  • Patent number: 10717713
    Abstract: Novel compositions of matter based on homopiperazine precursor materials and forming a homopiperazine-based ligand are disclosed, along with suitable techniques and materials for the synthesis and utilization thereof. In particular various synthetic schemes and techniques for applying the disclosed compositions of matter as a decontaminating agent. The decontaminating agents include homopiperazine-based ligand-metal complexes that are particularly effective at neutralizing toxicity of nerve agents, pesticides, and other toxic organophosphorus-based compounds. In preferred approaches, the homopiperazine-based ligand-metal complexes act as catalysts to facilitate substitution of a leaving group of the organophosphorus-based compound with a functional group that does not permit the organophosphorus-based compound to inactivate acetylcholinesterase upon introduction of the organophosphorus-based compound to a living organism such as insects and mammals.

  • Patent number: 5512451
    Abstract: In enhanced chemiluminescent (ECL) reactions of a fused aromatic diacyl cyclic hydrazide such as luminol, a peroxidase enzyme catalyst, an oxidant such as hydrogen peroxide and an enhancer, it has been found advantageous to use a combination of an organoboron enhancer such as 4-biphenylboronic acid with a non boron-containing enhancer, especially a phenolic or aromatic amine enhancer, particularly 4-iodophenol. ECL reactions are useful in diagnostic assay.
