The methods are particularly advantageous as they overcome major issues typically observed in peptide chemical synthesis, including solubility and purity issues.
专利号:US-11649285-B2 优先权日:2016-08-03 标题 :Identification of VSIG3/VISTA as a novel immune checkpoint and use thereof for immunotherapy 发明人:KALABOKIS VASSILIOS; WANG JINGHUA; WU GUOPING; BAZAN JOSE FERNANDO; VALLEY CHRISTOPHER CARLIN 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.
专利号:US-5110929-A 优先权日:1986-08-07 标题 :Process for the preparation of N-alkylated quaternary nitrogen containing aromatic heterocycles 发明人:PARADIES HENRICH H 权利人:MEDICE CHAM PHARM FABRIK PUTTE 摘要:The synthesis of 4-, 4-(1,1)-and 3,5-substituted N-alkyl-pyridinium salts as well as of 2-carboxamide substituted N(1,4)diazinium compounds are described. The N-surfactants obtained have a small critical micelle concentration (CMC) of 10-5 -10-7 Mol/Liter. These surfactants produce micells of different size and form depending on the nature of the anions. 4-(1,1)-substituted and 3,5-substituted N-alkyl-pyridinium components are capable of forming vesicles in equeous solutions of different forms and sizes. The N-surfactants synthesized can be used as pharmaceuticals.

专利号:US-10370455-B2 优先权日:2014-12-05 标题 :Identification of VSIG8 as the putative VISTA receptor (V-R) and use thereof to produce VISTA/VSIG8 agonists and antagonists 发明人:MOLLOY MICHAEL; GUO YALIN; ROTHSTEIN JAY; ROSENZWEIG MICHAEL 权利人:IMMUNEXT INC 摘要:The receptor for VISTA is identified (VSIG8) as well as the use of this receptor in the identification or synthesis of agonist or antagonist compounds, preferably antibodies, polypeptides and fusion proteins which agonize or antagonize the effects of VSIG8 and/or VISTA and/or the VSIG8/VISTA binding interaction. These antagonists may be used to suppress 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 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.
