Abstract: The invention relates to a derivative of a GLP-1 analogue of a general Formula I, which derivative comprises a side chain attached to a Lys residue at position 34, 35, 36, 37, or 38 of the GLP-1 analogue, which side chain comprises a Branched linker, a 1st and a 2nd Protractor selected from C18 diacid, C20 diacid, and sulfonic acid C16, and at least one Linker element-1 incorporating ethylene glycol units. Linker element-1 may be incorporated in an optional Pre-linker, and/or in a 1st or 2nd Post-linker. The invention also relates to novel GLP-1 analogues, novel side chain intermediate products and their manufacture and use to prepare derivatives of biologically active peptides and proteins, as well as pharmaceutical compositions and medical uses of the analogues and derivatives. The derivatives have very long half-lives while maintaining a satisfactory potency, which makes them potentially suitable for once-monthly administration.
Abstract: Described herein are peptide analogs of glucagon-like peptide 1 (GLP-1) that retain agonist activity, but are more resistant to proteolytic degradation than native GLP-1. In the analogs, at least one ?-amino acid found in the native GLP-1 is replaced with a ?-amino acid residue, which may or may not be cyclically constrained. Pharmaceutical compositions containing the analogs are described, as are methods to treat diabetes, and methods to make proteolytically resistant GLP-1 analogs.

Abstract: Novel activating receptors of the Ig super-family expressed on human myeloid cells, called TREM(s) (triggering receptor expressed on myeloid cells) are provided. Specifically, two (2) members of TREMs, TREM-1 and TREM-2 are disclosed. TREM-1 is a transmembrane glycoprotein expressed selectively on blood neutrophils and a subset of monocytes but not on lymphocytes and other cell types and is upregulated by bacterial and fungal products. Use of TREM-1 in treatment and diagnosis of various inflammatory diseases is also provided. TREM-2 is also a transmembrane glycoprotein expressed selectively on mast cells and peripheral dendritic cells (DCs) but not on granulocytes or monocytes. DC stimulation via TREM-2 leads to DC maturation and resistance to apoptosis, and induces strong upregulation of CCR7 and subsequent chemotaxis toward macrophage inflammatory protein 3-?. TREM-2 has utility in modulating host immune responses in various immune disorders, including autoimmune diseases and allergic disorders.
