  This application relates to compounds of Formula (I): [targeting peptide]-N(R1)-X1(R2)L1-[linker]-RX 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). R1 is H or methyl. X1 is an optionally substituted C1-C15 hydrocarbon optionally comprising heteroatoms. R2 is C(O)OH or C(O)NH2. L1 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 X2L2 and/or X2(L2)2, wherein: each X2 is, independently, an optionally substituted C1-C15 hydrocarbon optionally comprising heteroatoms; and each L2 is a linkage. The linker optionally further comprises an albumin binder bonded to an L2. Each RX is a radiolabelling group linked through a separate L2, selected from: a metal chelator; a prosthetic group containing trifluoroborate (BF3); 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).
