生物活性:
Metronidazole hydrochloride (SC 326421) is an orally active nitroimidazole antibiotic, can be used to research anaerobic infections. Metronidazole hydrochloride can cross blood brain barrier and results inflammation and skeletal muscle contraction under long-term application.

体内研究:
Metronidazole hydrochloride (135 mg/kg/d; p.o.; 28 d) can cross the blood brain barrier, and exhibits neurotoxicity under long term administration in rats.Metronidazole hydrochloride (1 g/L; p.o.; 4 weeks) results skeletal muscle atrophy and changes the expression of genes involved in the muscle peripheral circadian rhythm machinery and metabolic regulation.Animal Model:Sprague-Dawley (SD) rats (200-220 g)
Dosage:135 mg/kg
Administration:Oral gavage; once daily; 28 days
Result:Caused inflammatory markers increasing, including iNOS, eNOS, Bax and caspase 3 protein expressions increasing and caused oxidative stress damage in brain tissue, with MDA content rising.
Animal Model:SPF C57Bl/6J mice (6-7 months old)
Dosage:1 g/L (full dose)
Administration:Oral gavage; provided with drinking water for 4 weeks, changed twice weekly
Result:Resulted the muscle core clock and effector genes Cry2, Ror-β, E4BP4, PP ARγ and adiponectin expression increasing. Decreased hind limb muscle weight and resulted in smaller fibers in the tibialis anterior muscle.

体外研究:
Metronidazole hydrochloride acts on anaerobic microorganism following: passage through the cell membrane; (b) reductive action; (c) interaction with intracellular targets; (d) release of inactive end products, exerts function with toxic nitro and nitroso derivatives.Metronidazole hydrochloride displays inhibitory activity towards anaerobic protozoa Trichomonas vaginalis, Entamoeba histolytica, Giardia lamblia, and Balantidium coli.Metronidazole hydrochloride (4-8 μg/mL) inhibits anaerobic bacteria and shows good bactericidal activity.Metronidazole hydrochloride (0.1 μg/mL-0.01 mg/mL; 12-96 h) induces granular formation and triggers apoptosis in Blastocystis sp.
