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.
本文披露了包含螯合基团的烷基磷脂醇类似物,该螯合基团与放射性金属同位素形成螯合。这些烷基磷脂醇类似物可用于治疗或检测固体肿瘤,其化学式为:[此处应插入化学式]。R1包括一个与金属原子螯合的螯合剂,其中金属原子是具有半衰期大于或等于4小时的正电子或单光子发射金属同位素,或者是具有半衰期大于6小时且小于30天的α、β或奥格发射金属同位素;a为0或1;n为12到30的整数;m为0或1;Y为-H、-OH、-COOH、-COOX、-OCOX或-OX,其中X为烷基或芳基烷基;R2为-N+H3、-N+H2Z、-N+HZ2或-N+Z3,其中每个Z独立地为烷基或芳基烷基;b为1或2。
