| Kinase experiment [1]: | |
Inhibitory assays | Inhibition of HCV NS3/4A protease activity in reaction mixtures containing MK-5172, vaniprevir, or the reference compounds danoprevir and TMC435 was determined in a time-resolved fluorescence assay. Cell-based HCV replicon assays were conducted in genotype 1b (con1) stable cell line HB1 (26) or a gt2a cell line (JFH) in the presence of either 10% fetal bovine serum (FBS) or 40% normal human serum (NHS). For in vitro resistance selections, 100,000 HB1 cells were seeded into a T162 Z-top flask and cultured in the presence of 0.5 mg/ml G418 and the desired concentration of MK-5172. Cells were cultured for approximately 3 weeks with regular exchanges of medium until sufficient cell death had occurred to enable distinct colonies to form. After expansion, total RNA was isolated, used as a template to generate NS3/4a cDNA, and sequenced using conventional molecular biology techniques. |
| Cell experiment [1]: | |
Cell lines | A genotype/mutant panel of stable replicon cell lines |
Preparation method | The solubility of this compound in DMSO is >38.4mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reacting condition | 2-10 nM, 3 weeks |
Applications | MK-5172 demonstrated subnanomolar to low-nanomolar EC50s against genotypes 1a, 1b, and 2a. MK-5172 was efficacious across the genetically diverse range of genotype 1 infections encountered in clinical settings with EC50s ranged narrowly between 0.3 and 5.9 nM. In Genotype 1b replicon cells, pre- treatment with MK-5172 resulted in little apparent cell growth and limited recovery of replicon RNA levels. |
| Animal experiment [1]: | |
Animal models | Chimpanzees, Dogs, Rats |
Dosage form | Oral administration, 1 mg/kg, twice daily for 7 days |
Application | MK-5172 demonstrated low to moderate clearance and a modest half-life in both rat and dog. Oral administration of MK-5172 (1 mg/kg) demonstrated modest bioavailability of 12 to 13%, with moderate plasma exposure in both species. The 24-h trough liver concentrations were 0.2 μM in rat and 1.4 μM in dog (1 mg/kg), yielding exposure multiples of 27- to 200-fold over the serum-adjusted replicon EC50. In chronic-HCV-infected chimpanzees harboring gt1a, gt1b, or gt1a NS3 R155K infections, treatment with MK-5172 (1 mg/kg, b.i.d.) demonstrated efficacy in vivo. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

MK-5172 is a selective inhibitor of Hepatitis C Virus NS3/4a Protease [1].Hepatitis C (HCV) virus is a member of the Flaviviridae family of viruses in the Hepacivirus genus and encoded by a 9.6-kb positive strand RNA genome [2].In biochemical assays, MK-5172 inhibited a series of major genotypes and common mutants in a HCV NS3/4A protease enzymatic assay. In a cell-based replicon system, MK-5172 inhibited HCV with EC50 values of 2 nM against genotype 1a, 0.5 nM against genotype 1b, 8 nM against genotype 2a and 13 nM against genotype 3. Also, MK-5172 is effective against HCV genotypes 1a, 2a, 1b, 2b and 3a [2].Treatment three chronically HCV-infected chimpanzees with a dose of 1 mg/kg twice daily for 7 days, Two of the chimpanzees had wild-type (WT) gt1a or gt1b infections with high viral titers (~106 IU/ml). A third chimpanzee had a modest viral titer (~104 IU/ml) that was gt1a NS3 R155K virus. MK-5172 (1 mg/kg) reduced viral titer of the gt1a (WT) infection to ~100 IU/ml within 2 days and the gt1b infection to 20 IU/ml. The gt1a NS3 R155K-infected chimp experienced a rapid ~2-log reduction in viral titer [2]. References:[1]. Harper S, McCauley JA, Rudd MT, et al.

1、光源不同:可见分光光度计的光源一般只用钨灯,而紫外可见分光光度计是用钨灯 氘灯两个光源,同时还多了这两个光源灯的切换部件。这是因为钨灯的光谱范围主要在可见到近红外这段,氘灯主要在紫外端。也正是因为光源的不一样,紫外可见分光光度计也多了一个专门提供氘灯工作的氘灯电源了。
2、光学器件的不同:由于玻璃能吸收紫外波,而对可见到近红外端有比较好的透过性,所以可见分光光度计的一些光学部件可以使用玻璃,而紫外可见分光光度计就不能使用玻璃部件,一般使用石英光学部件。同时由于这个原因,在比色皿的选择上也就有不同了,可见分光光度计可以使用玻璃制的比色皿,而紫外可见分光光度计一般使用石英制的比色皿了。
3、接收器的不同:由于紫外可见分光光度计多了紫外波,所以在接收器的选择上也就不一样了。多了对紫外波的灵敏响应功能,这类接收器的价格就比可见分光光度计的接收器贵了很多了。
分光光度计就是利用分光光度法对物质进行定量定性分析的仪器。
而分光光度法则是通过测定被测物质在特定波长处或一定波长范围内光的吸收度,对该物质进行定性和定量分析。 常用的波长范围为:(1)200~400nm的紫外光区,(2)400~760nm的可见光区,(3)2.5~25μm(按波数计为4000cm<-1>~400cm<-1>)的红外光区。所用仪器为紫外分光光度计、可见光分光光度计(或比色计)、红外分光光度计或原子吸收分光光度计。为保证测量的精密度和准确度,所有仪器应按照国家计量检定规程或本附录规定,定期进行校正检定。 单色光辐射穿过被测物质溶液时,被该物质吸收的量与该物质的浓度和液层的厚度(光路长度)成正比,其关系如下式: 1 A=log — =ECL T 式中 A 为吸收度; T 为透光率; E 为吸收系数,采用的表示方法是(E1% 1cm),即吸收度换算成溶液浓度为1%(g/ml),液层厚度为1cm的数值; C 为100ml溶液中所含被测物质的重量,g(按干燥品或无水物计算); L 为液层厚度 ,cm。 物质对光的选择性吸收波长,以及相应的吸收系数是该物质的物理常数。当已知某纯物质在一定条件下的吸收系数后,可用同样条件将该供试品配成溶液,测定其吸收度,即可由上式计算出供试品中该物质的含量。在可见光区,除某些物质对光有吸收外,很多物质本身并没有吸收,但可在一定条件下加入显色试剂或经过处理使其显色后再测定,故又称比色分析。由于显色时影响呈色深浅的因素较多,且常使用单色光纯度较差的仪器,故测定时应用标准品或对照品同时操作。
分光光度计已经成为现代分子生物实验室常规仪器。常用于核酸,蛋白定量以及细菌生长浓度的定量。
分光光度计的简单原理
分光光度计计采用一个可以产生多个波长的光源,通过系列分光装置,从而产生特定波长的光源,光源透过测试的样品后,部分光源被吸收,计算样品的吸光值,从而转化成样品的浓度。样品的吸光值与样品的浓度成正比。
1,被测液浓度过高造成透过样品的光信号检测不到,这种情况下可以通过稀释样品来完成;
2,测定时,样品室内的样品架在移动时没移动到位造成挡光;
3,仪器内部的光源不亮或光源没有进入单色器中。可以对照以上情况检查分析!
具体应用是使用在:依据朗伯比尔定律(A=kbc)测定物质的吸光度A值,进行定量的目的。
可见分光光度计是有光源(钨丝灯发出连续光谱)、比色皿(装有色溶液)、单色器(给出单色光)、检测器(读出吸光度值)。
2.将灵敏度开关调至“1”档(若零点调节器调不到“0”时,需选用较高档。)
3.根据所需波长转动波长选择钮。
4.将空白液及测定液分别倒入比色杯3/4处,用擦镜纸擦清外壁,放入样品室内,使空白管对准光路。
5.在暗箱盖开启状态下调节零点调节器,使读数盘指针指向t=0处。
6.盖上暗箱盖,调节“100”调节器,使空白管的t=100,指针稳定后逐步拉出样品滑竿,分别读出测定管的光密度值,并记录。
7.比色完毕,关上电源,取出比色皿洗净,样品室用软布或软纸擦净。
①辐射源。必须具有稳定的、有足够输出功率的、能提供仪器使用波段的连续光谱,如钨灯、卤钨灯(波长范围350~2500纳米),氘灯或氢灯(180~460纳米),或可调谐染料激光光源等。
②单色器 。它由入射、出射狭缝、透镜系统和色散元件(棱镜或光栅)组成,是用以产生高纯度单色光束的装置,其功能包括将光源产生的复合光分解为单色光和分出所需的单色光束。
③试样容器,又称吸收池。供盛放试液进行吸光度测量之用,分为石英池和玻璃池两种,前者适用于紫外到可见区,后者只适用于可见区。容器的光程一般为0.5~10厘米。
④检测器,又称光电转换器。常用的有光电管或光电倍增管,后者较前者更灵敏,特别适用于检测较弱的辐射。近年来还使用光导摄像管或光电二极管矩阵作检测器,具有快速扫描的特点。
⑤显示装置。这部分装置发展较快。较高级的光度计,常备有微处理机、荧光屏显示和记录仪等,可将图谱、数据和操作条件都显示出来。
2.将灵敏度开关调至“1”档(若零点调节器调不到“0”时,需选用较高档。)
3.根据所需波长转动波长选择钮。
4.将空白液及测定液分别倒入比色杯3/4处,用擦镜纸擦清外壁,放入样品室内,使空白管对准光路。

6.盖上暗箱盖,调节“100”调节器,使空白管的T=100,指针稳定后逐步拉出样品滑竿,分别读出测定管的光密度值,并记录。
7.比色完毕,关上电源,取出比色皿洗净,样品室用软布或软纸擦净。
1.首先分光光度计使用前要预热15分钟(一般是,设备型号不同可能有所区别)
2.然后注意调零。
3.选取正确的比色皿(包括规格比如1cm,2cm等;还有材质比如玻璃的还是石英的)
4.比色皿外壁擦拭干净且不得有划痕迹最好使用镜头纸进行擦拭
5.检品最好做平行样
可见光的波长范围是400nm~760nm,红620nm--760nm 橙592nm--620nm 黄578nm-- 592nm 绿500nm-- 578nm 青464nm--500nm 蓝446nm --464nm 紫400nm--446nm。
不能用玻璃比色皿是因为紫外线的玻璃的透射能力很低(玻璃吸收紫外光能力强),所以一般采用透射能力强的石英比色皿。
