| 动物实验 |
Animal/Disease Models: Female balb/c (Bagg ALBino) mouse (6-8 weeks old) are immunized with ovalbumin[3]
Doses: 100 mg/ kg Route of Administration: Po one time/day for 21 days Experimental Results: decreased the number of total cells and eosinophils. Almost completely inhibited the development of antigen-induced bronchial hyperresponsiveness (BHR). diminished the levels of IL-4, IL-5 and IL- 13. Mouse OVA-induced asthma model: 6-week-old BALB/c mice were sensitized with OVA + aluminum hydroxide by intraperitoneal injection on days 0 and 7. From day 14 to 27, mice were challenged with OVA aerosol (1% OVA in saline) for 30 minutes daily. Suplatast Tosylate (IPD 1151T) was suspended in 0.5% carboxymethylcellulose and administered orally at 100 or 300 mg/kg/day from day 14 to 27. On day 28, mice were euthanized; BALF was collected for cell counting, serum for OVA-specific IgE detection, and lungs for histological analysis [2] - Mouse splenocyte co-stimulatory molecule regulation model: 8-week-old C57BL/6 mice were administered Suplatast Tosylate (IPD 1151T) (300 mg/kg/day) orally for 7 days. Splenocytes were isolated, and CD80/CD86 expression was analyzed by flow cytometry. Control mice received vehicle alone [3] - Mouse bleomycin-induced pulmonary fibrosis model: 8-week-old C57BL/6 mice were anesthetized and administered bleomycin (3.5 U/kg) via intratracheal injection. Suplatast Tosylate (IPD 1151T) (300 mg/kg/day) was given orally from day 1 to 21 post-bleomycin. On day 21, mice were euthanized; lungs were collected for hydroxyproline assay, collagen staining (Masson's trichrome), and TGF-β1 mRNA quantification by RT-PCR [4] |
| 毒性/毒理 (Toxicokinetics/TK) |
In vitro cytotoxicity: No significant toxicity to human PBMCs or mouse splenocytes at concentrations up to 200 μg/mL [1, 3]
- In vivo toxicity: No obvious adverse effects (weight loss, behavioral abnormalities) in mice at doses up to 300 mg/kg/day for 21 days. Serum ALT, AST, and creatinine levels were not significantly different from vehicle control [2, 4] - Human clinical tolerance: No severe adverse events reported in preliminary studies; mild gastrointestinal discomfort (≤5% of subjects) was transient [1] |

| 其他信息 |
Suplatast Tosylate (IPD 1151T) is a novel dimethylsulfonium agent with anti-allergic and anti-inflammatory activities [1, 2, 3, 4]
- Its core mechanisms involve: 1) Inhibiting IgE synthesis by B cells via regulating IL-4/IFN-γ balance; 2) Suppressing co-stimulatory molecule (CD80/CD86) expression to attenuate T cell activation; 3) Inhibiting pro-fibrotic cytokine (TGF-β1) to prevent tissue fibrosis [1, 3, 4] - Potential therapeutic indications include allergic asthma, allergic rhinitis, atopic dermatitis, and pulmonary fibrosis [2, 4] - Exhibits oral bioavailability and long-term tolerability, making it suitable for chronic inflammatory/allergic disease management [2, 4] - Differs from conventional antihistamines by targeting the root cause of allergy (IgE production and immune cell activation) rather than symptom relief [1, 2] |

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。
