Claim 0:
1. A compound of formula (Ib), or a pharmaceutically acceptable salt thereof, wherein:
R1 is alkyl;
R2 is H or alkyl, which alkyl is optionally substituted with at least one substituent selected from —NH2, —NH—C(═NH)—NH2, —C(O)NH2, —C(O)OH, —OH, —SH, —SCH3 and a 5 to 10-membered carbocycle or 5 to 10-membered heterocycle containing oxygen, nitrogen or sulfur as heteroatom(s);
R3 is H or alkyl, which alkyl is optionally substituted with at least one substituent selected from —NH2, —NH—C(═NH)—NH2, —C(O)NH2, —C(O)OH, —OH, —SH, —SCH3 and a 5 to 10-membered carbocycle or 5 to 10-membered heterocycle containing oxygen, nitrogen or sulfur as heteroatom(s);
R4B is alkyl substituted with one —SRA;
R5 is H or I;
R6B is alkyl substituted with one substituent selected from —NH2, —NH—C(═NH)—NH2, —NH—C(═NH)—NH—R14, and —NH—C(═NH)—NH—C(═O)—R15,
R7 to R10 are each independently H or alkyl;
R14 and R15 are independently C1-C10 alkyl, which alkyl is optionally substituted by at least one substituent selected from —NH—C(═O)—CH3 and —C≡CH; and
RA is a group which comprises at least one selected from:
(i) a chelating moiety,
(ii) a chelate wherein a chelating moiety (i) is bound to a chelated radioactive or non-radioactive cation,
(iii) a phosphonate moiety, and
(iv) a fluorescent label.
