a Synthetic route of mambalgin-1 and its mutants. b Synthetic mambalgin-1 inhibits recombinant human and chicken ASIC1a (hASIC1a and cASIC1a) channels in CHO cells. After two stable records of acid currents that were elicited by a pH drop from 7.4 to 6.0 for 4 s, synthetic mambalgin-1 was applied at pH 7.4 for 30 s followed by another application during a 4spH drop to 6.0. c Concentration–response curve showing the inhibition of hASIC1a and cASIC1a channels expressed in CHO cells (n = 3–14) by synthetic wild-type mambalgin-1
