产品描述 | L-Thyroxine sodium salt pentahydrate, also known as Levothyroxine, is a synthetic hormone utilized in the study of hypothyroidism. It is biologically activated into Triiodothyronine (T3) from its original form, L-Thyroxine (T4), through conversion by DIO enzymes. |
体内活性 | L-Thyroxine (T4) and Triiodothyronine (T3) hormones are known to modulate the expression of ionic channels, pumps, and regulatory contractile proteins. Moreover, thyroid hormones have been shown to influence calcium homeostasis and flux responsible for excitation and contractility, with L-Thyroxine and Triiodothyronine modulating its pharmacological control and secretion. Deiodinases, which catalyze the conversion of thyroxine (pro-hormone) to the active thyroid hormone, is associated with thyroid-stimulating hormone (TSH) levels. DIO1 and DIO2 catalyze the activation of thyroid hormone secretion in contrast to DIO3 playing role inactivation of the secretion. Activities of DIO1 and DIO2 play a pivotal role in the negative feedback regulation of pituitary TSH secretion [1]. A significant decrease in the levels of both Triiodothyronine and L-Thyroxine is observed when compared to the control group fed with a standard diet (p<0.001), in rats fed 12 weeks with the iodine-free diet. An increase in L-Thyroxine levels is observed (p=0.02) while Triiodothyronine levels remain virtually similar to the control group (p=0.19), in the group treated with low doses of L-Thyroxine. Rats treated with high doses of L-Thyroxine show a significant increase in both Triiodothyronine and L-Thyroxine circulating concentrations compared to the non-treated hypothyroid group (p<0.001 and p=0.004, respectively) and a significant increase in L-Thyroxine levels when compared to the control values (p=0.03) [2]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
