  • Patent number: 8507221
    Abstract: The present invention discloses an improved process for the production of desired recombinant peptides from bacterial cells by using G-CSF as a novel fusion partner for their high level expression in these cells. The invention further provides an expression system comprising the fusion protein wherein the G-CSF is operatively linked to the peptide of interest via an enzymatic or chemical cleavage site which can be used to separate the fusion partner from the said peptide.

  • Patent number: 8383581
    Abstract: The present invention provides novel short-chain peptides, which primarily act as parathyroid hormone (PTH/PTH-1) receptor agonist. These short-chain peptides exhibit increased stability to proteolytic cleavage. Most of short-chain peptides were found to be stable in rat plasma up to 24 hours (in vitro), showed increased stability against GIT enzymes such as pepsin and acidic stomach pH and also against liver microsomes (in vitro). Due to increased metabolic stability, other than parenteral route of administration, some of the short-chain peptides can also be delivered by oral routes of administration, for the treatment/prevention of hypoparathyroidism and diseases characterized by bone mass reduction, such as osteoporosis, postmenopausal osteoporosis and for stimulating bone repair.

  • Publication number: 20120264685
    Abstract: The present invention provides novel short chain peptidomimetics, which act as GLP-1 receptors agonist and glucagon receptor antagonist. These dual acting peptidomimetics exhibit increased stability to proteolytic cleavage, especially against DPP-IV (Dipeptidyl peptidase-IV) enzyme, GIT enzymes such as pepsin and acidic stomach pH and also against liver microsomes (in vitro). Due to increased metabolic stability, other than parenteral route of administration, these short chain peptidomimetics can be delivered by oral routes of administration, for the treatment or prevention of diabetes and related metabolic disorders, such as obesity, hyperlipidemia and eating disorders.

  • Patent number: 4410923
    Abstract: Display apparatus is provided for a recording and/or playback device of the type having a movable record medium upon which cue signals may be recorded to indicate an end of "letter", an "instruction" or the like. A linear array of light indicating elements is selectively energized to provide a cursor indication of the present position of the record medium as it is moved relative to a reference position. Selected ones of these elements also are energized in response to the recording or playback of a cue signal to indicate the relative locations of the cue signals on the record medium. In one embodiment, a numerical display also is provided to indicate a time-related quantity of record medium which has been transported during a recording or playback operation. If the record medium is, for example, a magnetic tape transported from a supply reel to a take-up reel, motion pulses are generated as the tape is transported.
