| 体内研究 (In Vivo) |
本研究旨在评估印楝果皮四氯化碳提取物(CTCE)及其分离成分azadiradione在两种不同剂量水平(50和100 mg kg⁻¹体重)下的抗疼痛和抗炎活性。扭体试验和热板技术进行的抗伤害性筛选分别支持外周和中枢机制。使用角叉菜胶诱导的足肿胀模型观察抗炎活性。研究结果表明,用100mg kg⁻¹剂量的CTCE和印楝素处理的动物表现出显著的抗疼痛和抗炎活性。这项研究使部落人民对这种植物的民族医学用途进行了合理化,用于治疗伤口、烧伤和损伤。[1]
这项研究表明,通过Azadiradione/印楝素(一种在印度楝树种子中发现的生物活性柠檬苦素)部分拯救HD模型小鼠中有缺陷的蛋白质质量控制可能会改善疾病病理。对HD小鼠进行长时间的印楝素治疗,显著改善了体重的逐渐恶化、运动功能以及寿命的延长。与年龄匹配的盐水处理的HD对照组相比,阿扎司琼治疗的HD小鼠脑也表现出突变亨廷顿蛋白聚集物负荷的大幅减少和纹状体病理学的改善。生化分析进一步揭示,在印楝素处理的小鼠中,不仅HSF1(蛋白质折叠的主要调节因子)上调和激活,而且Ube3a(一种参与清除突变亨廷顿蛋白的泛素连接酶)也上调和激活。我们的结果表明,印楝素介导的突变亨廷顿蛋白增强折叠和清除可能是改善HD小鼠疾病病理的基础,并表明它可能是一种延缓HD进展的潜在治疗分子[2]。 |

Transgenic mouse line for HD (strain B6CBA-Tg (HDexon1) 62Gpb/3 J) was procured from The Jackson Laboratory and bred in the animal house facility of National Brain Research Centre. This HD transgenic mouse line (commonly referred as R6/2 line) expresses Exon1 region of huntingtin with 120 CAG repeats and exhibits very fast progressive neurological phenotype [44]. Animals had free access to pelleted diet and water ad libitum. All experiments were conducted according to the strict guideline proposed by the Committee for the Purpose of Control and Supervision of Experiments on Animals (CPCSEA), Ministry of Environment and Forestry, Government of India and were approved by the Institutional Animal Ethics Committee of the National Brain Research Centre (Protocol number NBRC/IAEC/2017/120). After proper genotyping, female HD mice along with their wild type littermates were used for the present study. Azadiradione was dissolved in DMSO, diluted in saline (containing 5% DMSO) and then given intraperitoneal injection (dose 10 mg/kg body weight) to wild-type and HD mice at their age of 55 days. Each mouse was received total 15 doses at 1-day interval. In some pilot experiments, wild-type mice were treated azadiradione at a dose of 1 and 10 mg/kg body weight every day for 10 days. Control mice received with same volume of saline containing 5% DMSO.[2]

Azadiradione is a tetracyclic triterpenoid that is 4,4,8-trimethylandrosta-1,14-diene substituted by oxo groups at positions 3 and 16, an acetoxy group at position 7 and a furan-3-yl group at position 17. Isolated from Azadirachta indica, it exhibits antimycobacterial and anti-inflammatory activities. It has a role as a plant metabolite, an antimycobacterial drug and an anti-inflammatory agent. It is a limonoid, a tetracyclic triterpenoid, an acetate ester, a cyclic terpene ketone and a member of furans.
Azadiradione has been reported in Dysoxylum parasiticum, Quivisianthe papinae, and other organisms with data available. |

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) 。
