英文摘要 | Screening for anti-anaerobic drug candidates is still challenging although the anaerobic bacteria are important sources for human infections, because the method for anti-anaerobic activity testing is not readily available with low-cost and -expertise. We report a novel method for the determination of the anti-anaerobic activity of drug candidates by automated headspace-gas chromatography (HS-GC). Anaerobic bacteria were inoculated in an anaerobic atmosphere or rapidly using sterile syringe in an air-tight manner, and incubated with and without drugs for 48 h. The metabolic acidities of the cultured media were used as an indicator of cell activities and measured as end-products in place by HS-GC after being completely converted to CO2 with sodium bicarbonate. The present method is precise (relative standard deviation is below 5%) and validated by excellent agreements with a reference method on the determinations of the inhibition rates (root-mean-square error = 10%, n = 48) and half maximal inhibitory concentrations (R-2 = 0.996, n = 8) of both pure drug compounds and plant extracts. Advantageously, the present method is sensitive in response to cell activity, safe with regard to cross contamination, and suitable for routine screening of diversified drug candidates for anti-anaerobic activity.
