Wogonin, a natural product isolated from the plant Scutellaria baicalensis, has been shown to be a potent and selective inhibitor of CDK9. With the purpose of investigating the activity and selectivity of this chemical scaffold, several series of wogonin derivatives were prepared and screened for CDK9 inhibition and cellular antiproliferative activity. Among these compounds, the drug-like compound 51 showed potent activity against CDK9 (IC50 = 19.9 nM) and MV4-11 cell growth (IC50 = 20 nM). In addition, compound 51 showed much improved physicochemical properties, such as water solubility, compared with the parent compound wogonin. The follow-up studies showed that the compound 51 is selective toward CDK9-overexpressing cancer cells over normal cells. Preliminary mechanism studies on the anticancer effect indicated that 51 inhibited the proliferation of MV4-11 cells via caspase-dependent apoptosis. In addition, highlighted compound 51 showed significant antitumor activity in mouse acute myeloid leukemia (AML) models without producing apparent toxic effects in vivo, which gave us a new tool for further investigation of CDK9-targeted inhibitor as a potential antitumor drug especially for AML.

Phenotypic screening of high quality compound library is one of the most effective strategy to obtain novel bioactive compounds. Recently, our group have constructed a Wogonin-scaffold library with substituents diversity and successfully obtained a series

A novel series of 49 wogonin derivatives were synthesized by introducing group at 7-, 8- or B ring of wogonin. The cytotoxic activities against HepG2, A549 and BCG-823 cancer cell lines were also investigated in vitro. Several of them showed obvious cytotoxic activities and compound 3h possessed the highest potency against HepG2, A549, and BCG-823 with IC50 values of 1.07 μM, 1.74 μM and 0.98 μM, respectively. A quantitative structure-activity relationship (QSAR) study of these synthetic derivatives as well as wogonin indicated that high solubility and low octanol/water partition coefficient are favorable, and excessive electrostatic properties and refractivity are unfavorable for the cytotoxic activities of these wogonin derivatives. These findings and results provide a base for further investigations.
