RESUMO
A novel peptide containing the lysosomally degradable sequence GlyPheLeuGly and a sequence-inverting unit has been prepared. This peptide presents the methylamino groups of sarcosine (N-methylglycine) at both termini for co-polymerisation with alpha, omega-bis(oxiranylmethoxy)poly(ethylene glycol) of mean M(w) 1650. Gel permeation chromatographic analysis showed the presence of a mixture of oligomers. Preliminary degradation studies showed that these oligomers are cleaved by cathepsin B, an important lysosomal enzyme.
