Comprehensive PubChem Download with Bioassay Info

Has anyone developed a PP protocol that downloads and curates Pubchem structures and biological assay information?

I realize that PubChem is large ( > 70 M structures).  Hence, I am hoping for a protocol that will perform this operation in

chunks.  Also, although I realize that one can download SDF and other ASCII files, I am looking for a protocol that extracts

information from PubChem in a more automated manner.

Thank you.
