The toxic dinoflagellate Karenia brevis, responsible for early harmful algal blooms in the Gulf of Mexico, produces many secondary metabolites, including potent neurotoxins called brevetoxins (PbTx). These compounds have been identified as toxic agents for humans, and they are also responsible for the deaths of several marine organisms. The overall biosynthesis of these highly complex metabolit...

Digestion of polyoma viral DNA with a restriction enzyme from Haemophilus aegyptius generates at least 22 unique fragments. The fragments have been characterized with respect to size and physical order on the polyoma genome, and the 5' to 3' orientation of the (+) and (-) strands has been determined. A method for specific radiolabeling of adjacent fragments was employed to establish the fragmen...

A selection of carbon-fluorine bond-forming reactions that have been developed in the recent past are presented. An overview of the most common fluorination reagents is followed by descriptions of fluorination reactions that are organized by reactivity. The distinction between nucleophilic and electrophilic fluorinations is highlighted, as well as between aliphatic and aromatic fluorinations. E...

The chemical modification of oligomers such as DNA, PNA, MORF, LNA to attach radionuclides for nuclear imaging and radiotherapy applications has become a field rich in innovation as older methods are improved and new methods are introduced. This review intends to provide a brief overview of several chelators currently in use for the labeling of oligomers with metallic radionuclides such as 99m ...

Introduction: Bone pain palliation therapy is a mandate in handling end-stage cancer patients. The development of new ligands with higher stability, better pharmacokinetics and lower unwanted tissue uptakes (liver and GI) is still ongoing. Methods: In this work Lu-177 labeled (3-amino-1-hydroxypropane-1,1-di-yl)-bis-(phosphonate) (Lu-pamidronate; LuPAM ), and (3-amino-1-hydroxybutane-1,1-di-yl)...
