Product Introduction
Bioactivity
| 名称 | Protirelin Acetate(24305-27-9 free base) |
| 描述 | Protirelin Acetate(24305-27-9 free base) (Thyroliberin Acetate) is a tripeptide that stimulates the release of thyrotropin and prolactin. |
| 动物实验 | Protirelin (TRH tartRatse) is dissolved in physiological saline (Rats).RatsNinety male Wistar rats weighing 200-250 g are subjected to the study. In the first experiment, 50 rats are divided into five groups randomly. Four doses of Protirelin dissolved in physiological saline, i. e., 1 mg/kg, 5 mg/kg, 10 mg/kg and 20 mg/kg, are administered intraperitoneally to the four groups and saline to the remaining control group. Rectal temperature is measured at the place 5 cm inner from the anus with the electronic thermister before and after treatment with Protirelin or saline. In the second experiment, 40 rats are thyroidectomized or sham-operated under the anesthesia by thiopental sodium. Ten days after the operation, 20 mg/kg of Protirelin or saline is administered to the thyroidectomized and sham-operated animals by i. p. and rectal temperature is measured using the same method as used in the first experiment. These two experiments are undertaken from 1 p, m, to 4 p. m. and the room temperature is kept at 24±1°C through the experiments including the breeding period. For a statistical analysis, Student's t test (two-tailed) is adopted. |
| 体内活性 | Protirelin(TRH)是一种进化古老的神经肽,在原口动物和后口动物分化之前就已存在,可能原本涉及控制胚后生长和繁殖。研究探讨了下丘脑释放激素之一的促甲状腺激素释放激素(Protirelin, TRH)对大鼠体温的影响。向体重200-250克的雄性Wistar大鼠腹腔内注射1、5、10和20 mg/kg的Protirelin。结果显示,Protirelin能够依剂量暂时性地提高体温。而在接受20 mg/kg Protirelin注射的甲状腺切除大鼠中,相较于假手术动物引发显著的高热反应,体温却未见上升。当前结果表明,甲状腺激素的释放可能参与Protirelin的高热作用。 |

文献和实验网络 第十九章 杂环化合物和生物碱 杂环化合物在自然界分布很广,其数量几乎占已知有机化合物的三分之一,用途也很多。许多重要的物质如叶绿素、血红素、核酸以及临床应用的一些有显著疗效的天然药物和合成药物等,都含有杂环化合物的结构。生物碱多是中草药的有效成分,绝大多数是含氮的杂环化合物。本章内容与医学关系密切,具有重要意义。
分子中具有高能键的化合物。在生物体内主要有上式(Ⅰ)和(Ⅱ)两种结构的高能化合物。其作用为贮藏能量(例如 ATP、肌酸磷酸)和作为产生 ATP源的中间代谢产物(例如磷酸烯醇丙酮酸)以及合成反应的中间物质(例如酰基辅酶 A),在蛋白质的结构( conformation)变化周期的第一阶段上(例如钠钾 ATP酶的羧基磷酸中间体)也具有重要作用。多数高等化合物具有磷酸基,但也有例外。
由不同种元素组成的纯净物叫做化合物。化合物一般有固定的组成。化合物的组成一般可用化学式表示。化合物具有确定的物理性质和化学性质,不同于其组成元素的性质。化合物中的元素不能用简单的机械方法或物理方法分开,而必须用化学方法才能分离。
