These mitogen-activated protein kinase substrates regulate many cellular processes associated with human diseases. In spite of this potential as a molecular target for chemotherapy, however, pharmacologically tractable inhibitors of mitogen-activated protein kinase phosphatase-1 have yet to be developed. Based on the results from a high-throughput screen for small molecule inhibitors of mitogen-activated protein kinase phosphatase-1, we designed, synthesized, and evaluated a focused library in an effort to further understand the structural requirements for mitogen-activated protein kinase phosphatase-1 inhibitory activity. © 2007 The Authors. date: 2007-01-01 type: Article type: PeerReviewed format: text/plain language: en rights: attached identifier: http://d-scholarship-dev.library.pitt.edu/22178/1/licence.txt identifier: Arnold, DM and Foster, C and Huryn, DM and Lazo, JS and Johnston, PA and Wipf, P (2007) Synthesis and biological activity of a focused library of mitogen-activated protein kinase phosphatase inhibitors.
