Recombinant proteins are routinely labeled with affinity tags, such as hexahistidine (6X-His), GST and FLAG, to facilitate both their detection and purification. 6X-His tags are often the tag of choice due to their small size, less potential to interfere in protein folding, weak immunogenicity, and high affinity for...

Ribonucleotide reductase, the rate-limiting enzyme for de novo DNA synthesis, is a common target for chemotherapy. Its increased activity in cancer cells is associated with malignant transformation and proliferation. Trimidox is a specific ribonucleotide reductase inhibitor that reduces levels of dGTP and dCTP in...

Protein tyrosine kinase (PTK) inhibitors are potential antiproliferative agents for diseases caused by the hyperactivity of PTK. Tyrphostins are a class of antiproliferative compounds which act as PTK blockers. PTK inhibitors which preferentially inhibit the epidermal growth factor receptor (EGFR) kinase and block...

Leukotriene B4 (LTB4) promotes a number of leukocyte functions including aggregation, stimulation of ion fluxes, superoxide anion production, chemotaxis, and chemokinesis. Two G protein-coupled receptors, BLT1 and BLT2 mediate the actions of LTB4. CAY10583 is a potent, selective full agonist for BLT2 with an EC50...
