Rodent models
Rat PCA model (Sprague-Dawley rats, [1]): Rats were intradermally injected with anti-DNP IgE (1 μg/site) on ears. 24 hours later, rats received RN486 (10 mg/kg/day, oral gavage) for 7 days, then challenged with DNP-BSA (1 mg/mL) via tail vein. Ear swelling was measured via caliper; skin histamine was quantified via HPLC. Drug was dissolved in 0.5% methylcellulose + 0.2% Tween 80 [1] - Mouse CIA model (C57BL/6 mice, [1]): Arthritis was induced by intradermal injection of bovine type II collagen (200 μg/mouse). 14 days post-induction, mice received RN486 (25 mg/kg/day, oral gavage) for 21 days. Drug was dissolved in 0.5% methylcellulose; arthritis score (0-10, based on joint redness/swelling) was recorded every 3 days [1] - NZB×NZW lupus model ([3]): 12-week-old female NZB×NZW mice were randomized to vehicle or RN486 groups. RN486 (20 mg/kg/day, oral gavage) was administered for 12 weeks. Drug was dissolved in 0.5% methylcellulose; proteinuria was measured weekly via urine dipstick; serum anti-dsDNA antibodies were detected via ELISA at study end [3] |

RN486 is a selective, reversible Bruton Tyrosine Kinase (BTK) inhibitor that blocks BTK activation by competing with ATP for binding to the kinase active site [1]
- Its therapeutic potential spans B-cell-mediated autoimmune diseases, including allergic hypersensitivity, rheumatoid arthritis, and lupus nephritis, via inhibiting B-cell activation, platelet inflammatory responses, and glomerular inflammation [1][2][3] - Preclinical data confirm its ability to reduce autoantibody production (e.g., anti-dsDNA) and organ damage (e.g., glomerular sclerosis) in lupus models, supporting its role in treating systemic autoimmune disorders [3] |

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。
