The tested cells remained intact, suggesting wogonoside had no inhibitory activity on HCC cells. 3.two. Baicalein Prevents HCC Cells from Forming Colonies. To study the anti-HCC effect of baicalein, we carried out colony forming assay to observe if baicalein interferes using the capability of single cell to form developing colony, which represents an essential character of cancer cells’ ability to attach, survive, and proliferate. As shown in Figure 2(a), baicalein Phospholipase A Inhibitor Purity & Documentation therapy dose-dependently suppressed the formation of HCC cell colonies in both SMMC-7721 and Bel-7402 cells. Comparable to the benefits of cell viability assay, baicalin exhibited only a weak activity at higher doses against Bel-7402 cells. Measurements of colony quantity and colony size indicated that baicalein reduced both the quantity and size of colonies in a dosedependent manner. Interestingly, baicalin showed inhibition of foci size of Bel-7402 without the need of an obvious decline of colony quantity whilst its activity against SMMC-7721 cell colony formation remained minimal (Figures 2(b) and 2(c)). three.3. Baicalein Induces Apoptosis in HCC Cells. We subsequent investigated the type of cell death underlying the inhibition of HCC cells mediated by baicalein. Following the remedy of baicalein, the look of HCC cells considerably changed.3. Results3.1. Baicalein Inhibits Proliferation of HCC Cells within Water-Soluble Concentrations. We firstly undertook a study to preliminarily evaluate anti-HCC effects of four big flavonoids, baicalein, baicalin, wogonin, and wogonoside, from Scutellaria baicalensis Georgi. The structures of your compounds are shown in Figure 1(a). Two human HCC cell lines, SMMC-7721 and Bel-7402, were utilized for screening. The concentrations causing 50 inhibition of cell viability (IC50 s) were listed in Table 1. Immediately after 24 h remedy, both baicalein and wogonin triggered significant proliferation inhibition on HCC cells. In contrast, baicalin showed tiny activity against HCC cells with calculated IC50 s markedly larger than baicalein in both cells.
