Metabolically activated heterocyclic N-oxide compounds for killing and visualizing hypoxic cancer cells
(University of Missouri--Columbia, 2009)
Tirapazamine (TPZ) is currently undergoing a variety of phase I, II, and III clinical trials for the treatment of various human cancers. TPZ derives its medicinal activity by inducing DNA damage in poorly oxygenated tumor ...
Investigations into the chemistry of protein tyrosine phosphatase redox regulation
(University of Missouri--Columbia, 2009)
Transmission of complex intracellular signals, such as those for glucose uptake or proliferation, is often accomplished through the reversible phosphorylation of specific protein tyrosine residues. This reversible ...
Inactivation of protein tyrosine phosphatases by endogenous and dietary agents
(University of Missouri--Columbia, 2009)
Protein tyrosine phosphatases are a class of enzymes that control a number of critical signaling pathways inside cells. We have discovered a number of dietary and endogenous agents that are capable of modifying these ...
Molecular basis of protein tyrosine phosphatase inhibition by biologically important small molecules with relevance to cell signaling pathways
(University of Missouri--Columbia, 2009)
Protein tyrosine phosphatase 1B (PTP1B) is an abundant mammalian enzyme and well known to be as a central player in the insulin and leptin signaling pathways. Peracetic acid is a strong oxidant molecule, endogenously ...
