|
|---|---|
| 体外研究 (In Vitro) |
Vanin-1抑制剂-1(Vanin-1-IN-1)(0.1 nM–50 nM)剂量依赖性抑制重组人Vanin-1酶活性:1 nM剂量抑制率为48%,10 nM剂量达92%,50 nM剂量维持>95%抑制率 [1]
在表达Vanin-1的人肝样细胞(HepG2)中,Vanin-1抑制剂-1(Vanin-1-IN-1)(1 nM–20 nM)剂量依赖性降低泛酰巯基乙胺酶活性(Vanin-1催化活性):10 nM剂量使泛酰巯基乙胺酶活性较对照组降低76% [1] Vanin-1抑制剂-1(Vanin-1-IN-1)对Vanin-1具有高选择性,对相关酶(Vanin-2、Vanin-3)抑制活性极低:Vanin-2和Vanin-3的IC50均>1000 nM [1] 浓度高达100 nM时,Vanin-1抑制剂-1(Vanin-1-IN-1)不影响HepG2细胞活力(活力>90%),MTT法检测证实 [1] |
| 酶活实验 |
Vanin-1酶活性测定:重组人Vanin-1酶与Vanin-1抑制剂-1(Vanin-1-IN-1)(0.01 nM–1000 nM)在含泛酰巯基乙胺(底物)和比色检测试剂的测定缓冲液中孵育,37°C反应60分钟后,检测405 nm处反应产物(半胱胺衍生发色团)的吸光度。相对于对照组计算抑制率,拟合剂量-反应曲线获得IC50值 [1]
选择性测定:重组人Vanin-2和Vanin-3酶采用相同的酶活性测定方案,Vanin-1抑制剂-1(Vanin-1-IN-1)浓度最高达1000 nM,评估脱靶抑制作用 [1] |
| 细胞实验 |

细胞活力测定:HepG2细胞以5 × 10³个细胞/孔接种于96孔板,用Vanin-1抑制剂-1(Vanin-1-IN-1)(0.1 nM–100 nM)处理72小时,加入MTT试剂继续孵育4小时,测定570 nm处吸光度评估细胞活力 [1] |
| 动物实验 |
Acute inflammation mouse model: 6–8 week-old C57BL/6 mice were intraperitoneally injected with lipopolysaccharide (LPS) to induce acute inflammation. One hour prior to LPS injection, mice were randomized into vehicle and Vanin-1-IN-1 treatment groups (5 mg/kg, 10 mg/kg, p.o., n=8/group). Vanin-1-IN-1 was dissolved in 0.5% hydroxypropyl methylcellulose (HPMC) solution. Mice were sacrificed 6 hours post-LPS injection, and liver tissues were collected to measure Vanin-1 enzyme activity and pro-inflammatory cytokine (TNFα, IL-6) levels [1]

In Sprague-Dawley rats, the bioavailability (F) of oral Vanin-1-IN-1 (20 mg/kg) was 51%, the peak plasma concentration (Cmax) was 980 ng/mL, the time to peak concentration (Tmax) was 1.3 h, and the elimination half-life (t1/2) was 7.2 h [1]. In C57BL/6 mice, the Cmax of oral Vanin-1-IN-1 (10 mg/kg) was 650 ng/mL, the Tmax was 1.0 h, and the volume of distribution (Vd) was 285 mL/kg [1]. Vanin-1-IN-1 showed good stability in human liver microsomes (t1/2 = 8.7 h) and mouse liver microsomes (t1/2 = 7.9 h) [1].

| 毒性/毒理 (Toxicokinetics/TK) |
Acute toxicity studies in ICR mice: Oral administration of Vanin-1-IN-1 at doses up to 300 mg/kg did not cause death or significant toxic symptoms (weight loss, diarrhea, behavioral abnormalities) within 14 days [1]. Subchronic toxicity studies in Sprague-Dawley rats (oral administration of 10 mg/kg, 30 mg/kg, and 100 mg/kg daily for 28 days): No significant changes were observed in body weight, hematological parameters (white blood cells, red blood cells, platelets), or biochemical parameters (ALT, AST, BUN, creatinine). Histopathological examination of the liver, kidneys, heart, and lungs revealed no drug-related lesions [1].

| 其他信息 |
Vanin-1-IN-1 is a novel small-molecule Vanin-1 enzyme inhibitor belonging to the pyrimidine carboxamide class of compounds [1]. Its mechanism of action involves selectively inhibiting the activity of Vanin-1 pantothenic acid thioacetylaminease, thereby reducing the production of cysteine (a pro-inflammatory mediator) and the subsequent release of pro-inflammatory cytokines [1]. This compound is being developed for the treatment of Vanin-1-mediated inflammatory diseases, including acute inflammation, liver inflammation, and autoimmune diseases [1]. Vanin-1-IN-1 exhibits good oral bioavailability, metabolic stability, and low toxicity, supporting its potential clinical application [1].

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;
