IC50 & Target |
EC50: 65 nM (FXR)[1] |
In Vitro |
Treatment with different concentrations of GW4064 (1, 2.5, 5, 10 μM) reduces the lipid accumulation in the cells. Concordantly, GW4064 treatment significantly represses oleic acid-induced CD36 protein levels in a dose-dependent manner. Taken together, these data indicate that prevention of hepatic lipid accumulation is likely due to an inhibition of Cd36 expression by long-term GW4064 treatment[2]. |
In Vivo |
GW4064 suppresses weight gain in C57BL/6 mice fed with either a high-fat diet (HFD) or high-fat, high-cholesterol diet. GW4064 treatment of mice on HFD significantly represses diet-induced hepatic steatosis as evidenced by lower triglyceride and free fatty acid level in the liver. GW4064 markedly reduces lipid transporter CD36 expression without affecting expression of genes that are directly involved in lipogenesis. GW4064 treatment attenuates hepatic inflammation while having no effect on white adipose tissue[2]. GW4064 (30 mg/kg) treatment results in substantial, statistically significant reductions in serum activities of ALT, AST, LDH, and ALP in the ANIT-treated rats. Serum bile acid levels are also significantly reduced by GW4064 treatment. Bilirubin levels are decreased in the GW4064-treated rats, but statistical significance is not achieved. Notably, GW4064 is much more effective in decreasing these markers of liver damage than TUDCA, which reduces only LDH levels[3]. |

Cell Assay
[2] |
GW 4064 is dissolved in DMSO and stored, and then diluted with appropriate media before use[2]. Mouse liver cells (BNL CL.2) are maintained in a humidified incubator under 5% CO2 at 37°C in Dulbecco"s Modified Eagle"s Medium (DMEM) supplemented with 10% fetal bovine serum (FBS) and 1% Penicillin/Streptomycin. When cells are divided into six-well plates and reach ~90% confluence, sub-confluent cells are washed three times with phosphate buffered saline (PBS) and replaced with serum-free DMEM supplemented with 1% fatty acid-free BSA. Oleic acid (final concentration 500 μM) and GW4064 at various concentrations are added and incubated for 24 h. Cells are then fixed with 4% formaldehyde for Oil Red O staining or harvested for protein and western blot analysis[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |

求助各位大神,现在想购买小分子数据库,求大神推荐。
我知道的免费的数据库有zinc
求推荐哪家公司或者研究所的小分子数据库可以购买,十分感谢!!!!!!
就是蛋白质分子的小片断
是氨基酸形成的
westblot蛋白免疫印迹实验跑小分子蛋白(15kd)条带一直是波浪状,有人说是胶的问题,可同时跑了36kd蛋白,条带是直的,有人说是要恒流跑,电压不要太大,我的转膜条件是50v,50min,请教各位大神指点,万分感谢!!!
有机的是有机化合物的简称,它指的是含碳化合物.
但是,有四大类常见物质一般不作为有机物处理:
1、碳的氧化物,如CO和CO2.
2、碳酸及其盐,如CaCO3.
3、金属碳化物,如CaC2.
4、拟卤素及其化合物,如(CN)2与KSCN.
水的化学式为H2O,它不含有碳元素,故不是有机物.
但若所描述的水不是化学意义的水,而是自然界存在的天然水,那么,水中会溶有一定量的有机物.

【新闻事件】:在日前正在举行的美国神经学年会上MitsubishiTanabe公布了其ALS药物Edaravone的一个三期临床试验结果。在标准疗法基础上加入Edaravone显著改善ALS患者综合功能指标ALSFRS-R(-5.0对-7.5),同时也改善运动、呼吸等局部功能。Edaravone已经在韩国日本批准用于ALS,去年10月申请在美国上市,今年6月之前有望批准。
【药源解析】:ALS全称叫“肌肉萎缩性侧面硬化病”,也称LouGehrig氏病,因为30年代美国纽约洋基棒球队著名选手LouGehrig死于这个病。2014年风行一时的冰桶挑战让更多人知道了ALS,但ALS新药发现依然缓慢。美国目前只有riluzole这一个上市药物,能增加~10%的一年生存机会。
ALS的发病机理未知,动物模型十分不可靠,所以这个病的新药开发很难。过去10年大约只有十几个药物进入临床,基本全军覆没。走的最远的是百建艾迪的dexpramipexole,2013年初在三期临床失败。Edaravone号称是游离基清除剂,但分子机理未知。Edaravone最早作为中风药物开发,后来扩展到ALS。第一个三期临床失败,今天公布的是症状较轻患者。这个临床是日本人群,Edaravone并没有在美国IND和开展临床试验,所以如果批准将是比较特殊的情况(和Marathon的DMD药物Emflaza情况类似)。
Edaravone的另一个特殊性质是其分子结构。这个化合物分子十分简单,分子量只有174,可以算作是超小分子药物。现在有几十个分子量小于200的FDA批准药物,这类药物因为官能团数目有限不大可能与任何靶点有较高结合能,所以通常靶点未知。靶点未知又没有可靠动物模型,这类药物发现就更加困难。当然动物模型预测性差不是超小分子药物才面临的难题,多数神经系统药物、甚至现在最火热的肿瘤免疫疗法也面临同样问题。
这种临床前缺乏可靠评价体系的药物可以算是有D无R,这要求厂家冒更大的临床风险。只有潜在回报较大如没有任何标准疗法的罕见病或真正颠覆性药物如免疫疗法才可以适当采用这个模式。这个模式扩大化对厂家的长期生存是个威胁,因为新药的未知因素已经很多、成功率已经很低。没有临床前适当去风险的机会主义不可持续。
