Abstract: PURPOSE: As a new macrolide antibiotic with independent intellectual property rights of China, carrimycin not only has good antibacterial effect on a variety of bacteria, but also has the function of regulating cell physiology and proliferation.The aim of this study was to investigate the anti-tumor effects of carrimycin on the biological activity of oral squamous cell carcinoma (OSCC) cells in vitro. METHODS: OSCC cells (HN6/HB96 cell lines) were treated with gradient concentration of carrimycin. Cell proliferation was detected using CCK-8 kit, based on which cell growth curve was drawn. Cell migration ability was analyzed by wound-healing assay. Cell clone formation ability was analyzed by clone formation assay. Cell cycle and apoptosis were analyzed by flow cytometry. SPSS18.0 software package was used for statistical analysis. RESULTS: Carrimycin concentration-dependently inhibited cellular proliferation of OSCC cells of HN6 and HB96 in vitro. With the increase of drug concentration, cell migration and clonal formation ability significantly decreased (P<0.05). The G1 phase ratio of OSCC cells treated with carrimycin significantly increased, while the S and G2/M phase ratio decreased, indicating that the cell cycle was arrested in G1 phase(P<0.001). The apoptosis rate of OSCC cells was significantly increased with the increase of drug concentration (P<0.01). CONCLUSIONS: The activity of OSCC cells can be effectively inhibited by carrimycin, which provides experimental evidence for the application of carrimycin in OSCC.
