Abstract:
Cancer targeting is crucial for cancer detection, therapy and targeted drug delivery. A dendrimer-peptide conjugate has been synthesized based on poly(amidoamine) dendrimer generation 5 (PAMAM G5) as a platform and a luteinizing hormone-releasing hormone (LHRH) peptide as a targeting moiety. The synthesized conjugate was fully characterized using nuclear magnetic resonance (NMR), UV-Vis spectrometry, reverse-phase high-performance liquid chromatography (RP-HPLC) and matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry. Further stability experiments showed that the synthesized conjugate was stable after 72-h incubation in phosphate-buffered saline (PBS) buffer (pH 7.4) at 37 degrees C. The synthesized conjugate may find applications in biomedical targeting, gene delivery and imaging.
