    摘要： There is disclosed a pharmaceutical composition which gels at physiological temperature. The composition is comprised of a block copolymer containing one or more polyoxyethylene blocks and one or more polyoxy (higher alkylene) blocks wherein at least some of the blocks are linked together by a linking group characterised in that the linking group is an oxymethylene group, and a therapeutic agent. The therapeutic agent is present as (i) nanoparticles of the therapeutic agent having the block copolymer adsorbed on the surface thereof, (ii) a suspension in a solution of the block copolymer, or (iii) as an aqueous solution in a solution of the block copolymer.

    摘要： The invention provides a novel compound having the structure ##STR1## wherein R is alkyl and R1, R2, R3 and R4 are each independently OCH3, H or I and n is 0 or 1 and m is 0 or 1.The compound is useful in a method of treating mammals either therapeutically or imaging mammals for diagnostic purposes. Useful therapeutic areas are in treating lymph nodes and tumors and diagnostic treatment is applicable to lymph nodes, tumors and in blood pool imaging. It is particularly advantageous to link an insoluble carrier molecule with a therapeutic or imaging agent to form the structure above. This makes the conjugate insoluble and thus amenable to forming nanoparticles.
