A new designed hybrid peptide FSH33-53-Lytic was synthesized and expected to combine the follicle stimulating hormone receptor (FSHR) targeting and tumor cell membranes disintegration. Through in vitro and vivo study, no significant enhancement on anti-tumor activity was shown compared with Lytic peptide only. We also prepared 18F-Al-NOTA-MAL-FSH33-53-Lytic and use microPET image to observe the FSHR targeting of FSH33-53-Lytic. No accumulation in the tumor may explain the failure of FSH33-53-Lytic on cancer therapy. In summary, microPET image can provide more accurate and visible information for screening new anti-tumor agents.
