Particularly, the present disclosure is directed to glycoenzyme inhibitor compound and compositions and methods of use thereof that can modulate the synthesis of globoseries glycosphingolipid SSEA-3/SSEA-4/GloboH in the biosynthetic pathway; particularly, the glycoenzyme inhibitors target the alpha-4GalT; beta-4GalNAcT-I; or beta-3GalT-V enzymes in the globoseries synthetic pathway. Additionally, the present disclosure is also directed to vaccines, antibodies, and/or immunogenic conjugate compositions targeting the SSEA-3/SSEA-4/GLOBO H associated epitopes (natural and modified) which elicit antibodies and/or binding fragment production useful for modulating the globoseries glycosphingolipid synthesis. Moreover, the present disclosure is also directed to the method of using the compositions described herein for the treatment or detection of hyperproliferative diseases and/or conditions. Furthermore, the instant disclosure also relates to cancer stem cell biomarkers for diagnostic and therapeutic uses.
专利号:US-10975069-B2 优先权日:2014-04-01 标 题 :Sigma-2 receptor ligand drug conjugates as antitumor compounds, methods of synthesis and uses thereof 发明人:HAWKINS WILLIAM; MACH ROBERT; SPITZER DIRK; VANGVERAVONG SUWANNA; VAN TINE BRIAN 权利人:UNIV WASHINGTON 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.
