Abstract

Poly-[N-(2-hydroxyethyl)-l-glutamine](PHEG) and poly (ethylene glycol)(PEG)-grafted PHEG conjugates of N, N-di (2-chloroethyl)-4-phenylenediamine mustard (PDM) were synthetised. A collagenase-sensitive oligopeptide spacer was selected to link the cytotoxic agent PDM onto the polymeric carrier. First, the oligopeptide-drug conjugate, l-pro-l-leu-gly-l-pro-gly- PDM, was prepared. In a second step, the low molecular weight PDM derivative and PEG- ...
