  • Publication number: 20230302159
    Abstract: Disclosed are compounds with the following structure (Formula (I)) where (Formula (II)) or (Formula (III)), X is an anion (e.g., a biologically suitable anion, such as, for example, chloride, iodide, and the like). Y is NH, NR10, or CR11R12. Z is a heteroatom (e.g., O, S, or Se). R and R1 are independently chosen from methyl, ethyl, propyl (e.g., n-propyl, isopropyl), butyl (e.g., n-butyl, isobutyl, tert-butyl), and the like, and combinations thereof. In various examples, R and R1 are not both oxygen atoms (such that an —NO2 is formed). R2 and R3 are independently chosen from methyl, ethyl, propyl (e.g., n-propyl, isopropyl), butyl (e.g., n-butyl, isobutyl, tert-butyl), and the like, and the like, and combinations thereof. R4, R5, R6, R7, R8, R9, R10, R11, and R12 are independently chosen from hydrogen, alkyl groups (e.g., methyl, ethyl, propyl (e.g., n-propyl, isopropyl), butyl (e.g., n-butyl, isobutyl, tert-butyl)), and the like, and combinations thereof.

  • Publication number: 20190111161
    Abstract: Compositions that include a phenol group conjugated to a lipid group to form a phenolic lipid. The lipid group may include a fluorophore and at least one lipid anchor. The lipid anchor may have a carbon number that ranges between 7 carbon atoms and 22 carbon atoms. Also, included are methods of making and using such phenolic lipids. Further included are methods of iodinating hydrophobic compounds such as phenolic lipids in aqueous based iodination protocols. Cosolvent formulations for use in such methods are also described.

  • Patent number: 5648471
    Abstract: A one vial method for labeling a sulfhydryl containing antibody or antibody fragment with technetium-99m is disclosed. The method comprises contacting an antibody mixture comprised of a sulfhydryl containing antibody or antibody fragment and a reducing agent with technetium-99m in an oxidized state. In a preferred embodiment, the antibody mixture further contains a water soluble ligand. A one vial kit for labeling a sulfhydryl containing antibody or antibody fragment with technetium-99m is also disclosed.
