Doxycycline is a tetracycline-derivative wide-spectrum antibiotic, inhibit protein synthesis by interfering with the binding of activated aminoacyl-tRNAs on the A-site of the 30S subunit of bacterial ribosomes. It is used to treat a variety of infections caused by bacteria and protozoa. Doxycycline is also a nonspecific matrix metalloproteinase (MMP) inhibitor. Doxycycline exhibits anti-tumour and pro-apoptotic activity [1-4].
Doxycycline(0-250 µM; 72h) inhibits cell viability of breast cancer cells and mammospheres[5]. Doxycycline (100 ng/mL, 1 µg/mL; 24 h) reduces proliferation of human cell lines[6].
Doxycycline(20mg /kg; p.o.;2times) treated following mice TBI improved behavioral and motor function suggesting doxycycline's role in preserving murine BBB integrity[7]. Doxycycline(DOX in drinking water (6 mg/ml, 5 ml/day/mice) ; 36 days) significantly minimized the dystrophic phenotype of skeletal and cardiac muscles and improved forelimb muscle strength[8]. The FM(fecal microbiota) of female C57BL/6NCrl mice is significantly altered by administration of doxycycline(doxycycline in the drinking water at 2 mg/ml during weeks 1, 2, and 4) at a concentration of 2 mg/ml in the drinking water[9].
