Computational and Medicinal Chemistry
Shared Resource
Medicinal Chemistry Core Component was Established October 21st, 2013 with
support from the Walther Cancer Foundation.
Support of HTS, hit-2-lead follow-up (SAR) and scale-up for animal studies.
Long-term, this shared resource will expand to include non-cancer related projects
to support Purdue and CTSI faculty as a campus and CTSI resource.
