  • Publication number: 20220389059
    Abstract: The present invention is directed to a peptide for the delivery of anionic materials, such as anionic therapeutic agents, across a biological barrier, and methods of use thereof. The invention relates to a peptide comprising, or consisting of: X-(Xaa1)a-(Xaa2)b-Y-(Xaa3)c-(Xaa4)d-Z, in which each of X and Z is independently selected from Asn, Cys, Gln, Gly, Ser, Thr and Tyr; in which one of Xaa1 and Xaa2 is His and the other of Xaa1 and Xaa2 is Arg; in which one of Xaa3 and Xaa4 is His and the other of Xaa3 and Xaa4 is Arg; in which the amino functional group of X is, optionally, acylated; in which the carboxylate functional group of Z is, optionally, amidated; in which Y is selected from Ala and Trp; in which each of a and d is independently 2 to 4; and each of b and c is independently 2 to 4, or a salt or amide thereof.

  • Publication number: 20220347264
    Abstract: The inventors have determined that increasing the expression level or activity of FKBP-L polypeptide in a subject, which can be provided by expression of nucleic acids encoding FKBP-L or by providing FKBP-L polypeptides to a subject is advantageous for use in the treatment of obesity and obesity-related disorders. In particular increased expression or activity of FKBP-L polypeptide in a subject may be used to treat excessive weight gain (which can be characterised as obesity), glucose intolerance, diabetes and metabolic syndrome, which are closely linked to obesity and insulin resistance. FKBP-L can also be used as a biomarker for obesity and obesity-related disorders.

  • Patent number: 10500287
    Abstract: The present invention is directed to an amphipathic peptide and methods of using the amphipathic peptide for delivering small molecule agents to a cell. Ideally, the amphipathic cell penetrating peptide comprises less than approximately 50 amino acid residues with at least 6 arginine residues, at least 12 Alanine Residues, at least 6 leucine residues, optionally at least one cysteine residue, and at least two but no greater than three glutamic acids wherein the arginine residues are evenly distributed along the length of the peptide; and the peptide has a defined ratio of arginine to negatively charged amino acid residues and a defined ratio of hydrophilic amino acid residues to hydrophobic amino acid residues. The present invention is also directed to a nanoparticle and cell delivery system comprising the amphipathic cell penetrating peptide of the invention. The peptide, nanoparticle or cell delivery system of the invention may be used in therapy.

  • Patent number: 4574656
    Abstract: In a vehicle using a differential apparatus for enabling the operator to quickly stop a skid. A set of electric clutches is attached to the idler pinion gears of the differential and to the spider. A centrifugal switch attached to a pinion responds to rapid rotation of the pinion which occurs during skidding to engage the electric clutches which thereby stop the spinning of the vehicle wheels permitting the drive to regain control. A time delay device maintains the clutches engaged for a short time after the centrifugal switch reopens.
