    摘要: The present invention relates to the use of &agr;-conotoxin peptides having the general formula Xaa1-Xaa2-Cys-Cys-Xaa3-Xaa4-Pro-Xaa5-Cys-Xaa6-Cys (SEQ ID NO: 1) for treating disorders regulated at neuronal nicotinic acetylcholine receptors. Such disorders include, but are not limited to, cardiovascular disorders, gastric motility disorders, urinary incontinence, nicotine addiction, mood disorders (such as bipolar disorder, unipolar depression, dysthymia and seasonal effective disorder) and small cell lung carcinoma, as well as the localization of small cell lung carcinoma. In this formula, Xaa1 is des-Xaa1, Tyr, mono-iodo-Tyr or di-iodo-Tyr, Xaa2 is any amino acid, Xaa3 is any amino acid, Xaa4 is any amino acid, Xaa5 is any amino acid and Xaa6 represents a peptide of 3-7 amino acids. Disulfide linkages exist between the first and third cysteines and the second and fourth cysteines. Pro may be replaced with hydroxy-Pro. The C-terminus may contain a hydroxyl or an amide group, preferably an amide group.

    摘要: This invention relates to relatively short peptides about 14-17 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 two cyclizing disulfide linkages. More specifically, the present invention is directed to conopeptides having the general formula: Gly-Cys-Cys-Ser-Tyr-Xaa.sub.1 -Xaa.sub.1 -Cys-Phe-Ala-Thr-Asn-Xaa.sub.2 -Xaa.sub.3 -Xaa.sub.4 -Cys (SEQ ID NO: 1), wherein Xaa.sub.1 is Pro or Hyp (trans-4-hydroxy-Pro), Xaa.sub.2 is Ser, Pro or Hyp, Xaa.sub.3 is Gly or Asp and Xaa.sub.4 is a Tyr or des- Xaa.sub.4. The disulfide bridges are between the first and third between the second fourth cysteine residues. The C-terminal end is preferably amidated. The invention further relates to the specific peptides AuIA: Gly-Cys-Cys-Ser-Tyr-Pro-Pro-Cys-Phe-Ala-Thr-Asn-Ser-Asp-Tyr-Cys (SEQ ID NO:2); AuIB: Gly-Cys-Cys-Ser-Tyr-Pro-Pro-Cys-Phe-Ala-Thr-Asn-Pro-Asp-Cys (SEQ ID NO:3); and AuIC: Gly-Cys-Cys-Ser-Tyr-Pro-Pro-Cys-Phe-Ala-Thr-Asn-Ser-Gly-Tyr-Cys (SEQ ID NO:4).

    摘要: Neuronal nicotinic acetylcholine receptors (nAChRs) are believed to mediate nicotine addiction. In addition, stimulation of nAChRs modulates release of neurotransmitters including dopamine, norepinephrine and serotonin. Thus, pharmacological manipulation of nicotinic receptors has implications for a wide variety of disorders including psychotic, mood, movement and cognitive. For most nAChRs, there are no subtype selective ligands. However, .alpha.-conotoxin MII, a small peptide from the carnivorous marine snail Conus magus, was recently isolated. This peptide has been shown to be a specific antagonist for .alpha.3.beta.2 nicotinic receptors. The peptide potently blocks part, but not all, of nicotine-stimulated dopamine release from rat brain striatal synaptosomes. In contrast it has no effect on potassium stimulated dopamine release. Other .alpha.-conotoxins specifically target distinct neuronal nAChR subtypes. .alpha.-Conotoxins thus represent new lead compounds for CNS disorders.

    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.
