Biological Activity

Isoginkgetin (Iso-ginkgetin, IsoG) is a chemical inhibitor of Pre-mRNA splicing, does not target the SF3b subunit of the U2 snRNP, inhibits splicing both in vivo and in vitro at micromolar concentrations.
Isoginkgetin appears to do so by preventing stable recruitment of the U4/U5/U6 tri-small nuclear ribonucleoprotein, resulting in accumulation of the prespliceosomal A complex.
Isoginkgetin inhibits cell proliferation in a reversible fashion, inhibits promoter-proximal transcription elongation.
