体外研究 (In Vitro) |
telotristat etiprate 的活性成分是 telotristat。称为telotristat etiprate 的乙酯前药被降解产生telotristat。一种称为 telotristat etiprate 的口服血清素合成抑制剂用于治疗类癌综合征[1]。

体内研究 (In Vivo) |
口服给药后,发现telotristat etiprate 的水平非常低。快速水解成活性部分telotristat是导致这些低水平的原因。半衰期在四到十二小时之间。当在两周内给予多次剂量时,telotristat 不会蓄积。 Telotristat 暴露量大致与剂量成正比[1]。

毒性/毒理 (Toxicokinetics/TK) |
Hepatotoxicity
In small clinical trials of telotristat in patients with neuroendocrine tumors and symptomatic diarrhea despite stable doses of somatostatin analogues, transient, asymptomatic and mild serum elevations of ALT occurred in 4% to 5% and of GGT in 6% to 9% of treated subjects. Apparent liver injury with jaundice was not observed in the several prelicensure clinical trials and has not been reported in the limited clinical experience with this agent since its approval. Likelihood score: E (unlikely cause of clinically apparent liver injury). |

其他信息 |
Telotristat is a phenylalanine derivative.
A tryptophan hydroxylase inhibitor. [Telotristat ethyl] (brand name Xermelo) is a prodrug of telotristat. Telotristat is a Tryptophan Hydroxylase Inhibitor. The mechanism of action of telotristat is as a Tryptophan Hydroxylase Inhibitor. Telotristat is an oral, small molecule inhibitor of tryptophan hydroxylase that is used in the treatment of symptoms of carcinoid syndrome. Telotristat is associated with modest rate of minor serum enzyme elevations during therapy but has not been linked to cases of clinically apparent liver injury. Telotristat is a tryptophan hydroxylase (TPH) inhibitor, with potential anti-serotonergic activity. Upon administration, telotristat binds to and inhibits the activity of TPH. This may result in a reduction in peripheral serotonin (5-HT) production and improvement of serotonin-mediated gastrointestinal effects such as severe diarrhea. TPH, the rate-limiting enzyme in serotonin biosynthesis, is overexpressed in carcinoid tumor cells. See also: Telotristat Ethyl (active moiety of); Telotristat Etiprate (is active moiety of). |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
