Amylin (20-29) (human) is the fragment of human islet amyloid polypeptide (hIAPP) or Amylin. Amylin is a 37-residue hormone. Amylin (20-29) (human) is responsible for the amyloidogenic propensities of the full length protein. Amylin (20-29) (human) can be transformed into its corresponding peptoid and retropeptoid sequences, to obtain beta-sheet breaker peptides as amyloid inhibitors.

Rhaponticin 6''-O-gallate showed inhibitory activity of NO production in lipopolysaccharide-activated macrophages, (IC50 = 11-69 microM).

Melanin Concentrating Hormone (MCH), a 19 amino acid cyclic peptide, is largely expressed in the hypothalamus. Melanin Concentrating Hormone is implicated in the control of general arousal and goal-orientated behaviours in mammals, and appears to be a key messenger in the regulation of food intake.
