  • Publication number: 20110245159
    Abstract: The present invention provides novel salts and solvates of macrocyclic compounds that bind to and/or are functional agonists of the ghrelin (growth hormone secretagogue) receptor. The invention also relates to polymorphs of these salts and solvates, pharmaceutical compositions containing these salts or solvates, and methods of using the pharmaceutical compositions. These pharmaceutical compositions are useful as therapeutics for a range of disease indications, in particular, for treatment and prevention of gastrointestinal disorders including, but not limited to, postoperative ileus, gastroparesis, including diabetic and postsurgical gastroparesis, opioid bowel dysfunction, chronic intestinal pseudo-obstruction, short bowel syndrome, functional gastrointestinal disorders and gastrointestinal dysmotility, such as that occurring in conjunction with other disease states, in critical care situations or as a result of treatment with pharmaceutical agents.

  • Patent number: 8022252
    Abstract: Novel spatially-defined macrocyclic compounds containing specific conformational control elements are disclosed. Libraries of these macrocycles are then used to select one or more macrocycle species that exhibit a specific interaction with a particular biological target. In particular, compounds according to the invention are disclosed as agonists or antagonists of a mammalian motilin receptor and a mammalian ghrelin receptor.

  • Publication number: 20110105389
    Abstract: The present invention provides novel conformationally-defined macrocyclic compounds that have been demonstrated to be selective modulators of the ghrelin receptor (GRLN, growth hormone secretagogue receptor, GHS-R1a and subtypes, isoforms and/or variants thereof). Methods of synthesizing the novel compounds are also described herein. These compounds are useful as antagonists or inverse agonists of the ghrelin receptor and as medicaments for treatment and prevention of a range of medical conditions including, but not limited to, metabolic and/or endocrine disorders, obesity and obesity-associated disorders, appetite or eating disorders, addictive disorders, cardiovascular disorders, gastrointestinal disorders, genetic disorders, hyperproliferative disorders, central nervous system disorders and inflammatory disorders.

  • Patent number: 6987909
    Abstract: An athermalized optical fiber component assembly including a limiting member, a mounting structure attached to the limiting member, a temperature compensating substrate attached to the mounting structure, and an optical fiber component mounted on the temperature compensating substrate. The movement of the temperature compensating substrate as a function of temperature is constrained by the limiting member. Also, a method for manufacturing an athermalized optical fiber component assembly.

  • Publication number: 20050135718
    Abstract: A bearing preload cage assembly for rotatably supporting an axially loaded shaft includes a bearing housing including stationary axially opposed supporting members, first and second axially spaced bearings, each including inner and outer races and rolling elements, first and second cylindrical cage segments coaxial with the shaft, each including a sleeve and circumferentially spaced axially protruding castellations, the outer races engageably received on an internal surface of their associated sleeve, the castellations of each cage segment proximate to and engageable with the outer race of the adjacent bearing, the supporting members proximate to and engageable with an adjacent cage segment, a resilient member biasing at least one of the outer races into full engagement with its rolling elements and, in turn, its rolling elements into full engagement with their inner race whereby the rolling elements of both bearings are maintained in full engagement with their inner and outer races continuously during shaft
