    Author: Balakrishnan N, Raj JS, Kandakatla N.
    Journal: Interdiscip Sci; 2016 Sep; 8(3):303-11. PubMed ID: 26298578.
    Abstract:
    Glycogen synthase kinase-3β (GSK-3β) is a kinase family enzyme and an emerged target for the treatment of various diseases. A total of 23 structurally diverse flavonoid inhibitors were used to generate pharmacophore models using HypoGen algorithm. The hypotheses Hypo1 was considered as a best model which consists of three features: one hydrophobic and two aromatic ring features. The Hypo1 pharmacophore model was employed as a query to screen NCI and natural compound databases to discover novel potential lead compounds. In addition, molecular docking studies were carried out with 596 compounds from screening studies. NSC230353, NSC66454, NSC159593, and NSC156759 from NCI database and STOCK1N-81808, ZINC02159818, ZINC04042470, and ZINC72326235 from natural compound database were identified as potential GSK-3β inhibitors.
