标题:Modulation of globoseries glycosphingolipid synthesis and cancer biomarkers
发明人:WONG CHI-HUEY; WU CHUNG-YI; CHEUNG SARAH K C; CHUANG PO-KAI; HSU TSUI-LING
权利人:ACADEMIA SINICA
摘要:The present disclosure relates to methods and compositions which can modulate the globoseries glycosphingolipid synthesis. 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.

标题:Process for the preparation of retro-inverso peptides and new intermediates thereof
发明人:PINORI MASSIMO; CENTINI FELICE; VERDINI ANTONIO S
权利人:SCLAVO SPA
摘要:A method of synthesis of a partially retro-inverso peptide incorporating at least one malonyl residue of formula (III) ##STR1## wherein R represents the side chain of an α-amino acid, is described which is characterized in that said malonyl residue is incorporated by condensing a 5-substituted-2,2-dimethyl-1,3-dioxane-4,6-dione of formula (IV) ##STR2## wherein R' is the side-chain R wherein the functional groups, if any, are suitably protected, with an amino acid, amino acid amide, peptide fragment, or pseudo-peptide fragment wherein the terminal carboxyl group, if present, and the possible side-chain functionalities are suitably protected and the reactive amino group is tri-alkyl-silylated. n The new compounds of formula (VI) and a process for the preparation of a partially retro-inverso tuftsin analog which involves use of said method and said intermediate are also described and claimed.

标题:Method and nucleic acid for the preparation of lecithin:cholesterol acyltransferase
发明人:BAER BRADFORD W; DRAYNA DENNIS T; LAWN RICHARD M; MCLEAN JOHN W
权利人:GENENTECH INC
摘要:Nucleic acid encoding lecithin:cholesterol acyltransferase is ligated into expression vectors and used to transform host cells for the synthesis of lecithin:cholesterol acyltransferase in recombinant cell culture. Lecithin:cholesterol acyltransferase amino acid sequence variants are described for enhancing the properties of lecithin:cholesterol acyltransferase. Lecithin:cholesterol acyltransferase and its variants are employed in the therapy of conditions characterized by hypercholesterolemia and for the mobilization of cholesterol in vivo.
