Ann Clin Lab Res. 2016, 4:4 doi: 10.21767/2386-5180.10001332386-5180http://10.2.3.109/handle/32116/427Chemokines are a family of small chemotactic cytokines, which play a significant role in lymphocyte homing to secondary lymphoid organs in addition to tumor growth and metastasis. Thus, inhibition of chemokine receptor caught attention for anticancer treatment strategy. We studied molecular docking of chemokines receptor CXCR2, CXCR4, and CCR5 against natural and marine compounds. All selected natural and marine compounds were docked with the X-ray crystal structure of CXCR2, CXCR4, and CCR5 retrieved from the PDB by using Maestro 9.6. Molecular docking was executed by the XP (extra precision) mode of GLIDE. On the basis of Gscore and protein-ligand interactions, top-ranking compounds were outlined. The docking study carried out to summarize the various Gscore, hydrophobic, electrostatic bond, hydrogen bond, π-cation and π-π interactions and oversee the protein-ligand interactions. Moreover, effect of Epigallocatechin-3-gallate (EGCG) on biological activity such as mRNA expression (CXCR2, CCR5, and Bid), cell proliferation, ROS, and cell-migration was reported after the 48 hrs treatments in MCF-7 cells. The RT-PCR densitometric bands analysis showed that compound EGCG reduced the mRNA expression of CXCR2, CCR5 and increased the Bid at 40 μM and 80 μM concentration. Moreover, EGCG significantly reduced cell proliferation, ROS generation and cell-migration after 48 hours treatments.enCancerChemokinesNatural and marine compoundsMaestro 9.6Molecular dockingIn vitroArticle
