Checkpoint kinase 1 (Chk1), a member of the serine/threonine kinase family, is an attractive therapeutic target for anticancer combination therapy. A structure-based modeling approach complemented with shape components was pursued to develop a reliable pharmacophore model for ATP-competitive Chk1 inhibitors. Common chemical features of the pharmacophore(More)
An inclusion complex between chemosterilant quinestrol and 2,6-di-O-methyl-β-cyclodextrin (DM-β-CD) was prepared using the solution-ultrasonic method. A 1:1 stoichiometry was confirmed by elemental analysis. Analytical techniques such as UV-vis spectroscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, X-ray diffraction, and(More)
AIM Aromatase is an important target for drugs to treat hormone-dependent diseases, including breast cancer. The aim of this study was to develop a homogeneous time-resolved fluorescence (HTRF) aromatase assay suitable for high-throughput screening (HTS). METHODS A 384-well aromatase HTRF assay was established, and used to screen about 7000 compounds from(More)
Polo-like kinase 1, an important enzyme with diverse biological actions in cell mitosis, is a promising target for developing novel anticancer drugs. A combined molecular docking, structure-based pharmacophore modeling and three-dimensional quantitative structure-activity relationship (3D-QSAR) study was performed on a set of(More)
Polo-like kinase 1 is an important and attractive oncological target that plays a key role in mitosis and cytokinesis. A combined pharmacophore- and docking-based virtual screening was performed to identify novel polo-like kinase 1 inhibitors. A total of 34 hit compounds were selected and tested in vitro, and some compounds showed inhibition of polo-like(More)
