Post-transcriptional modifications of nascent mRNA include 5’ capping, splicing and 3’ end polyadenylation, resulting in the emergence of mature mRNA. Recent findings indicate that mRNA splicing inhibitors can be potential anti-cancer candidates. Soy-isoflavone fractions displayed an inhibitory effect of mRNA processing among a number of dietary components. Two major components of the isoflavone fraction, daidzin and genistin did not have an inhibitory activity against mRNA maturation. The aglycone form of them also failed to inhibit mRNA maturation. Instead, compounds with flavone skeleton inhibited the mRNA maturation in the nucleus. Considering that the structural difference between flavone and isoflavone compounds is that B-ring is attached either on the 2’ or 3’ position of C-ring, respectively, anti-mRNA maturation activity may require a defined structural basis. These data indicate that compounds with flavone skeleton specifically alter the mRNA processing step.
