摘要：

The synthesis, formulation and a complete physico-chemical characterization, by dynamic light scattering and small angle neutron scattering techniques, of new liposomal aggregates obtained by co-assembling an amphiphilic molecule containing a platinum complex, Peg1500-Lys(Pt-aminoEtGly)-Lys(C18)2, (abbreviated as (C18)2-PKAG-Pt), with a second amphiphilic monomer, (C18H37)2NCO(CH2)2CO(AdOO)5-Oct ((C18)2L5-Oct), containing the octreotide bioactive peptide, is reported. Liposomes of (C18)2-PKAG-Pt present a radius of 48nm, whereas the mixed aggregates (C18)2-PKAG-Pt/(C18)2L5-Oct at 90/10M ratio give larger liposomes with a radius of 84nm. In both cases, the bilayer thickness is similar to 5.3nm. Encapsulation of doxorubicin in mixed liposomes is also obtained by using the pH gradient method. The obtained liposomes could represent a new target selective cargo system for delivery of cisplatin based drugs and/or doxorubicin on cells overexpressing the sstr2 and sstr5 somatostatin receptors.
