标题 :Synthesis of histamine dihydrochloride
发明人：YEH WEN-LUNG; ANTCZAK CASIMIR; MCGOLRICK JEFFRY DAVID; ROTH MICHAEL JOSEPH; WRONA MARK
权利人:MAXIM PHARMACEUTICALS
摘要:The invention disclosed herein relates to the preparation of pharmaceutical grades of histamine dihydrochloride using a two step non-enzymatic synthetic method. The invention disclosed herein describes the synthesis of histamine dihydrochloride by the non-enzymatic decarboxylation of histidine and the step-wise conversion of the decarboxylated product to the dihydrochloride salt form. The invention disclosed herein considers a final product of histamine dihydrochloride containing less than each of the following: 0.8% L -histidine HCl monohydrate, 0.1% individual chromatographic impurities, and 2% total impurities, to be acceptable for pharmaceutical use.

标题:Facile synthesis of symmetric esters of alkylenebisphosphonic acids
发明人：HERLINGER ALBERT W; STEPINSKI DOMINIQUE C
权利人:UNIV LOYOLA CHICAGO
摘要:A facile synthesis of symmetric esters of C 1 -C 10 alkylenebisphopsphonic acids is disclosed in which a C 1 -C 10 alkylenebis(phosphonic dichloride) is reacted with an alcohol in the presence of a catalytic amount of 1H-tetrazole and a base in an aprotic solvent to form a first reaction mixture. The first reaction mixture is maintained for a time period sufficient to form a C 1 -C 10 alkylenebis(chloro ester phosphonate) that is reacted under basic conditions with an excess of a hydroxylated compound to form a second reaction mixture that is itself maintained for a time period sufficient to form a C 1 -C 10 alkylenebis(ester phosphonate) partial ester, homoleptic tetraester or mixed tetraester. The material so formed can be recovered or used as is.

标 题 :Modulation of globoseries glycosphingolipid synthesis and cancer biomarkers
发明人：WONG CHI-HUEY; HSU TSUI-LING; WU CHUNG-YI; CHEUNG SARAH K C; CHUANG PO-KAI
权利人:SINACA ACAD; WONG CHI-HUEY; HSU TSUI-LING
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 disgnostic and therapeutic uses.
