Biochem/physiol Actions

Reversible: no

Product does not compete with ATP.

Primary Targetnuclear export of LR-NES

Cell permeable: yes

Target IC₅₀: ≤ 1 ng/ml for inhibiting proliferation and inducing cell cycle arrest at G1 phase

General description

A cell-permeable polyketide that displays potent anti-tumor properties in eukaryotes. Originally identified as a metabolite from the myxobacterium Sorangium cellulosum for its antibiotic activities against yeast and filamentous fungi. Ratjadones act by inhibiting nuclear export of LR-NES (leucine rich-nuclear export signal)-containing proteins by covalently binding to CRM1. Inhibits proliferation (IC₅₀ ≤1 ng/ml) and induces cell cycle arrest at the G1 phase.
