Publication number: 20220117893Abstract: A therapeutic agent for treating airways of a subject comprising one or more types or sizes of particles, each particle comprising in turn a biodegradable enclosure containing a mucolytic or another drug therein. A dispersing apparatus may be used to deliver metered doses of mucolytic and may be configured for self-administration by the subject. Encapsulation of the mucolytic in a liposomal formulation may prevent premature oxidation and maintain drug efficacy upon delivery to a target location in upper or lower respiratory tract.Type: ApplicationFiled: February 21, 2020Publication date: April 21, 2022Inventors: Dennis UNDERWOOD, Ashfaq MAHMOOD, Safia K. RIZVI

Patent number: 8747810Abstract: The present invention relates to compounds and related technetium and rhenium complexes thereof which are suitable for imaging or therapeutic treatment of tissues, organs, or tumors. In another embodiment, the invention relates to methods of imaging tissues, organs, or tumors using radiolabeled metal complexes, particularly tissues, organs, or tumors which express certain receptors to which the compounds or complexes of the invention have an affinity. The present invention also relates to methods of treating cancer, particularly those cancer lines which express certain receptors to which the compounds or complexes of the invention have an affinity. In yet another embodiment, the present invention provides methods of imaging and/or inhibiting receptors or neuroreceptors using compounds or complexes of the invention which have an affinity for the receptor or neuroreceptor to be imaged and/or inhibited.Type: GrantFiled: December 13, 2011Date of Patent: June 10, 2014Assignee: President and Fellows of Harvard CollegeInventors: Ashfaq Mahmood, Alun G. Jones, Naengnoi Limpa-Amara, Yijie Peng, Zeynep Akgun

Publication number: 20080226550Abstract: The present invention relates to compounds and related technetium and rhenium complexes thereof which are suitable for imaging or therapeutic treatment of tumors, e.g., carcinomas, melanomas and other tumors. In another embodiment, the invention relates to methods of imaging tumors using radiolabeled metal complexes. Preferred radiolabeled complexes for imaging tumors include technetium and rhenium complexes. The high tumor uptake and significant tumor/nontumor ratios of the technetium complexes of the invention indicate that such small technetium-99m-based molecular probes can be developed as in-vivo diagnostic agents for melanoma and its metastases. In yet another embodiment, the invention relates to methods of treatment of tumors using a radiolabeled metal complex as a radiopharmaceutical agent to treat the tumor.Type: ApplicationFiled: January 21, 2008Publication date: September 18, 2008Inventors: Ashfaq Mahmood, Matthias Friebe, Cristina Bolzati, Alun G. Jones, Alan Davison

Patent number: 7177822Abstract: A marketing system with a centralized database for compiling and distributing marketing data. The system compiles marketing data from a plurality of internal and external data sources into a centralized database. Internal and external sources include legacy systems. Data in the centralized database is distributed to a plurality of client venues by using an extract engine to extract a subset of data from the centralized database and creating a venue specific database. Access to the venue specific database is facilitated by use of a application programmers interface for allowing the development of applications for venue specific use of the venue specific database. Both the compilation and distribution process is performed on a periodic basis to provide timely, accurate, and consistent marketing data across the plurality of client venues.Type: GrantFiled: August 7, 2001Date of Patent: February 13, 2007Assignee: DaimlerChrysler CorporationInventors: Syed Ashfaq Mahmood, Susan I Stallard, Richard W Everett

Publication number: 20070009432Abstract: Radiopharmaceutical compounds are disclosed. A tropane compound is linked through the N atom at the 8-position to a chelating ligand capable of complexing technetium or rhenium to produce a neutral labeled complex that selectively binds to the dopamine transporter over the serotonin transporter with a ratio of 10 or more. These compounds can be prepared as separate diastereoisomers as well as a mixture of diastereoisomers. Also disclosed are radiopharmaceutical kits for preparing the labeled radiopharmaceutical compounds.Type: ApplicationFiled: September 8, 2006Publication date: January 11, 2007Applicants: President and Fellows of Harvard College, Organix, Inc., General Hospital Corporation, TheInventors: Peter Meltzer, Paul Blundell, Bertha Madras, Alan Fischman, Alun Jones, Ashfaq Mahmood
