Description

Description générale

A cell-permeable, naturally isolated Ginkgo biloba biflavanoid that acts as a general pre-mRNA splicing inhibitor (IC_max = 50 µM in splicing assays using HeLa nuclear extract) by blocking the spliceosome-meidated splicing process at the prespliceosome/A complex stage. Isoginkgetin treatment is shown to result in growth arrest in HEK293-derived cultures in a reversible manner without affecting cell viability (33 µM for 24 h).

A naturally isolated Ginkgo biloba biflavanoid that acts as a cell-permeable, reversible inhibitor against spliceosome-mediated pre-mRNA splicing (IC₅₀ and IC_max = 30 and 50 µM, respectively, in splicing assays using HeLa nuclear extract) by preventing the prespliceosome A complex from recruiting the U4/U5/U6 tri-snRNP (stable nuclear RNA and its associated proteins) to form B complex. Isoginkgetin treatment is shown to result in growth arrest in HEK293-derived cultures in a reversible manner without affecting cell viability (33 µM for 24 h).
