TR-14035 是一种具有口服活性的 α4β7/α4β1整合素 (α4β7/α4β1integrin) 双重抑制剂,对 α4β7和 α4β1作用的IC50值分别为 7 nM 和 87 nM。TR-14035 可用于炎症和自体免疫疾病的研究。
生物活性 | TR-14035 is a orally active dualα4β7/α4β1integrinantagonist, withIC50s of 7 nM and 87 nM for α4β7and α4β1, respectively. TR-14035 can be used for the research of inflammation and autoimmune diseases[1][2]. |
IC50& Target[1] | α4β7 7 nM (IC50) | α4β1 87 nM (IC50) |

体内研究 (In Vivo) | TR-14035 (3 mg/kg; i.g.) produces a significant decrease of the airways hyper-responsiveness to 5-hydroxytryptamine (5-HT) in an experimental model of allergic asthma in Brown Norway rats[3]. TR-14035 exhibits moderate oral bioavailability (rat 17.1%, dog 13.2%) and Cmax(rat 0.18, dog 0.10 μg eq./mL) following oral administration (rat 10 and dog 10 mg/kg)[4]. TR-14035 exhibits terminal elimination half-lives (rat 0.28 h and, dog 0.81 h) due to high plasma clearance (3865 and 1664 mL/h/kg respectively) following intravenous administration (rat 3 mg/kg and dog 3 mg/kg)[4].
Animal Model: | Male Brown Norway rats (250-300 g)[3] | Dosage: | 3 mg/kg | Administration: | Oral gavage, 1 h before and 3 h after antigen challenge | Result: | Suppressed antigen-induced airway hyper-responsiveness and inflammation. |
Animal Model: | Male Sprague-Dawley rats (250-320 g)[4] | Dosage: | 3 mg/ kg for i.v.; 10 mg/kg for oral (Pharmacokinetic Analysis) | Administration: | Intravenous injection and oral administration | Result: | Oral bioavailability (17.1%), Cmax(0.18 μg eq./mL), T1/2(0.28 h). |
Animal Model: | Male beagle dogs[4] | Dosage: | 3 mg/kg for i.v.; 10 mg/kg for oral (Pharmacokinetic Analysis) | Administration: | Intravenous administration and oral administration | Result: | Oral bioavailability (13.2%), Cmax( 0.10 μg eq./mL), T1/2(0.81 h). |
