描述 | Potassium oxonate is a uricase inhibitor, affecting the phosphorylation of 5-FU into 5-fluorouridine-5'-monophosphate differently from allopurinol, both in cell-free extracts and intact cells. When administered orally alongside 5-FU (2 mg/kg) to Yoshida sarcoma-bearing rats, oxonic acid (10 mg/kg) specifically inhibits the conversion of 5-FU into its phosphorylated form and its incorporation into RNA in the intestines but not in tumor or bone marrow tissues[1]. Additionally, an oxonic acid diet raises plasma uric acid levels by 80-90 micromol/L, with an observed increase in blood pressure only in hyperuricemic rats subjected to a 5/6 nephrectomy (18 mmHg)[2]. |
