Aims: To fetch pathways involved in targetting Hsp90 through Curcumin and Epigallocatechin
through Network pharmacological approach.
Background: Hsp90 is a molecular chaperone involved in stabilizing inflammatory protein which
may lead to chronic diseases. The herbal compounds Curcumin and Epigallocatechin processing antiinflammatory
properties are known to follow a common pathway and control the expression of Hsp90.
Objective: To collect the gene targets of Hsp90, Curcumin and Epigallocatechin in order to understand
protein-protein interactions of gene targets by constructing the interactome to identify the hub proteins.
Hub proteins docking was performed with curcumin and epigallocatechin. Finally, hub proteins
involvement with various human diseases were identified.
Methods: The gene targets of Hsp90, Curcumin and Epigallocatechin were obtained from there respective
databases. Protein-protein interactions of Pkcδ-Nrf2 and Tlr4 pathway gene targets were collected
from String database. Protein interaction network was constructed and merged to get intercession
network in cytoscape and Cluego was used to predict the disease related target genes. Docking of
ligands to target proteins was carried out using Autodock vina tool.
Result: The main key regulators of Curcumin and Epigallocatechin were identified particularly from
Pkcδ-Nrf2 and Tlr4 pathway.
Conclusion: The combined action of Curcumin and Epigallocatechin can reduce the expression of
Hsp90 eventually controlling the inflammation.
