    摘要: This invention relates to relatively short peptides about 25-40 residues in length, which are naturally available in minute amounts in the venom of the cone snails or analogs to the naturally available peptides, and which include three cyclizing disulfide linkages and one or more &ggr;-carboxyglutamate residues. More specifically, the present invention is directed to &ggr;-conopeptides having the general formula I: Xaa1-Cys-Xaa2-Cys-Xaa3-Xaa4-Cys-Cys-Xaa5-Cys-Xaa6-Cys-Xaa7 (SEQ ID NO:1), as described herein; or having the general formula II: Xaa1-Cys-Xaa2-Cys-Xaa3-Xaa4-Cys-Cys-Xaa5-Xaa6-Cys-Xaa7-Cys-Xaa8 (SEQ ID NO:2), as defined herein; or having the general formula III: Xaa1-Cys-Xaa2-Cys-Xaa3-Xaa4-Xaa5-Cys-Cys-Ser-Asn-Ser-Cys-Asp-Xaa2-Cys-Xaa7 (SEQ ID NO:3), as described herein; or having the general formula IV: Xaa1-Cys-Xaa2-Cys-Xaa3-Xaa4-Xaa5-Cys-Cys-Ser-Asn-Ser-Cys-Asp-Xaa6-Cys-Xaa7 (SEQ ID NO:4), as described herein; or having the general formula V: Xaa1-Xaa2-Cys-Xaa3-Xaa4-Phe-Xaa5-Cys-Thr-Xaa6-Ser-Xaa7-Cys-Cys-Ser-Asn-Ser-Cys-Asp-Gln-Thr-Tyr-Cys-Xaa8-Leu-Xaa9 (SEQ ID NO:5), as described herein. The invention further relates to specific &ggr;-conopeptides, specific pro-&ggr;-conopeptides and nucleic acids encoding the pro-&ggr;-conopeptides. The invention also includes pharmaceutically acceptable salts of the conopeptides. These conopeptides are useful as agonists of neuronal pacemaker calcium channels.

    摘要: The present invention is directed to contryphan peptides having 6-12 amino acids, preferably including one or more D-tryptophan or D-leucine residues. The peptides of the present invention are generically termed "contryphans," although the D-leucine containing contryphans are sometimes referred to as leu-contryphans. More specifically, the present invention is directed to contryphan peptides having the general formula Xaa.sub.1 -Cys-Xaa.sub.2 -Xaa.sub.3 -Xaa.sub.4 -Pro-Xaa.sub.5 -Cys (SEQ ID NO:1), wherein Xaa.sub.1 is any amino acid or des-Xaa.sub.1, Xaa.sub.2 is Pro, 4-trans-hydroxyproline or Val, Xaa.sub.3 is D-Trp, L-Trp, D-Leu or L-Leu, preferably D-Trp or D-Leu, Xaa.sub.4 is any amino acid and Xaa.sub.5 is Trp or Tyr. When the peptide contains Xaa.sub.1, it is preferably Gly, Glu, or Lys, most preferably Gly. When Xaa.sub.3 is D- or L-Trp, Xaa.sub.2 is preferably Pro or 4-trans-hydroxyproline. When Xaa.sub.3 is D- or L-Leu, Xaa.sub.2 is preferably Val. The carboxy terminus may contain a carboxyl or an amide, preferably an amide. The present invention is further directed to the specific contryphan peptides and propeptides as described herein. The present invention is also directed to nucleic acids encoding the contryphan peptides and their propeptides as described herein. The contryphans of the present invention are useful as anticonvulsant or neuroprotective agents.

    摘要: The invention is directed to a new .mu.-conotoxin named GIIIA. .mu.-Conotoxin PIIIA consists of 22 amino residues and is found in the Eastern Pacific fish-hunting species Conus purpurascens. This conotoxin is a new Na.sup.+ channel blocker and can be used to resolve tetrodotoxin-sensitive sodium channels into three categories: 1) sensitive to .mu.-PIIIA and .mu.-conotoxin GIIIA; 2) sensitive to .mu.-PIIIA but not to .mu.-GIIIA; and 3) sensitive to neither of these two .mu.-conotoxins. In rat brain, binding competition studies between the two .mu.-conotoxins and saxitoxin suggest at least three pharmacologically distinguishable binding sites. Thus, .mu.-conotoxin PIIIA should be a key tool for distinguishing among different sodium channel subtypes.
