Tachykinins are among the most widely-studied families of regulatory peptides characterized by a highly-conserved C-terminal -Phe-X-Gly-Leu-Met.amide motif, which also constitutes the essential bioactive core. The amphibian skin has proved to be a rich source of these peptides with physalaemin from the skin of Physalaemus fuscomaculatus representing the archetypal aromatic tachykinin (X=Tyr or Phe) and kassinin from the skin of Kassina senegalensis representing the archetypal aliphatic tachykinin in which X=Val or Ile. Despite the primary structures of both mature peptides having been known for at least 30 years, neither the structures nor organizations of their biosynthetic precursors have been reported. Here we report the structure and organization of the biosynthetic precursor of kassinin deduced from cDNA cloned from a skin secretion library. In addition, a second precursor cDNA encoding the novel kassinin analog (Thr(2), Ile(9))-kassinin was identified as was the predicted mature peptide in skin secretion. Both transcripts exhibited a high degree of nucleotide sequence similarity and of open-reading frame translated amino acid sequences of putative precursor proteins. The translated preprotachykinins each consisted of 80 amino acid residues encoding single copies of either kassinin or its site-substituted analog. Synthetic replicates of each kassinin were found to be active on rat urinary bladder smooth muscle at nanomolar concentrations. The structural organization of both preprotachykinins differs from that previously reported for those of Odorrana grahami skin indicating a spectrum of diversity akin to that established for amphibian skin preprobradykinins.

  • Thymopentin Acetate

    Thymopentin, also known as TP-5, is a synthetic derivative of thymopoietin, a thymic hormone, and has immunoregulatory properties. Thymopentin interacts with T cells, reduces endocrine and behavioral responses to experimental stress. It is also found to increase the number of cells undergoing apoptosis in irradiated cells and selectively bind to apoptotic cells.

  • Thymosin β4 Acetate

    Thymosin β4 is a 43 amino acid peptide which is regarded as the main intracellular G-actin sequestering peptide. Extracellular thymosin β4 may contribute to physiological processes such as angiogenesis, wound healing and regulation of inflammation.

  • GLP-1 (7-36) amide Acetate

    Glucagon-like peptide-1 (GLP-1) is an incretin derived from the transcription product of the proglucagon gene. The major source of GLP-1 in the body is the intestinal L cell that secretes GLP-1 as a gut hormone. Its physiological functions include promoting insulin sensitivity, decreasing food intake by increasing satiety in brain and increasing insulin secretion from the pancreas in a glucose-dependent manner.

  • Angiotensin II Acetate

    Angiotensin II is an octapeptide that produced from angiotensin I after the removal of two amino acids at the C-terminal by angiotensin-converting enzyme (ACE). Angiotensin II is mediated by AT1 and AT2 receptors, which are seven transmembrane glycoproteins with 30% sequence similarity.

  • Pramlintide

    Pramlintide is an analogue of amylin, a small peptide hormone that is released into the bloodstream by the β-cells of the pancreas along with insulin, after a meal. Like insulin, amylin is completely absent in individuals with Type I diabetes.

  • Aviptadil Acetate

    Aviptadil, also known as vasoactive intestinal polypeptide (VIP), is a 28 amino acid neuropeptide that belongs to the glucagon-growth hormone-releasing factor secretion superfamily. Aviptadil acts as a potent systemic vasodilator and bronchodilator. It inhibits the proliferation of vascular and bronchial smooth muscle cells and decreases platelet aggregation. These biological effects are mediated by specific VIP receptors.
