| Assignees: | The Board of Regents of the University of Michigan (Ann Arbor, MI) |
| Claim: | Wath is claimed is |
| Claim: | 1. A compound having the general formula: ##STR17## where n=1-15, except n=1-14 where m=0 and Y=--N((CH.sub.3).sub.3 ; X is selected from the group consisting of ##STR18## where m=0-15 and Z is a radioactive isotope of iodine; Y is selected from the group consisting of NH.sub.2, NR.sub.2, NR.sub.3 ; and R is selected from the group consisting of alkyl and aralkyl substituents. |
| Claim: | 2. The compound of claim 1 wherein Z is selected from the group consisting of .sup.122 I, .sup.123 I, .sup.125 I, and .sup.131 I. |
