    In Vitro

    In vitro activity: Enoxacin, a fluoroquinolone used as an antibacterial compound, enhances the production of miRNAs with tumor suppressor functions by binding to the miRNA biosynthesis protein TAR RNA-binding protein 2 (TRBP). Enoxacin binds to the DNA active site and alters the breakage/reunion activity of the enzyme. Enoxacin stimulates cleavage of both relaxed and supercoiled forms of DNA in the absence of ATP, whereas CcdB induces cleavage only after many cycles of ATP-dependent breakage and reunion. Enoxacin dose dependently reduces the number of osteoclasts differentiating in mouse marrow cultures stimulated with 1,25-dihydroxyvitamin D(3), as well as markers of osteoclast activity, and the number of resorption lacunae formed on bone slices. Enoxacin inhibits osteoclast formation at concentrations where osteoblast formation is not altered. Enoxacin dose-dependently reduces the number of multinuclear cells expressing tartrate-resistant acid phosphatase (TRAP) activity produced by RANK-L-stimulated osteoclast precursors. Enoxacin directly inhibits osteoclast formation without affecting cell viability by a novel mechanism that involves changes in posttranslational processing and trafficking of several proteins with known roles in osteoclast function. Enoxacin is able to decrease cell viability, induce apoptosis, cause cell cycle arrest, and inhibit the invasiveness of prostate cancer (PCa) cell lines. Enoxacin is also effective in restoring the global expression of miRNAs in prostate cancer (PCa) cell lines.
