包装规格：100mg 1g in glass bottle
产品简介：一种长效的DPP-4抑制剂。 Trelagliptin is a long acting dipeptidyl peptidase-4 (DPP-4) inhibitor that is being developed by Taeda for the treatent of type 2 diabetes (T2D). Once-weely SYR-472 treatent produced clinically and statistically significant iproveents in glycaeic control in patients with type 2 diabetes. It was well tolerated and ight be a new treatent option for patients with this disease. Trelagliptin (Zafate) was approved in Japan for the treatent of type 2 diabetes ellitus.
溶解性：溶于DMSO(≥50mg/mL )

体内实验：1、请依序添加每种溶剂： 10% DMSO→40% PEG300→5% Tween-80→45% Saline Solubility: ≥ 2.5 mg/mL (5.26 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。 以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；再向上述体系中加入 50 μL Tween-80，混合均匀；然后再继续加入 450 μL 生理盐水 定容至 1 mL。 2、请依序添加每种溶剂： 10% DMSO→ 90% (20% SBE-β-CD in Saline) Solubility: ≥ 2.5 mg/mL (5.26 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。 以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中，混合均匀。 2 g SBE-β-CD（磺丁基醚 β-环糊精）粉末定容于 10 mL 的生理盐水中，完全溶解至澄清透明。 3、请依序添加每种溶剂： 10% DMSO→90% Corn Oil Solubility: ≥ 2.5 mg/mL (5.26 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液，此方案实验周期在半个月以上的动物实验酌情使用。 以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中，混合均匀。 4、请依序添加每种溶剂： PBS Solubility: 50 mg/mL (105.16 mM); 澄清溶液; 超声助溶 注：工作液建议您现用现配，当天使用。 ＜1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得，实际溶液度可能与公布值有所偏差，属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液；一旦配成溶液，请分装保存，避免反复冻融造成的产品失效。
靶点：DPP-4
体外研究：Dipeptidyl peptidase-4 (DPP-4) is one of the widely explored novel targets for type 2 diabetes mellitus (T2DM) strategy to preserve the endogenous glucagon like peptide (GLP)-1 activity by inhibiting the DPP-4 action. Trelagliptin exhibits potent inhibitory activity toward DPP-4 prepared from Caco-2 cells with an IC50 value of 5.4 nM. Trelagliptin also inhibits human, dog, and rat plasma DPP-4 activity with IC50 values of 4.2 nM, 6.2 nM, and 9.7 nM, respectively. Trelagliptin is highly selective for DPP-4 and displays IC50 values >100,000 nM corresponding to >10,000-fold selectivity over DPP-2, DPP-8, DPP-9, PEP and FAPα activities. Trelagliptin shows DPP4 selective about 4- and 12-fold more potent than alogliptin and sitagliptin, respectively.
体内研究：Trelagliptin (oral gavage; 7 mg/kg; single dose) shows sustained PD effect in dogs and gives >80% inhibition of DPP-4 activity even after 24h. Trelagliptin (oral gavage; 3 mg/kg; single dose; 60 min prior to oral glucose) significantly improves the glucose tolerance capacity by decreasing the AUC0 120min of 19.3% compared with the vehicle group in ob/ob mice. Trelagliptin (oral gavage; 10 mg/kg; once a week; 8 weeks) caused significant reductions in fasting blood glucose (FBG) levels, and the average reduction during the entire treatment period is 16.8% compared to the control.It also increases insulin level and raised it by 1.7-fold in AUC0 120min in ob/ob mice.
