Animal/Disease Models: 6weeks old female nude mice injected GBM cells[2]
Doses: 20 mg /kg/d Route of Administration: Iv injection Experimental Results: Increased the survival of xenograft mice models. TMZ-resistant glioblastoma xenograft model [2]: Female nude mice (6–7 weeks old) were subcutaneously injected with 5×10⁶ U87-MG (TMZ-resistant) cells (mixed with Matrigel, 1:1 v/v) into the right flank. When tumors reached 100–150 mm³, mice were randomized to 4 groups (n=6/group): 1. Vehicle: 5% DMSO + 45% PEG400 + 50% saline (i.p.) + 0.5% CMC (oral); 2. Hesperadin: 20 mg/kg (i.p., daily); 3. TMZ: 10 mg/kg (oral, daily); 4. Combination: Hesperadin + TMZ (same doses/routes). Treatment lasted 21 days; tumor volume (length×width²/2) and body weight were measured twice weekly [2] - Influenza virus mouse model [3]: BALB/c mice (6–8 weeks old) were anesthetized and intranasally infected with H1N1 influenza virus (100 TCID₅₀ in 50 μL saline). One day post-infection, mice were randomized to 2 groups (n=8/group): 1. Vehicle: 50 μL saline (intranasal, daily); 2. Hesperadin: 5 mg/kg in 50 μL saline (intranasal, daily). Treatment lasted 5 days; mice were euthanized on day 6, and lung tissues were collected for viral titer (TCID₅₀) and histopathology [3] |
| 毒性/毒理 (Toxicokinetics/TK) |
Acute toxicity in mice (influenza model) [3]:
Single intranasal administration of Hesperadin up to 10 mg/kg did not cause mortality or weight loss (<3% change vs. control). No signs of respiratory irritation (e.g., sneezing, labored breathing) were observed [3]
- Chronic toxicity in rats (glioblastoma-related) [2]: Male rats treated with Hesperadin (20 mg/kg i.p., daily for 28 days) showed mild myelosuppression: white blood cell count decreased by 18% vs. control, but red blood cell/platelet counts and serum liver (ALT/AST)/kidney (BUN/creatinine) markers remained normal. No histopathological lesions were found in liver, kidney, or brain [2] - Toxicity to T. brucei vs. mammalian cells [1]: Hesperadin was 10-fold more toxic to T. brucei (IC₅₀ = 200 nM) than to human foreskin fibroblasts (IC₅₀ = 2000 nM), indicating parasite selectivity [1] |

| 其他信息 |
Hesperadin is an oxindole that is indolin-2-one which is substituted at position 5 by an (ethylsulfonyl)nitrilo group and at position 2 by a methylidene group, which is itself substituted by a phenyl group and a [4-(piperidin-1-ylmethyl)phenyl]amino group. An Aurora B kinase inhibitor, it is used to inhibit chromosome alignment and segregation. It has a role as an Aurora kinase inhibitor. It is a member of oxindoles, a member of piperidines, a sulfonamide, an enamine and a tertiary amino compound.
Mechanism in T. brucei [1]: Hesperadin targets TbAUK1 (a key regulator of T. brucei mitotic spindle assembly), disrupting nuclear division and parasite proliferation—identifying TbAUK1 as a novel therapeutic target for African trypanosomiasis [1] - Mechanism in glioblastoma [2]: Synergy with TMZ involves two pathways: (1) Hesperadin inhibits Aurora B, inducing mitotic arrest and apoptosis; (2) it downregulates ABCG2, reducing TMZ efflux and increasing intracellular drug accumulation [2] - Mechanism in influenza [3]: Antiviral activity is host-dependent: Hesperadin inhibits Aurora B, which is required for influenza virus nuclear export (via regulating host CRM1-mediated transport). This avoids viral resistance (no direct viral targeting) [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。
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;
