Patent number: 7470543Abstract: A method of identifying a ligand to a target molecule that includes: providing a reference compound that interacts with the target molecule; collecting a 1D 1H nuclear magnetic resonance spectrum of the reference compound in the presence of the target molecule; providing a plurality of test samples, each test sample including at least one test compound; collecting a 1D 1H nuclear magnetic resonance spectrum of the reference compound in the presence of each test sample and the target molecule; comparing the spectrum of the reference compound in the presence of the target molecule to the spectrum of the reference compound in the presence of each test sample and the target molecule to determine a change in one or more of the reference compound resonances; and identifying at least one test compound that interacts with the target molecule, wherein the test compound displaces the reference compound.Type: GrantFiled: June 5, 2003Date of Patent: December 30, 2008Assignee: Nerviano Medical Sciences S.r.l.Inventors: Claudio Dalvit, Brian J Stockman

Publication number: 20080233603Abstract: High-Throughput Screening (HTS) of large compound libraries is the method of drug-lead discovery. It is now well accepted that for a functional assay, quality is more important than quantity. A biochemical NMR method originally proposed by Percival and Withers (Biochemistry, 1992, 31, 498-505) is extended to the screening of Ser/Thr kinases. The method requires the presence of a CF3 (or CF) moiety on the substrate and utilizes 19F NMR spectroscopy for the detection of the starting and enzymatically modified substrates. Experiments can be performed in real time or in an endpoint assay format using protein and substrate concentrations comparable to the ones used by other HTS techniques. Application of this technique to the phosphorylation of a substrate by the protein Ser/Thr kinase AKT1 is presented.Type: ApplicationFiled: July 9, 2007Publication date: September 25, 2008Applicant: Pfizer Italia S.r.l.Inventors: Claudio Dalvit, Elena Ardini, Maria Magdalena Flocco, Gianpaolo Fogliatto, Nicola Mongelli, Marina Veronesi
