Patent ID: 6875737

Claim:
A compound, having the structure wherein D1 and D2, independently, are selected from the group consisting of NH and NH 2 , wherein N represents any isotope of nitrogen, wherein H represents any isotope of hydrogen; “˜” independently, is selected from the group consisting of a single bond and a double bond; B represents, independently, any isotope of boron; A1 and A5 are, independently, selected form a group consisting of a C, a CX moiety and an N, wherein C represents any isotope of carbon, wherein X represents any atom that forms a single bond with C; each A2, A3, A4, A6, A7, and A8 are, independently, selected from a group consisting of a CX moiety, a CXZ moiety, a CZ moiety, an NX moiety, and an O, wherein X and Z, are, independently, selected from the groups consisting of any atom that forms a single bond and any atom that forms a double bond with C or N and wherein O represents any isotope of oxygen; wherein each Y1, Y2, Y3, and Y4 are, independently, selected from the group consisting of hydroxyl moiety and any reactive moiety that converts to a hydroxyl group moiety under physiologic conditions; and L represents a linker moiety containing a chain of atoms selected from the group consisting of a combination of C, O, N, S, and P atoms, connected by single bonds or by double bonds in a manner that does not violate the laws of chemistry and wherein S represents any isotope of sulfur and P represents any isotope of phosphorous, wherein L has a molecular weight ranging between 100 daltons and 2000 daltons, or L has a span ranging from 20 Å to 300 Å.
