Anti-Gram+ & Gram-, Antiviral, Antifungal, Antiparasitic, Spermicidal, Anti-HIV,

 
 

Additional info:

Active against S. aureus and E. coli (MIC 12 uM). The peptide is active against Leishmania major (Perez-Cordero JJ et al. 2011 Peptides in press). Also showed spermicidal activity. A segment corresponding to residue 1-18 was found to have a comparable activity to the parent peptide (JBC 1994; 269: 1934-39). Helix in TFE. This peptide could inhibit HIV infection at a concentration that is also toxic to T cells (J Virol 2005; 79:11598-11606). Ref updated 7/2016.
