post-infection | | Result: | Showed good antibacterial activity and all treated animals survived. |
