Core Tip

Core tip: In this study we inform about our first results obtained from cell proliferation assays, flow cytometry analysis and Western blot analysis of HCT116 cells after treatment with compound K-453, which belongs to a group of synthetic derivatives of indole phytoalexins originally isolated from cruciferous vegetables. This study demonstrates that our compound induces the mitochondrial pathway of apoptosis and that the antiproliferative effect of our substance may be linked to inhibition of several signaling pathways. Our results provide a rationale for further in vivo anticancer efficacy studies.
