专利号:US-2024209029-A1 优先权日:2021-04-21 标题:Adiponectin glycopeptides and compositions and methods of use thereof 发明人:WANG YU; LI XUECHEN; XU AIMIN; WU HONGXIANG; ZHANG YIWEI; LI YUANXIN 权利人:UNIV HONG KONG 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.

The resulting compounds are effective to modulate activity of arylhydrocarbon receptors, to inhibit activity of PCSK9, and to stimulate secretion of glucagon-like peptide 1 in mammals.

专利号:US-3992392-A 优先权日:1973-04-27 标题:Synthesis of indoles from anilines and intermediates therein 发明人:GASSMAN PAUL G 权利人:UNIV OHIO STATE RES FOUND 摘要:Preparing indoles and intermediates therefor by reacting an N-haloaniline with a β-carbonylic hydrocarbon sulfide to form an azasulfonium halide, reacting the azasulfonium halide with a strong base to form a thio-ether indole derivative, and then reducing the thio-ether indole, e.g. with Raney nickel, to form the indole compound. When an acetal or ketal of the β-carbonyl hydrocarbon sulfide is used, the azasulfonium salt is treated with a base, and then with an acid to form the thio-ether indole derivative. When an α-ethyl-β -carbonylic hydrocarbon sulfide is used, the resulting azosulfonium salt reacts with strong base to form a thio-ether indolenine derivative, which on reduction with Raney nickel or complex metal hydrides yields 3-substituted indoles. The aniline may be an aminopyridine to form an aza-indole compound in the process. The azasulfonium salts and thio-ether indole or thio-ether indolenine derivatives can be isolated and recovered from their respective reaction mixtures. The thio-ether-indole and thio-ether indolenine derivatives are useful as intermediates to make the indoles without the thio-ether group. The indoles are known compounds having a wide variety of uses, e.g., in making perfumes, dyes, amino acids, pharmaceuticals, agricultural chemicals and the like.
