T-26c 显着减少 IL-1β 和制瘤素 M 刺激的软骨中胶原蛋白的分解量(0.1 μM 时抑制 87.4%)[1]。
化合物 26c 对人MMP-13催化结构域酶表现出强效抑制活性,IC50为6.9 pM。 在牛鼻软骨外植体实验中,26c 能显著抑制细胞因子诱导的II型胶原片段降解和释放。在0.1 μM浓度下,它对胶原降解的抑制率为87.4%,与广谱MMP抑制剂RS-130,830的效果相当(0.1 μM下抑制率为76.3%)[1] |

口服剂量为 10-20 mg/kg 时,T-26c 在所有物种中均被良好吸收。与游离酸 T-26c(AUC = 6478 ng·h/mL 和 Cmax = 911 ng/mL)相比,口服 T-26c 二钠盐制剂对豚鼠产生显着影响。 AUC (8357 ng h/mL) 和 Cmax (1445 ng/mL) 增加[1]。

使用基于荧光的方法测定对人重组MMPs和TACE的抑制活性。前MMPs在测定缓冲液中用对氨基苯汞乙酸盐预孵育活化。MMP测定缓冲液含50 mM Tris-HCl (pH 7.5)、10 mM CaCl2、150 mM NaCl和0.05% Brij-35。TACE测定缓冲液含25 mM Tris-HCl (pH 9.0)、2.5 mM ZnCl2和0.005% Brij-35。酶抑制实验在含有酶和荧光淬灭肽底物的测定缓冲液中进行。在37°C孵育40分钟后,加入EDTA终止反应。测定荧光增加值,计算酶活性百分比,并通过曲线拟合得到IC50值。[1]

| 动物实验 |
Pharmacokinetic studies of 26c and its disodium salt (43) were conducted in guinea pigs, dogs, and monkeys. For oral administration, the disodium salt formulation (43) was used. In guinea pigs, 26c (free acid) was administered intravenously at 1 mg/kg and orally at 10 mg/kg. The disodium salt (43) was administered orally at 10 mg/kg to guinea pigs, at 10 mg/kg to dogs (both iv and po), and at 20 mg/kg to monkeys (po). Blood samples were collected to determine pharmacokinetic parameters. [1]
A 2-week repeated dose oral toxicity study was performed in rats with the disodium salt 43. [1] |
| 药代性质 (ADME/PK) |
In guinea pigs following a 1 mg/kg intravenous dose of 26c, the volume of distribution at steady state (Vd,ss) was 923 mL/kg, and total body clearance (CL) was 431 mL/h/kg. Oral administration of 26c (10 mg/kg) in guinea pigs resulted in a Cmax of 911 ng/mL, Tmax of 0.83 h, AUC of 4478 ng·h/mL, and an oral bioavailability (F) of 28%.
Oral administration of the disodium salt 43 (10 mg/kg) in guinea pigs gave a Cmax of 1445 ng/mL, Tmax of 0.67 h, and AUC of 8357 ng·h/mL. In dogs, intravenous administration of 43 (10 mg/kg) gave a Vd,ss of 395 mL/kg and CL of 111 mL/h/kg. Oral administration of 43 (10 mg/kg) in dogs resulted in a Cmax of 2438 ng/mL, Tmax of 2.0 h, AUC of 27136 ng·h/mL, and F of 29%. In monkeys, oral administration of 43 (20 mg/kg) resulted in a Cmax of 6607 ng/mL, Tmax of 3.0 h, and AUC of 82360 ng·h/mL. [1] In rats, following a single 1 mg/kg oral cassette dose, 26c showed an AUC of 366 ng·h/mL, Vd,ss of 878 mL/kg (at 0.1 mg/kg iv), and CL of 693 mL/h/kg (at 0.1 mg/kg iv). [1] |
| 毒性/毒理 (Toxicokinetics/TK) |
A 2-week repeated dose oral toxicity study of the disodium salt 43 in rats established a no observed adverse effect level (NOAEL) of 60 mg/kg/day. [1]

| 其他信息 |
26c (thieno[2,3-d]pyrimidine-2-carboxamide bearing a 4-carboxybenzyloxymethyl group at the 5-position) was designed as a highly potent, selective, and orally available MMP-13 inhibitor based on structure-based drug design targeting the S1' pocket and the adjacent S1" hydrophobic specificity pocket of MMP-13. It acts as a non-zinc-chelating inhibitor. The incorporation of the carboxylic acid group on the P1" substituent was intended to form a salt bridge interaction with Lys140 in the S1" pocket, contributing to its high potency and selectivity. The compound was developed for the potential treatment of osteoarthritis. [1]

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) 。
