-
, (2018/02/28)
Alkylphosphocholine analogs incorporating a chelating moiety that chelates a radioactive metal isotope are disclosed herein. The alkylphophocholine analogs, which can be used to treat or detect solid tumors, have the formula: [Formula should be inserted here]. R1 includes a chelating agent that is chelated to a metal atom, wherein the metal atom is a positron or single photon emitting metal isotope with a half life of greater than or equal to 4 hours, or an alpha, beta or Auger emitting metal isotope with a half life of greater than 6 hours and less than 30 days; a is 0 or 1; n is an integer from 12 to 30; m is 0 or 1; Y is -H, -OH, -COOH, -COOX, -OCOX, or -OX, wherein X is an alkyl or an arylalkyl; R2 is -N+H3, -N+H2Z, -N+HZ2, or -N+Z3, wherein each Z is independently an alkyl or an aroalkyl; and b is 1 or 2.
LONG-LIVED GADOLINIUM BASED TUMOR TARGETED IMAGING AND THERAPY AGENTS

Alkylphosphocholine analogs incorporating a chelating moiety that is chelated to gadolinium are disclosed herein. The alkylphophocholine analogs are compounds having the formula: (I) or a salt therof. R1 includes a chelating agent that is chelated to a gadolinium atom; a is 0 or 1; n is an integer from 12 to 30; m is 0 or 1; Y is -H, -OH, -COOH, -COOX, -OCOX, or -OX, wherein X is an alkyl or an arylalkyl; R2 is -N+H3, -N+H2Z, -N+HZ2, or -N+Z3, wherein each Z is independently an alkyl or an aroalkyl; and b is 1 or 2. The compounds can be used to detect solid tumors or to treat solid tumors. In detection/imaging applications, the gadolinium emits signals that are detectable using magnetic resonance imaging. In therapeutic treatment, the gadolinium emits tumor-targeting charged particles when exposed to epithermal neutrons.
