体内研究 (In Vivo) |
研究了三氮唑核苷治疗白化小鼠实验性森林泉脑炎的有效性。研究结果表明,高剂量(200-400 mg/kg)的三氮杂韦林可以适度保护受感染的动物。测试组的动物寿命显着延长(从 4.1 天延长至 4.8 天),并且靶器官中病毒积累量显着下降[3]。

细胞实验 |
与活性药物利巴韦林相比,在敏感细胞培养物中评估了三唑韦林对蜱传脑炎病毒的疗效。在128 mcg/ml的浓度下,三唑韦灵通过在SKEV细胞培养物内积累而对蜱传乙脑病毒繁殖(Sofin株)具有抑制活性[2]。

动物实验 |
The comparative study of the therapeutic efficacy of Triazavirin against experimental Forest-Spring encephalitis on albino mice vs. the active drug Ribavirin® showed that in high doses (200-400 mg/kg) Triazavirin moderately protected the infected animals. A significant increase of the animal lifespan in the test groups (from 4.1 to 4.8 days) and a statistically (p ≤ 0.05) valid decrease of the virus accumulation in the target organ (the brain) were observed[3].

其他信息 |
Triazavirin is a guanine nucleotide analog antiviral originally developed in Russia that has shown efficacy against influenza A and B, including the H5N1 strain. It appears that Triazavirin has shown promise in reducing influenza disease severity and associated complications. Given the similarities between SARS-CoV-2 and H5N1, health officials are investigating Triazavirin as an option to combat SARS-CoV-2, the coronavirus responsible for COVID-19.
Riamilovir is a synthetic guanine derivative, with potential broad-spectrum antiviral activity. Upon administration, riamilovir inhibits viral RNA synthesis, thereby preventing viral transcription and replication. Riamilovir may also bind to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and human angiotensin-converting enzyme 2 (ACE2). This may block the entry of SARS-CoV-2 into human host cells. Drug Indication Triazavirin was developed in Russia as a potential treatment of Influenza A and B infections. Mechanism of Action Triazavirin is a guanosine nucleotide analog that inhibits RNA synthesis. |

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。
