Kunitz-type peptides of the sea anemone Heteractis crispa: Potential anti-inflammatory compounds

Аннотация

Antihistamine activity of recombinant peptides, Kunitz-type serine protease inhibitors of the sea anemone Heteractis crispa, was studied. It was shown that the peptides rHCGS1.19 and rHCGS1.36 at a concentration 10 μM inhibit an increase in the calcium ion concentration in macrophages elicited by histamine at 62.2 and 84.0%, respectively. The anti-inflammatory effect can be seen as the result of mediated reactions between peptides and proteases involved in these processes, as with the histamine H₁-type receptor blocking.
