To find authentic PDB IDs for the proteins related to nonsmall cell lung cancer, you can use databases like the Protein Data Bank (PDB). Search for each protein's name or gene symbol in these databases to obtain their respective PDB IDs.

For selecting phytochemicals against those proteins in MOE software, consider literature review, and molecular docking studies. Identify phytochemicals with known anticancer properties and screen them using docking simulations to predict their binding affinity to your selected proteins. Additionally, consider the availability of experimental data supporting the effectiveness of these phytochemicals. Remember to validate your results, you must need to do molecular dynamics simulation for at least 100 ns, followed by MMPBSA or MMGBSA analysis.

@Zara You can select one or two standard drug with anticancer property and then after docking, you can compared all the docking energies of your selected ligands with the reference molecule.
