Design, synthesis and antitumor activity of novel pyran-functionalized uracil derivatives: docking studies

Aim: Synthesis of novel pyran-based uracils that may have potent antitumor activity against hepatocellular carcinoma HepG2 and ovarian cancer SKOV3 cell lines. Materials & methods: Novel pyran-based uracils were synthesized and their anticancer activity was assessed using methyl thiazolyl tetrazolium and wound-healing assays to detect their cytotoxicity and their antiproliferative and antimigratory activities. Results: Compounds 3, 5, 6, 7, 8, 9, 10, 11 and 13 significantly inhibited cell proliferation of the HepG2 cell line. Compounds 7, 8, 9 and 13 significantly inhibited the proliferation of SKOV3 cells, which was also proven through docking studies with topoisomerase I. Conclusion: The molecular docking analysis revealed that 7 and 9 are two major compounds found to possess higher degrees of interaction with DNA gyrase.
