Patent number: 6613918Abstract: Ortho esters and ortho carbonates can be produced by alkylating esters and carbonates with, for example, the hexafluorophosphate salt of a trialkyl oxonium ion. The spiro species are useful intermediates in the synthesis of complex organic molecules. Synthetic pathways for the production of medically active compounds incorporates spiro ortho esters. Anti-first-pass effect materials are produced in high yield utilizing a synthetic strategy incorporating cyclic ortho ester intermediates.Type: GrantFiled: October 22, 2001Date of Patent: September 2, 2003Assignee: Bioavailability Systems, LLCInventors: Robert Seemayer, Jack Liang

Patent number: 6538022Abstract: This invention relates to determining the three-dimensional structure of the cytosolic domain of phospholamban (PLB) and its active site from NMR data of sufficiently high resolution for the three-dimensional structure determination. The invention also relates to methods for rational drug design enabling the design of phospholamban inhibitors based on using the three-dimensional structure data provided on computer readable media, as analyzed on a computer system having suitable computer algorithms. The invention also relates to phospholamban inhibiting compounds with certain structural, phsicochemical and spatial characteristics that allow for the interaction of said compounds with specific residues of phospholamban.Type: GrantFiled: February 18, 1999Date of Patent: March 25, 2003Assignee: Orion CorporationInventors: Piero Pollesello, Martti Ovaska, Jukka Tenhunen, Jukka Vidgren, Marjo Yliperttula-Ikonen, Carola Tilgmann, Timo Lotta, Juha Kaivola
