Publication number: 20120022016Abstract: The present invention relates to pharmaceutical compositions containing tumor-selective targeted inhibitor glycoconjugates. These bioconjugates are ALK5 inhibitors covalently bound to biocompatible carrier molecules which selectively target and specifically bind to Muc4 that is overexpressed on a variety of tumor cell types. The ALK5 inhibitors are conjugated to tumor targetable glycans through a covalent linker. Preferably the acid-labile linker is designed to be stable in plasma and releases pharmacologically active inhibitors through acid-catalyzed hydrolysis in the acidic environment of the target tumor where the inhibitor activity is restored. Because the glycoconjugates are stable at physiological pH and in plasma, they advantageously reduce undesirable systemic ALK5 inhibitor activity; however, the preferable glycoconjugates are acid-labile conjugates that can be hydrolyzed upon reaching the more acid environment of the tumor.Type: ApplicationFiled: July 18, 2011Publication date: January 26, 2012Inventor: Donald L.

Publication number: 20100249386Abstract: The present invention relates to the field of organic chemistry and in particular to organic free radicals used as polarizing agents in the technique of Dynamic Nuclear Polarization (DNP), which involves transferring the polarization of electron spins to the nuclei of a compound whose Nuclear Magnetic Resonance (NMR) is being observed. It concerns dinitroxide-type biradical polarizing agents characterized by a rigid linkage between the nitroxide units that enables optimal orientation and distance to be maintained between the aminoxyl groups of said nitroxide units. This particular structure enables, at low temperatures and high fields, optimal transfer of polarization and optimal enhancement of NMR/MAS signals of the polarized nuclei of the compound studied.Type: ApplicationFiled: May 29, 2009Publication date: September 30, 2010Applicants: UNIVERSITE DE PROVENCE, MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Olivier OUARI, Hakim KAROUI, Francois Le MOIGNE, Paul TORDO, Robert G.
