一般描述

Ascomycin (FK520) is a macrolide and macrolactone antibiotic isolated from the soil bacterium, Streptomyces hygroscopicus var. ascomyceticus. Ascomycin is a C21 ethyl analog of the macrolide tacrolimus (FK-506). It is a 23-membered polyketide macrolide.
Chemical structure: macrolactam

生化/生理作用

Ascomycin is a strong immunosuppressant. It inhibits allogenic T-lymphocyte proliferation and can bind with high affinity to FKBP and inhibits calcineurin phosphatase in the nM range.
Ascomycin (FK520) possesses high anti-fungal and immunosuppressant activity. Ascomycin has been shown to inhibit the peptidyl-prolyl cis-trans isomerase activity of FK-506-binding proteins of T cells.

联系

An FK506 analog with an ethyl rather than an allyl group at position 21.

The immunosuppressive agent FK-506 has received much attention due to its efficacy and potency in the areas of transplant rejection and autoimmune disease. Calcineurin, a Ca(2+)-calmodulin activated phosphatase, was recently implicated in the immunosuppressive mechanism of FK-506. In our ongoing
