Abstract:
Novel radioiodinated analogues of naturally-occurring phospholipid ethers are tumor-specific and have a triglycerol backbone structure which is substituted at the 3-position with an alkyl phosphocholine and include a monoiodinated benzoyl side chain substituted at either the 1- or 2-position. In some embodiments of the invention, the monoiodinated aralkyl side chain may be substituted directly onto alkyl phosphocholine in accordance with general Formula: provided that one and only one of X or Y is a monoiodinated aralkyl ##STR1## where Y=NH. sub. 2, NR. sub. 2, NR. sub. 3, NR. sub. 2 R'
R=alkyl, aralkyl
R'=a monoiodinated aralkyl, such as ##STR2## Z=. sup. 122 I,. sup. 123 I,. sup. 125 I, and. sup. 131 I n=1-15
X=a monoiodinated aralkyl, like R', where n=1-15; or an alkyl, such as --CH. sub. 2 --(CH). sub. m --CH. sub.
