hinokiflavone

Hinokiflavone, a novel modulator of pre-mRNA splicing activity both in vitro and in cellulo, inhibits the assembly of the spliceosome, particularly blocking the formation of the B complex. Additionally, it acts as a SUMO protease inhibitor by impeding the activity of sentrin-specific protease 1 (SENP1). Hinokiflavone also demonstrates significant cytotoxicity, including the inhibition of MMP-9.

2,3-Dihydrohinokiflavone is a suppressor of matrix metalloproteinases (MMP) gene expression and shows strong activity against Leishmania with an IC50 of 1.6 μM.
