体外研究 (In Vitro) |
TAK-733 表现出有效的酶活性和细胞活性,针对细胞内持续活性 MEK 酶的 IC50 为 3.2 nM,针对细胞中 ERK 磷酸化的 EC50 为 1.9 nM。使用高达 10 μM 的抑制剂浓度测试的其他激酶、受体和离子通道不受 TAK-733 的影响。 TAK-733 在不同物种中表现出高渗透性和高微粒体稳定性,并且被发现能适度结合血浆蛋白(人类约 97%,小鼠约 96%)。浓度高达 30 μM 时,它不会抑制 P450s[1]。 TAK-733 在大多数黑色素瘤细胞系中表现出广泛的活性,体外相对耐药性 IC50 > 0.1 μM。将 34 种不同的黑色素瘤细胞系与剂量逐渐增加的 TAK-733 一起孵育 72 小时。 34 个细胞系中有 7 个是野生型,27 个具有 BRAFV600E 突变。进行SRB增殖测定,获得的IC50浓度将细胞系分为三组:相对耐药、中等和高度敏感。根据相差至少 10 倍的 IC50[2],指定相对耐药和高度敏感的品系。

体内研究 (In Vivo) |
TAK-733 的药代动力学在裸鼠、大鼠、狗和猴子中进行了检查。所有物种均表现出低清除率和高口服生物利用度。在人类癌症的小鼠异种移植模型中,包括黑色素瘤、结直肠癌、非小细胞肺癌、胰腺癌和乳腺癌模型,TAK-733 表现出广泛的抗肿瘤活性[1]。在植入 A375 细胞的小鼠(5 只/组)中,每天口服 1、3、10 和 30 mg/kg 的 TAK-733,持续 14 天(第 10 至 23 天)会导致肿瘤生长延迟。按照每周 3 天、持续 2 周的间歇给药方案(第 10、13、15、17、20 和 22 天),TAK-733(35、70、100 和 160 mg/kg)也显着抑制肿瘤生长。在每天给予 30 mg/kg TAK-733 的小鼠和间歇性给予 160 mg/kg TAK-733 的小鼠中,观察到三个部分消退 (PR),缓解率为 60%。间歇性给予 70、100 和 160 mg/kg TAK-733 剂量的小鼠也显示出反应、完全消退 (CR) 和部分消退 (PR)。间歇给药方案肿瘤消退率更明显;每天一次 30 mg/kg 剂量下,肿瘤体积最大减少 46.97%,剂量为 160 mg/kg (57.29%)。在每天一次给予 3、10 和 30 mg/kg 剂量或间歇性给予 35、70、100 和 160 mg/kg 剂量的小鼠中,肿瘤生长被显着抑制(%T/C,学生 t 检验,p<0.05)。给药的最后一天[2]。

动物实验 |
Mice: Five to six-week-old female athymic nude mice are used. Using Trypsin-EDTA, cells from mid-log phase cultures are harvested to create A375 human melanoma xenograft tumors. The right flank of 6–8-week-old mice is injected subcutaneously with approximately 5×106 cells suspended in Hanks' balanced salt solution (HBSS). When all of the mice in an experiment have tumors that are between 100 and 200 mm3 in size for antitumor efficacy studies and between 300 and 500 mm3 in size for pharmacodynamic (PD) studies, TAK-733 (1 mg/kg or 10 mg/kg) is started orally[2].

其他信息 |
TAK-733 is a member of the class of pyridopyrimidines that is pyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione substituted by (2R)-2,3-dihydroxypropyl, (2-fluoro-4-iodophenyl)amino, fluoro, and methyl groups at positions 3, 5, 6, and 8, respectively. It is a non-ATP competitive allosteric inhibitor of MEK1/2. It has a role as an EC 2.7.11.24 (mitogen-activated protein kinase) inhibitor, an apoptosis inducer, an antineoplastic agent and an anti-inflammatory agent. It is an organoiodine compound, a pyridopyrimidine, a member of monofluorobenzenes, a substituted aniline, a diol, a secondary alcohol, a primary alcohol and a secondary amino compound.
TAK-733 has been used in trials studying the treatment of Advanced Metastatic Melanoma, Advanced Nonhematologic Malignancies, and Advanced Non-hematologic Malignancies. MEK Inhibitor REC-4881 is an orally bioavailable, non-ATP-competitive, allosteric, small-molecule inhibitor of mitogen-activated protein kinase kinase (MAP2K; MAPK/ERK kinase; MEK) 1 and MEK2, with potential antineoplastic activity. Upon oral administration, MEK inhibitor REC-4881 selectively binds to and inhibits the activity of MEK1/2. This prevents the activation of MEK1/2-dependent effector proteins and transcription factors, which may result in the inhibition of growth factor-mediated cell signaling and tumor cell proliferation. MEK1/2 (MAP2K1/K2) are dual-specificity threonine/tyrosine kinases that play key roles in the activation of the RAS/RAF/MEK/ERK pathway and are often upregulated in a variety of tumor cell types. |

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。
