  • Patent number: 11396531
    Abstract: The present disclosure relates to a peptide comprising at least five amino acid residues, wherein at least one amino acid residue is modified to an epsilon-lysine, delta-ornithine, gamma-2,4-diaminobutyric acid, beta-2,3-diaminopropionic acid, with the peptide also comprising at least one non-epsilon lysine, non-delta-ornithine, non-gamma-2,4-diaminobutyric acid or non-beta-2,3-diaminopropionic acid, and wherein the peptide displays a reduced or no cytotoxicity when compared to an equivalent non-modified peptide. In a preferred embodiment, the modifications are to the melittin or mastoparan B peptides, and comprise the substitution of at least one a-lysine residue for an ?-lysine residue, and the modified peptides display antimicrobial activity.
    Type: Grant
    Filed: October 31, 2017
    Date of Patent: July 26, 2022
    Assignees: Singapore Health Services Pte Ltd, Nanyang Technological University
    Inventors: Lakshminarayanan Rajamani, Venkatesh Mayandi, Tze Leng Eunice Goh, Roger Wilmer Beuerman, Navin Kumar Verma

  • Patent number: 7238527
    Abstract: The present disclosure relates to methods and compositions for in vitro cultivation of species of Swertia, e.g. Swertia chirata (Ham.). The disclosure provides culture media comprising Murashige and Skoog (MS) basal culture medium, plant hormones preferably selected from the group consisting of benzyladenine (BAP), gibberellic acid (GA3), and auxins, and other additives, e.g. sucrose and agar. Preferably, auxins are selected from the group consisting of indole acetic acid (IAA), indole butyric acid (IBA), and naphthalene acetic acid (NAA). Individual plant hormone concentrations are preferably from about 0.5 mg/L to about 5.0 mg/L.
