US Patent:
2005012, Jun 16, 2005
Filed:
Jun 24, 2004
Appl. No.:
10/877813
Inventors:
Martin Pomper - Baltimore MD, US
John Musachio - Baltimore MD, US
Hong Fan - Lutherville Timonium MD, US
Robert Dannals - Sparks MD, US
Catherine Foss - Baltimore MD, US
Eifion Phillips - Wilmington DE, US
John Gordon - Wilmington DE, US
Dennis McCarthy - Wilmington DE, US
Richard Keith - Wilmington DE, US
Mark Smith - Wilmington DE, US

Peter Dorff - Wilmington DE, US
International Classification:
A61K051/00
A61K031/4747
C07D491/14
C07F005/00
US Classification:
424001110, 514278000, 534011000, 546018000
Abstract:
The present invention relates to radiolabelled compounds particularly 1-azabicyclo[2.2.2]octane compounds (i.e., quinuclidine compounds) which are labeled with one or more radioisotopes and which are suitable for imaging or therapeutic treatment of tissues, organs, or tumors which express the a7-nicotinic cholinergic receptor. In another embodiment, the invention relates to methods of imaging tissues, organs, or tumors using radiolabeled compounds of the invention, particularly tissues, organs, or tumors which express a7-nicotinic cholinergic receptor to which the compounds of the invention have an affinity.

Methods For Purifying Radiolabelled Compounds

US Patent:
2009000, Jan 1, 2009
Filed:
Feb 25, 2008
Appl. No.:
12/037011
Inventors:
John F. Valliant - Ancaster, CA
Peter Dorff - Glen Mills PA, US
Raman Chirakal - Brantford, CA
International Classification:
C07F 7/22
US Classification:
534 10
Abstract:
One aspect of the present invention relates to a method of purifying radiolabelled compounds comprising a) loading onto a fluorous polymer a radiolabelled compound precursor comprising a fluoroalkyl tin moiety; b) reacting the radiolabelled compound precursor with a radiolabel delivering compound to give a radiolabelled compound, wherein the fluoroalkyl tin moiety is replaced by a radiolabel; and c) eluting the radiolabelled compound from the fluorous polymer.
