Co-delivery of drug nanoparticles and siRNA mediated by a modified cell penetrating peptide for inhibiting cancer cell proliferation

Co-delivery of anti-cancer agent Ellipticine (EPT) and Bcl-2 siRNA was mediated by a modified cell penetrating peptide, stearylated H16R8 (STR-H16R8). The stability and efficacy of the EPT nanoparticles was improved significantly by the amphiphilic peptide. Efficacy of STR-H16R8 stabilized EPT nanoparticles was further enhanced with Bcl-2 siRNA.
