| Peptide Function Description | Target site- Lipid Bilayer; Cationic cliotides display potent antibacterial activity against Gram-negative bacteria. It also possess prominent immunostimulating activity. Cationic cliotides are capable of secretion of various cytokines and chemokines in human monocytes at both resting and lipopolysaccharide-stimulated states. Hence also used as potential candidates for novel immunomodulating therapeutics. |

| Addtional Information | Synthesis Type: Ribosomal; Not active up to 100 µM- Staphylococcus aureus; Evidence for bacterial membrane disruption in E. coli. (Nguyen et al., 2016) Treatment with this cyclotide found to cause up-regulation of TNFa and IL-8 in THP-1 cells following LPS stimulation. (Nguyen et al., 2016); APD analysis reveals that the sequence of THE PEPTIDE shows 86.7% similarity to Cliotide T19. |
