5-Hydroxypyrazine-2-Carboxylic Acid 生物活性

描述 5-Hydroxypyrazine-2-Carboxylic Acid, a metabolite of anti-tuberculosis drug pyrazinamide (PZA). The PZA metabolite pyrazinoic acid (PA) is the active compound against M. tuberculosis. PZA and caffeine, in various doses (PZA=50 or 100 mg kg(-1) and caffeine= 0, 50, 100, and 150 mg kg(-1)), were administered to female Sprague-Dawley rats. PZA and its three main metabolites were quantified in 24 h urine samples by reversed phase-HPLC Concomitant administration of 100 mg kg(-1) caffeine and 50 mg kg(-1) PZA increased from the excretion (p<0.05) of the most water-soluble and the least toxic PZA metabolite 5-hydroxypyrazinoic acid (5-OH-PA) from 66.18+/-10.87 to 94.56+/-8.65 micromol/24 h. This effect was more pronounced when 100 mg kg(-1) of PZA was administered increasing excretion of 5-OH-PA from 113.28+/-70 to 173.23+/-17.82 micromol/24 h[1]. 5OH-PYCA dissociates in two steps, with the corresponding dissociation constants pK (a1)=3.42 and pK (a2)=7.96, designating 5OH-PYCA as a medium weak acid[2].
