The hydrophobic 20% ethanol fraction of tropical sea anemone Heteractis crispa was shown to contain at least 159 peptide compounds including neurotoxins, proteinase and α-amylase inhibitors, as well as modulators of acid-sensing ion channels (ASICs). The three new peptides, π-AnmTX Hcr 1b-2, -3, and -4 (41 aa) (short names Hcr 1b-2, -3, -4), identified by a combination of reversed-phase liquid chromatography and mass spectrometry were found to belong to the class 1b sea anemone neurotoxins. The amino acid sequences of these peptides were determined by Edman degradation and tandem mass spectrometry. The percent of identity of Hcr 1b-2, -3, and -4 with well-known ASIC3 inhibitors Hcr 1b-1 from H. crispa and APETx2 from Anthopleura elegantissima is 95-78% and 46-49%, respectively. Electrophysiological experiments on homomeric ASIC channels expressed in Xenopus laevis oocytes establish that these peptides are the first inhibitors of ASIC1a derived from sea anemone venom. The major peptide, Hcr 1b-2, inhibited both rASIC1a (IC50 4.8 ± 0.3 μM; nH 0.92 ± 0.05) and rASIC3 (IC50 15.9 ± 1.1 μM; nH 1.0 ± 0.05). The maximum inhibition at saturating peptide concentrations reached 64% and 81%, respectively. In the model of acid-induced muscle pain Hcr 1b-2 was also shown to exhibit an antihyperalgesic effect, significantly reducing of the pain threshold of experimental animals."xsd:string |
