n1
(I). The targeting peptide is cyclo[L-Phe-L-Tyr-L-Lys(iPr)-D-Arg-L-2-Nal-Gly-D-Glu]-L-Lys(iPr). R
1
is H or methyl. X
1
is an optionally substituted C
1
-C
15
hydrocarbon optionally comprising heteroatoms. R
2
is C(O)OH or C(O)NH
2
. L
1
is a linkage (thiolether, amide, maleimide-thiol, triazole). The linker has a net negative charge at physiological pH and is a linear or branched chain of 1-10 units of X

and/or X
2
(L

)
2
, wherein: each X
2
is, independently, an optionally substituted C
1
-C
15
hydrocarbon optionally comprising heteroatoms; and each L
2
is a linkage. The linker optionally further comprises an albumin binder bonded to an L
2
. Each R
X
is a radiolabelling group linked through a separate L
2
, selected from: a metal chelator; a prosthetic group containing trifluoroborate (BF
3
); or a prosthetic group containing a silicon-fluorine-acceptor moiety. The compounds may be useful for imaging CXCR4-expressing tissues or for treating CXCR4-associated diseases or conditions (e.g. cancer).
