I looked on Fragalysis for the atoms commonly found in certain position in the protein and used the fragments listed (+0354 not listed) to build the submission. I tried not making it too flat, to flexible or too lipophilic
Although I have a master's in Organic Chemistry:Drug Discovery, I don't actually have any real-world experience of fragment-based drug design.
