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.

Biochem/physiol Actions

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.

Other Notes

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