描述 | Phenazopyridine hydrochloride is a chemical, which has a local analgesic effect, often used to alleviate the pain, irritation, discomfort, or urgency caused by urinary tract infections, surgery, or injury to the urinary tract. Preoperative oral phenazopyridine is effective in more than 90% of cases to detect during gynecologic surgery. A higher phenazopyridine dose and lower intraoperative urine output were associated with increased efficacy[3]. Phenazopyridine hydrochloride was carcinogenic in Fischer 344 rats, inducing adenocarcinomas of the colon in both males and females. Although phenazopyridine hydrochloride was not carcinogenic in male B6C3F1 mice, the chemical was carcinogenic in females, inducing hepatocellular adenomas and carcinomas[4]. Dose-inhibition curves showed that three of these kinases interacted with phenazopyridine with sub-micromolar binding affinities: cyclin-G-associated kinase, and the two phosphatidylinositol kinases PI4KB and PIP4K2C, the latter being known for participating in pain induction. Docking revealed that phenazopyridine forms strong H-bonds with the hinge region of the ATP-binding pocket of these kinases. Phenazopyridine is a kinase inhibitor, impacting notably phosphatidylinositol kinases involved in nociception[5]. Phenazopyridine: (i) enhanced neuronal differentiation, (ii) increased cell survival, (iii) decreased the amount of non-neuronal and undifferentiated cells and (iv) synchronized the cellular differentiation state[6]. |
