标题:Scale up synthesis of silicasome nanocarriers

摘要:In order to facilitate the approval and commercialization of silicasome drug delivery systems (e.g. irinotecan silicasomes) it is necessary to scale up synthesis of the drug-loaded silicasomes. In this regard, it was discovered that the synthesis protocols used for laboratory synthesis of drug-loaded silicasomes (e.g., 500 mg/batch) do not scale to large scale silicasome production, because the resulting products were too heterogeneous for use as pharmaceuticals. Accordingly, new methods are provided herein that effectively afford the large-scale production of mesoporous silica nanoparticles (MSNPs) and lipid bilayer coated MSNPs (silicasomes).

摘要:An improved method for the chemical synthesis of glycosylated peptides has been developed. The method uses stereoselective glycan synthesis and chemical peptide ligation to produce glycopeptides at lower-cost and with higher efficiency/yield compared to conventional methods. In particular, a method for the large-scale, chemical synthesis of hydroxylated amino acid building blocks and glycosylated amino acids suitable for solid phase peptide synthesis (SPPS) are disclosed. SPPS-based methods using the glycosylated amino acids to chemically synthesize adiponectin-like peptides are also described. In vivo studies show that the adiponectin mimicking glycopeptides exhibit significant anticancer, anti-obesity and insulin sensitizing effects. Pharmaceutical compositions of the synthetic glycopeptides and methods of use thereof in treating diseases associated with deficient adiponectin are also described.

标题 :Identification of VSIG3/VISTA as a novel immune checkpoint and use thereof for immunotherapy

权利人:BIO TECHNE CORP
摘要:The ligand for VISTA is identified (VSIG3) as well as the use of this ligand and receptor interaction in the identification or synthesis of a VSIG3 agonist or antagonist compounds, preferably antibodies, polypeptides and fusion proteins which agonize or antagonize the effects of VSIG3 and/or VISTA and/or the VSIG3/VISTA interaction. These antagonists may be used to suppress VSIG3/VISTA's suppressive effects on T cell immunity, and more particularly used in the treatment of cancer, or infectious disease. These agonist compounds may be used to potentiate or enhance VSIG3/VISTA's suppressive effects on T cell immunity and thereby suppress T cell immunity, such as in the treatment of autoimmunity, allergy or inflammatory conditions. Screening assays for identifying these agonists and antagonist compounds are also provided.
