Fallaxidin-1.3 shows no antibacterial activity against Gram-positive or Gram-negative bacteria. Does not inhibit the formation of NO by neuronal nitric oxide synthase. Has no effect on splenocyte proliferation or smooth muscle contraction. Fallaxidin-3.2 shows antibacterial activity against the Gram-positive bacteria E.faecalis (MIC=100 uM) and L.lactis (MIC=500 uM). No antibacterial activity against the Gram-positive bacteria B.cereus, L.innocua, M.luteus, S.epidermidis, S.uberis and S.aureus, or the Gram-negative bacteria E.cloacae and E.coli. Expressed by the skin glands. The measured mass is that of Fallaxidin-3.2. The measured mass is that of Fallaxidin-2.1. Belongs to the frog skin active peptide (FSAP) family. Brevinin subfamily.
