1. The molluscan neuropeptides FMRFamide, pQDPFLRFamide, and SCPB were tested on the isolated crop and penis of the terrestraial slug, Limax maximus. FMRFamide and pQDPFLRFamide stimulated the penis and inhibited contractions of the crop. In contrast, SCPB either stimulated or

To investigate the role of the N-terminal region of the heptapeptide FMRFamide-like peptide, pQDPFLRFamide, three analogues were synthesized. The analogues [pQNPFLRFamide, pQDAibFLRFamide (Aib = aminoisobutyric acid) and pQDGFLRFamide] contained modifications at amino acid residues 2 and 3, which we believed

The endogenous neuropeptides FMRFamide and FLRFamide (tetrapeptides) reversibly reduced a voltage-activated calcium current in the C1 neuron of Helix aspersa by an average of 20%. Two structurally related heptapeptides, pQDPFLRFamide and pQDPFLRIamide, both derived from another precursor protein in this

The C3 neurone, which acts as a motoneurone for the tentacle retractor muscle in Helix aspersa, contains both Phe-Met-Arg-Phe-NH2 (FMRFamide) and acetylcholine (ACh). Each of these transmitter substances evokes contraction of the isolated muscle. FMRFamide induces a delayed rise in
