As I understand it, pubmed (and medline) only index a subset of medical research, and excludes most non-medical science research. As Cutler was a chemist, I'm not sure any articles of his would be indexed by pubmed.

Scopus, which seems to be run by Elsevier, lists some abstracts and letters here (I have no idea how extensive this is) [1]
