  • HY-B1811
    Vasopressin 11000-17-2 99.83%
    Vasopressin is a cyclic nonapeptide that is synthesized centrally in the hypothalamus. Vasopressin participates in the hypothalamic-pituitary-adrenal axis, and regulates pituitary corticotropin secretion by potentiating the stimulatory effects of corticotropin releasing factor. Vasopressin also can act as a neurotransmitter, exerting its action by binding to specific G protein-coupled receptors.
  • HY-P0027
    Jasplakinolide 102396-24-7 ≥99.0%
    Jasplakinolide is a potent actin polymerization inducer and stabilizes pre-existing actin filaments. Jasplakinolide binds to F-actin competitively with phalloidin with a Kd of 15 nM. Jasplakinolide, a naturally occurring cyclic peptide from the marine sponge, has both fungicidal and anti-cancer activity.
  • HY-N10473
    Pulcherriminic acid 957-86-8 ≥98.0%
    Pulcherriminic acid is a cyclic dipeptide antimicrobial agent with high affinity for Fe3+, found mainly in Bacillus and yeast. Pulcherriminic acid chelates iron ions through a non-enzymatic reaction to form the extracellular red pigment pulcherrimin, which competes for iron nutrition and thus achieves an antibacterial effect. Pulcherriminic acid has great applications in food, agriculture and medical industries.
