ceratotoxin a

Ceratotoxin A is a 29-residue peptide extracted from the accessory gland secretion fluid, known for its potent antibacterial properties.

Ceratotoxin A acetate is isolated from the accessory gland secretion fluid, with anti-bacterial effects.

Ceratotoxin-2 (CcoTx2) is a voltage-gated sodium channel inhibitor with half maximal inhibitory concentrations (IC50) of 8 nM for Na v 1.2 β 1 and 88 nM for Na v 1.3 β 1 [1].

Ceratotoxin-1 (CcoTx1) is a peptide toxin that functions as an inhibitor of various voltage-gated sodium channel subtypes. It selectively inhibits Nav1.1/β1, Nav1.2/β1, Nav1.4/β1, and Nav1.5/β1 with IC50 values of 523 nM, 3 nM, 888 nM, and 323 nM, respectively. Additionally, Ceratotoxin-1 is known to inhibit Nav1.8/β1 [1].

Ceratotoxins B, an antibacterial peptide, is produced by sexually mature females of Ceratitis capitata (medfly).
