Vanicoside B is a phenylpropanoyl sucrose derivative, can be isolated from the herb Persicaria dissitiflora. Vanicoside B targets cyclin-dependent kinase 8 (CDK8) and exhibits anti-tumor activity. The potential mechanism is Vanicoside B blocks CDK8-mediated signaling pathways and decreases the expression of epithelial-mesenchymal transition proteins, so that it leads to cell cycle arrest and apoptosis.

NVP-LCQ195 (LCQ-195) is an inhibitor of CDK1/2/3/5/9. NVP-LCQ195 induces cell cycle arrest and eventual apoptotic cell death of multiple myeloma (MM) cells. NVP-LCQ195 triggers decreased amplitude of transcriptional signatures related to oncogenesis, drug resistance and stem cell renewal in MM cell lines.
