代谢
替吡拉西尔在首次通过时不会发生大量代谢。它既不被肝脏或肝细胞代谢,也不被细胞色素P450酶代谢。在人类血浆、尿液或粪便中发现的唯一一种替吡拉西尔衍生的代谢物是6-羟甲基尿嘧啶(6-HMU),这并不是替吡拉西尔独有的。这种代谢物被认为是通过肠细菌代谢形成的。在血浆中,这两种代谢物的比例分别为替吡拉西尔53.1%,6-HMU 30.9%。
Tipiracil does not undergo much metabolism upon first pass. It is not metabolized by the liver or hepatocytes, nor by the cytochrome P450 enzymes. The only tipiracil-derived metabolite found in very small quantities in human plasma, urine or faeces is 6-hydroxymethyluracil (6-HMU) which is not unique of tipiracil. This metabolite is though to be formed either by enterobacterial metabolism. In plasma, this two metabolites can be found in a proportion of tipiracil 53.1% and 6-HMU 30.9%.

毒理性
  • 蛋白质结合
替吡拉西尔与蛋白质的结合度不高,其血浆蛋白结合率低于8%。
Tipiracil does not bind highly to proteins and presents a plasma protein binding below 8%.

吸收、分配和排泄
  • 吸收
替吡瑞尔的吸收被认为是通过胃肠道完成的。给予单次35 mg/m2剂量含有替吡瑞尔和三氟尿嘧啶的TAS-102,替吡瑞尔的吸收率产生AUC 301 ng·h/ml,最大观察到的血浆浓度(Cmax)为69 ng/ml,最大观察到的血浆浓度时间(Tmax)为3小时。高脂肪和高热量餐食的摄入可以将Cmax和AUC降低40%。
Absorption of tipiracil is suggested to be done by the gastrointestinal tract. Administration of a single 35 mg/m2 dose of TAS-102 containing tipiracil and trifluridine, generates the absoprtion rates of tipiracil of AUC 301 ng h/ml, maximum observed plasma concentration (Cmax) 69 ng/ml and time for maximum observed plasma concentration (Tmax) 3 h. The consumption of a high-fat and high-calorie meal can decrease Cmax and AUC by 40%.

吸收、分配和排泄
  • 排除途径
替比拉韦的主要部分以原形在粪便中排泄(49.7%),其次是尿液(27%)。尿液排泄中,79.1%是未改变的替比拉韦,而14%是6-HMU。另一方面,粪便排泄分析显示,48.2%是未改变的替比拉韦和34
The main fraction of tipiracil is excreted unchanged in the mainly in the faeces (49.7%) followed by the urine (27%). From the urine excretion 79.1% is accounted by unchanged tipiracil while 14% is 6-HMU. On the other hand, the faeces elimination analysis was formed by 48.2% unchanged tipiracil and 34.4% 6-HMU.

吸收、分配和排泄
  • 分布容积
在给予35 mg/m2 TAS-102单次剂量后,患有晚期实体瘤的患者中记录了替比拉西的分布体积为333升。
After a single TAS-102 dose if 35 mg/m2 in patients with advanced solid tumors, it was recorded a volume of distribution of tipiracil of 333 L.

吸收、分配和排泄
  • 清除
单个35毫克/平方米的TAS-102在晚期实体瘤患者中产生tipiracil的清除率为109升/小时,总剂量的77%被回收。
A single 35mg/m2 of TAS-102 in patients with advanced solid tumors produces a clearance rate of tipiracil of 109 L/hr, with a recovery rate of 77% of the total dose.

制备方法与用途

生物活性

Tipiracil 是一种胸苷磷酸化酶 (TPase) 抑制剂。

靶点
  • thymidine phosphorylase
体外研究
  • Tipiracil 是 thymidine phosphorylase 的抑制剂。通过抑制 thymidine phosphorylase 对 trifluridine 的代谢,Tipiracil 增加了 trifluridine 的暴露量。Tipiracil 与 trifluridine 的联合治疗是一种新的口服药物组合,用于治疗转移性结直肠癌。作为胸苷磷酸化酶抑制剂,Tipiracil 还通过首过效应防止 FTD 的降解。
