Opis ogólny

A cell-permeable, naturally isolated Ginkgo biloba biflavanoid that acts as a general pre-mRNA splicing inhibitor (ICmax = 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 ICmax = 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).

Biflavonoids belong to a subclass of the plant flavonoid family. Distribution of biflavonoids in the plant kingdom is limited to several species. Previously, some pharmacological activities of biflavonoids were described such as inhibition of histamine release from mast cells and

Membrane-permeable compounds that reversibly inhibit a particular step in gene expression are highly useful tools for cell biological and biochemical/structural studies. In comparison with other gene expression steps where multiple small molecule effectors are available, very few compounds have been

Matrix metalloproteinase (MMP)-9 plays a key role in tumor invasion. Inhibitors of MMP-9 were screened from Metasequoia glyptostroboides (Dawn redwood) and one potent inhibitor, isoginkgetin, a biflavonoid, was identified. Noncytotoxic levels of isoginkgetin decreased MMP-9 production profoundly, but up-regulated the
