Page/Page column 41; 44, (2008/06/13)
The invention relates to compounds of formula: I, or pharmaceutically acceptable a salts thereof, I wherein X1 X2 and X3 are each independently where Y is an alkylene, alkenylene or alkynylene group, each of which may be optionally substituted with one or more substituents selected from alkyl, halo, CF3, OH, alkoxy, NH2, CN, NO2 and COOH; W is absent or is O, S or NH; Rl, R2, R3 and R4 are each independently selected from H, alkyl, aryl and a protecting group Pl; R7, R8 and R9 are each independently selected from H, alkyl, halo, CF3, OH, alkoxy, NH2, CN, NO2 and COOH; q and r are each independently 1, 2, 3 or 4; q' and r' are each independently 0, 1, 2 or 3, where q + q' and r + r' each equal 4; p is 1, 2, 3, 4 or 5, and p' is 0, 1, 2, 3 or 4, where p + p' is 5; n is 0, 1, 2, 3....6; L is (Z)mNR5R6 where Z is a hydrocarbyl group and m is 0 or 1; where R5 and R6 are each independently H, CO(CH2)jQ1 or C=S(NH)(CH2)kQ2 where j and k are each independently 0, 1, 2, 3, 4 or 5, and Q1 and Q2 are each independently selected from COOH, a chromophore or R5, R6 and the nitrogen to which they are attached together form.
