ABUO-RAHMA A1 MOUSTAFA FATHY YR 2020 UL http://ar.iiarjournals.org/content/40/5/2739.abstract AB Background/Aim: Ciprofloxacin has been used as an antibiotic in the clinic for decades. Recently, ciprofloxacin and its derivatives have shown promising anti-proliferative and cytotoxic activities against several malignant cells. The aim of this study was to investigate the effect of a new derivative of ciprofloxacin on colorectal cancer (HCT116) and non-small lung carcinoma (A549) cells. Materials and Methods: Cell viability was detected by the MTT assay. Flow cytometry was used to examine the cell cycle and apoptosis. Expression of bax, bcl2, p53 and p21 was investigated by qRT-PCR and western blotting. Results: Ciprofloxacin-derivative had an anti-proliferative effect on both cell lines in a concentration-dependent manner and caused cell cycle arrest at the G2/M phase and apoptosis. p53 and Bax proteins were overexpressed, while p21 and bcl2 gene expression was decreased after treatment with the ciprofloxacin derivative. Conclusion: This new ciprofloxacin derivative can be potentially used for the treatment of colorectal cancer and non-small lung carcinoma.
