标 题:Synthesis of rocaglamide natural products via photochemical generation of oxidopyrylium species
发明人：JONES II GUILFORD; GERARD BAUDOUIN; PORCO JR JOHN A
权利人:UNIV BOSTON
摘要:The present invention provides new strategies for the synthesis of compounds of the rocaglamide family and related natural products. In particular, the new biomimetic synthetic approach involves photochemical generation of an oxidopyrylium species from a 3-hydroxychromone derivative followed by 1,3-dipolar cycloaddition of the oxidopyrylium species to a dipolarophile. This approach can be used for the formation of adducts containing an aglain core structure. Methods for the conversion of aglain core structures to aglain, rocaglamide and forbaglin ring systems are also provided. The present invention also relates to the use of rocaglamide/aglain/forbaglin derivatives for the manufacture of medicaments for use in the treatment of cancer or cancerous conditions, disorders associated with cellular hyperproliferation, or NF-κB-dependent conditions.

摘要:Provided are use of galectin-1 (Gal-1) as an immune checkpoint in the preparation of a tumor immunotherapy medicament and the medicament, and provided is a new tumor immunotherapy strategy targeting the new immune checkpoint. Lactose and a derivative thereof can inhibit the immune checkpoint by competing Gal-1 on the surfaces of a cancer cell and an immune cell, and do not have significant toxic and side effects. Knocking out B4GATL1 to reduce protein galactosylation can significantly reduce the level of Gal-1 transferred from a tumor to a T cell, thereby enhancing the activation and function of the T cell. In addition, a lactose synthetase component LALBA is overexpressed in a mouse tumor, and de novo synthesis of lactose in a tumor microenvironment can be realized, such that an immune response mediated by a CD8+ T cell is enhanced. In combination with the anti-tumor effect and economic cost of lactose, a wide and feasible idea is provided for cancer treatment.

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.

摘要:Methods and compositions for treating cancers such as pancreatic cancer and synovial sarcoma are disclosed. Compounds comprising a sigma-2 receptor-binding moiety and a ferroptosis-inducing moiety are described, such as the methanesulfonate salt of a compound of structural Formula IV, n n, wherein n is an integer chosen from 1, 2, 3, 4, and 5, and R 2 is H or methyl. At least one described molecular species exhibits an IC 50 value below 5 μM against human pancreatic cancer cells in vitro. Administration of this species promoted shrinkage of pancreatic cancer tumors in a murine model system in vivo. It led to a 100% survival of experimental animals over a time course in which control therapies provided only 30% or 40% survival. Methods of synthesis of molecular species are also disclosed.
