Trofinetide, sold under the brand name Daybue, is a medication used for the treatment of Rett syndrome. It is taken by mouth.

chemical compound

'''N-Formylmethionyl-leucyl-phenylalanine (fMLF, fMLP or N-formyl-met-leu-phe') is an N''-formylated tripeptide and sometimes simply referred to as chemotactic peptide is a potent polymorphonuclear leukocyte (PMN) chemotactic factor and is also a macrophage activator.

Alazopeptin is an antibiotic, with moderate anti-trypanosomal and antitumor activity. It was originally isolated from Streptacidiphilus griseoplanus, sourced from soil near Williamsburg, Iowa. It is also isolated from Kitasatospora azatica It is still largely produced via fermentation broths of that organism. Structurally, alazopeptin is a tripeptide and contains 2 molecules of 6-diazo-5-oxo-L-norleucine and one molecule of L-alanine. In 2021 the biosynthetic pathway of alazopeptin was elucidated.

chemical compound

Leupeptin, also known as '''N-acetyl-L-leucyl-L-leucyl-L-argininal''', is a naturally occurring protease inhibitor that can inhibit cysteine, serine and threonine peptidases.

Pyroglutamyl-histidyl-glycine (pEHG) is an endogenous tripeptide that acts as a tissue-specific antimitotic and selectively inhibits the proliferation of colon epithelial cells. Early research indicated that pEHG had anorectic effects in mice and was possibly involved in the pathophysiology of anorexia nervosa. However, subsequent studies have found that pEHG lacks anorectic effects and does not alter food intake in mice.
