TMPD dihydrochloride是一种用于研究细胞色素c的膜栓系化合物，用于研究其对酵母细胞死亡的影响。TMPD dihydrochloride 也是一种 complex IV 的底物。在氧化酶试验中，通常使用氧化还原介质N、N、N '、N'-四甲基对苯二胺 (TMPD)进行比色鉴定细胞培养中的病原菌和非病原菌。使用TMPD在COX活性的高通量微孔板测定中可能成为筛选抑制体内 COX 活性的潜在治疗剂的首选方法。

| 方法 | Bacteria culture and oxidase test Escherichia coli Bacteria were cultured in 2 × TY liquid microbial growth medium (broth), containing 16 g/L tryptone, 10 g/L yeast extract and 5.0 g/L NaCl. Growth medium was inoculated with bacteria from frozen stocks and incubated in glass culture flasks for 18 h at 37 °C in an incubator shaker. An E. coli suspension of 50 μL was transferred into a new culture flask, containing fresh growth medium. Following incubation for 3 to 4 h at 37 °C, the number of bacteria in solution was determined by optical density (OD) at a wavelength of 600 nm (OD600 of 1.0 = 8 × 108cells/mL). When an OD600 between 0.4 and 1.8 was reached, bacteria were harvested by centrifugation for 15 min at 3000 rcf and re-suspended in pre-warmed (37 °C) PBS. Bacillus subtilis (strain PY79) Low salt growth medium (broth), containing 10 g/L tryptone, 5.0 g/L yeast extract and 5.0 g/L sodium chloride, was inoculated with cultures from frozen stocks and incubated at 30 °C for 36 h in an incubator shaker. An OD600 was determined to calculate number of bacteria in solution (OD600 of 1.0 = 5 × 108cells/mL). Bacteria were harvested by centrifugation for 10 min at 300 rcf and re-suspended in pre-warmed (30 °C) PBS. Cultures grown on agar, containing 10 g/L tryptone, 5.0 g/L yeast extract 5.0 g/L sodium chloride and 20 g/L agar, were inoculated onto agar plates and grown at 30 °C for 36 h in a static incubator. For the oxidase test, 200 μL of a 1% (wt) N,N,N′,N′-tetramethyl-p-phenylenediamine dihydrochloride (TMPD-2HCl) solution was added to 1 mL of cell suspension (1 × 107cells/μL). Images were taken within 30 s of solution mixture. |

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
