Cancer has emerged as a leading cause of death throughout the world. Peptides are a novel class of anticancer agents that can specifically target cancer cells with low toxicity to normal tissues and thus, offer new opportunities for future cancer treatment. On the other hand, Ciprofloxacin, an antibiotic, also known to its anticancer property for enabling cell cycle arrest and creating double strand breaks in nucleic acid can trigger apoptosis of cancer cells. Thus, joining anticancer peptides with Ciprofloxacin may be good idea to get benefit of the both compounds’ properties and therefore gives better anticancer agents. The aim of this study was to synthesize Ciprofloxacin-cytotoxic peptide conjugates and to investigate the anticancer activity of the resultant compounds. The conjugates were prepared by solid phase peptide synthesis technique using Fmoc strategy. Anticancer activity of these compounds was examined …
