Scientists from GLSynthesis (George Wright) and the Italian National Research Council (Andrea Lossani, Andrea Torti and Federico Focher) and San Matteo Hospital (Simona Gatti) in Pavia, Italy, present a poster entitled "Cloning and characterization of thymidine kinase and uridine-cytidine kinase from Entamoeba histolytica. Search for specific inhibitors." at the meeting of the Federazione Italiana Scienze della Vita, Riva del Garda, Italy, September 24-27, 2008.
March 2008. GLSynthesis and UMass Medical School present results of work on platelet antiaggregation activity of Ap4A and related compounds. Poster presented at American College of Cardiology Meeting, by H. Chang, I.B. Yanachkov, A.D. Michelson, G.E. Wright and A.L. Frelinger. "Diadenosine P1,P4-tetraphosphate and Its Tetraphosphonate Derivatives Synergistically Inhibit Platelet Activation via Both P2Y1 and P2Y12". Chicago, IL, March 29-April, 2008.
January 2008. GLSynthesis receives phase II small business grant from NIH to develop Fluorosome® active transport model. GLSynthesis has been awarded a 2 year phase II small business (SBIR) grant from the National Institute of General Medical Sciences (NIGMS), an institute of the National Institutes of Health (NIH) to continue development of a Fluorosome-based assay for p-glycoprotein. P-glycoprotein (pgp, MDR1) is the major mammalian drug transport protein found in cell membranes. It is responsible for efflux of many drugs from tissues, e.g. intestines and blood-brain barrier, and is a major source of antitumor drug resistance.
September 2007. GLSynthesis and Microbiotix present work on antibacterial prodrugs. Poster presented at International Congress on Antimicrobial Agents and Chemotherapy. G.E. Wright, S. Dvoskin, M. Yanachkova, W. Xu, I.B. Yanachkov, E. Dix, N.C. Brown, M.M. Butler, L. Kustigian and T. Bowlin, Prodrug Delivery of AU-FQ Antibacterial Compounds., Chicago, September 17-20, 2007.
June 2007. GLSynthesis establishes manufacturing plant in Zhianjiagang, near Shanghai, China. A full range of chemical product development, analysis and production is available at this plant. See Production Facilities for details.
