标题:一种戊柔比星合成方法
摘要:本发明公开了一种戊柔比星合成方法,盐酸柔红霉素在原甲酸三乙酯对其羰基进行保护下,进行溴代反应,反应液经过浓缩处理,直接进入脱保护反应,脱保护反应结束后,即以盐析的方式将溴化物中间体结晶出来,结晶出来的溴化物中间体先与正戊酸钾反应,再与三氟醋酸酐反应成酰胺制得戊柔比星.本发明反应条件温和,反应时间较短,易于操作控制,适合大规模工业生产.

标题:Scale up synthesis of silicasome nanocarriers

摘要:In order to facilitate the approval and commercialization of silicasome drug delivery systems (e.g. irinotecan silicasomes) it is necessary to scale up synthesis of the drug-loaded silicasomes. In this regard, it was discovered that the synthesis protocols used for laboratory synthesis of drug-loaded silicasomes (e.g., 500 mg/batch) do not scale to large scale silicasome production, because the resulting products were too heterogeneous for use as pharmaceuticals. Accordingly, new methods are provided herein that effectively afford the large-scale production of mesoporous silica nanoparticles (MSNPs) and lipid bilayer coated MSNPs (silicasomes).

摘要:The present invention relates to novel methods of synthesis of therapeutic and diagnostic dendrimers. In particular, the present invention is directed to novel dendrimer conjugates, novel methods of synthesizing the same, compositions comprising the conjugates, as well as systems and methods utilizing the conjugates (e.g., in diagnostic and/or therapeutic settings (e.g., for the delivery of therapeutics, imaging, and/or targeting agents (e.g., in disease (e.g., cancer, inflammatory disease) diagnosis and/or therapy, pain therapy, etc.)). Accordingly, dendrimer conjugates of the present invention may further comprise at least two different components for targeting, imaging, sensing, and/or providing a therapeutic or diagnostic material and/or monitoring response to therapy. Furthermore, the novel synthesis methods of certain embodiments of the present invention provide significant advantages with regard to total reaction time and simplicity.

标 题:Use of galectin-1 as immune checkpoint in preparation of tumor immunotherapy medicament and medicament

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: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.
