| 动物实验 |
Xenograft model establishment: Female nude mice (6-8 weeks old) were subcutaneously injected with 5×106 PC-3 cells (suspended in PBS/matrigel) into the right flank. Treatment was initiated when tumors reached ~100 mm3 [1]
- Drug preparation: NSC 31205 was dissolved in 10% DMSO + 90% polyethylene glycol 400 (PEG400) [1] - Drug administration: Mice were randomly divided into vehicle control and NSC 31205 treatment groups (n=8/group). NSC 31205 was administered via oral gavage at 50 mg/kg once daily for 21 consecutive days; vehicle control mice received the same volume of 10% DMSO + 90% PEG400 [1] - Monitoring and sample collection: Tumor volume was measured every 3 days (volume = length × width² / 2), and body weight was recorded weekly. At the end of treatment, mice were euthanized, tumors were excised and weighed, and a portion of tumor tissue was collected for western blot analysis [1] |

No significant body weight loss (≤5% of initial weight) was observed in NSC 31205-treated mice during the 21-day treatment period [1]
- Gross examination of major organs (liver, kidney, spleen) from NSC 31205-treated mice showed no abnormalities such as hypertrophy or discoloration [1] - Serum levels of alanine transaminase (ALT), aspartate transaminase (AST), blood urea nitrogen (BUN), and creatinine (Cr) in NSC 31205-treated mice were within the normal range, with no significant differences compared to vehicle control [1] - The plasma protein binding rate of NSC 31205 was 89% (determined by ultrafiltration method) [1] |

| 其他信息 |
NSC 31205 is a selective small-molecule inhibitor of PIM-1 protein kinase, acting as a competitive inhibitor by binding to the ATP-binding pocket of PIM-1 [1]
- Its antitumor mechanism involves inhibiting PIM-1-mediated phosphorylation of downstream substrates (STAT3, BAD), thereby blocking tumor cell proliferation signaling pathways and inducing tumor cell apoptosis [1] - The patent discloses NSC 31205 as a potential therapeutic agent for the treatment of PIM-1-overexpressing prostate cancer, and it may also be effective for other tumors driven by dysregulated PIM-1 kinase activity [1] |

| 溶解度 (体内实验) |
配方 1 中的溶解度: ≥ 2.08 mg/mL (8.84 mM) (饱和度未知) in 10% DMSO + 90% Corn Oil (这些助溶剂从左到右依次添加,逐一添加), 澄清溶液。
例如,若需制备1 mL的工作液,可将100 μL 20.8 mg/mL 澄清 DMSO 储备液加入到 900 μL 玉米油中并混合均匀。 请根据您的实验动物和给药方式选择适当的溶解配方/方案: 1、请先配制澄清的储备液(如:用DMSO配置50 或 100 mg/mL母液(储备液)); 2、取适量母液,按从左到右的顺序依次添加助溶剂,澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明,并不一定代表此产品 的实际溶解配方): 10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline); 假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀/澄清;向上述体系中加入50 μL Tween-80,混合均匀/澄清;然后继续加入450 μL ddH2O (或 saline)定容至 1 mL; 3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例; 4、 如产品在配制过程中出现沉淀/析出,可通过加热(≤50℃)或超声的方式助溶; 5、为保证最佳实验结果,工作液请现配现用! 6、如不确定怎么将母液配置成体内动物实验的工作液,请查看说明书或联系我们; 7、 以上所有助溶剂都可在 Invivochem.cn网站购买。 |

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;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
