Natural Product Identification
Common NameFK-506
DescriptionTacrolimus, also known as FK 506 or prograf, belongs to the class of organic compounds known as macrolide lactams. These are cyclic polyketides containing both a cyclic amide and a cyclic ester group. Thus, tacrolimus is considered to be a macrolide lipid molecule. A macrolide lactam containing a 23-membered lactone ring, originally isolated from the fermentation broth of a Japanese soil sample that contained the bacteria Streptomyces tsukubaensis. Tacrolimus is a drug which is used for use after allogenic organ transplant to reduce the activity of the patient's immune system and so the risk of organ rejection. It was given fda approval in 1994 for use in liver transplantation. Since then, this indication has expanded to kidney, heart, small bowel, pancreas, lung, trachea, skin, cornea, and limb transplants. It has also been used in a topical preparation in the treatment of severe atopic dermatitis. Tacrolimus is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Tacrolimus may be a unique E. Coli metabolite. FK-506 is found in Streptomyces clavuligerus, Streptomyces durmitorensis, Streptomyces hygroscopicus, Streptomyces kanamyceticus, Streptomyces tacrolimicus and Streptomyces tsukubensis. In humans, tacrolimus is involved in t cell receptor signaling pathway.
