标题:Scale up synthesis of silicasome nanocarriers
发明人：NEL ANDRE E; MENG HUAN; LIU XIANGSHENG

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:Tibolone in the treatment of complaints associated with the administration of drugs which prevent the synthesis of endogenous estrogen
发明人：KLOOSTERBOER HELENIUS J; BUNDRED NIGEL
摘要:Disclosed is a treatment of estrogen-deficiency related complaints in females that exhibit these complaints while they are on treatment with a drug which prevents the synthesis of endogenous estrogen. Such drugs are, e.g., anti-cancer drugs such as aromatase inhibitors. The invention resides in the use of tibolone, which has an unexpectedly beneficial working in this particular patient group in that it does not stimulate breast, while preventing bone loss and relieving climacteric complaints in a patient group in which this is more difficult than in any other group due to the nature of the concomitant cancer treatment (no circulating estrogen making for a higher severity of the complaints, the lack of effect on the estrogen receptor making for an increased risk associated with estrogenic breast stimulation once estrogen-like compounds are administered.

权利人:YANG DAVID J; YU DONGFANG; THOMPSON ANDREW S; CEIL POINT LLC; UNIV TEXAS
摘要:Novel methods of synthesis of chelator-targeting ligand conjugates, compositions comprising such conjugates, and therapeutic and diagnostic applications of such conjugates are disclosed. The compositions include chelator-targeting ligand conjugates optionally chelated to one or more metal ions. Methods of synthesizing these compositions in high purity are also presented. Also disclosed are methods of imaging, treating and diagnosing disease in a subject using these novel compositions, such as methods of imaging a tumor within a subject and methods of diagnosing myocardial ischemia.
