  • Title: Discovery of novel CDK1 inhibitors by combining pharmacophore modeling, QSAR analysis and in silico screening followed by in vitro bioassay.

    Abstract:
    Cyclin-dependent kinase 1 (CDK1) is a valid anticancer target. With this in mind we applied a modeling workflow by combining pharmacophore modeling and QSAR analysis followed by in silico screening towards the discovery of novel inhibitory CDK1 scaffolds. Virtual screening identified 10 low micromolar inhibitory leads: 8 from the National Caner Institute (NCI) list of compounds and 2 from our in house list of established drugs and agrochemicals. The most potent NCI hit illustrated anti-CDK1 IC(50) value of 0.83 microM, while the drug hit isoxsuprine illustrated anti-CDK1 IC(50) value of 2.9 microM and the agrochemical hit foramsulfuran showed IC(50) = 3.6 microM. These results demonstrate that our virtual screening protocol is able to identify novel anti-CDK1 leads for subsequent development into potential anticancer agents.
