Isolation and Structure of Three Neuropeptides from the Corpora Cardiaca of the American Cockroach
In the last years numerous insect neuropeptides have been isolated and sequenced (Holman et al., 1988; Nachman et al., 1986a,b). Here the recent isolation of three new neuropeptides from the corpora cardiaca of the American cockroach, Periplaneta americana, is briefly summarized. These peptides are corazonin, a novel cardioacceleratory peptide, and two peptides related to the leucosulfakinins (Veenstra, 1989a,b).
