I want to create a PDB file of a drug that is given in a paper. Can somebody share a tutorial or similar resources for a beginner-level user? Thank you.

1$\begingroup$ Could you add some context? What do you want the PDB file for? Do you have the structure of this molecule in another file format? (I didn't read the paper). $\endgroup$– marcinCommented Nov 2, 2022 at 19:58

$\begingroup$ yep have same question. Wouldn' t a cif file better serve the use if needed for fitting a ligand into electron density ? Or you just nred to depict molecule in 3D ? $\endgroup$– pippo1980Commented Nov 27, 2022 at 15:09

You can use Image2Smiles tool. It produces smi format, then you can convert smi to pdb using openbabel.
If you just have a few figures, I suggest using PubChem Sketcher.
or you could taket it from :
