| Bioactivity | TR-14035 is a orally active dual α4β7/α4β1 integrin antagonist, with IC50 s of 7 nM and 87 nM for α4β7 and α4β1, respectively. TR-14035 can be used for the research of inflammation and autoimmune diseases[1][2]. | ||||||||||||
| Invitro | TR14035 blocks adhesion of RPMI-8866 cells to MAdCAM-Ig by 100% at 1 μM, with an approximate IC50 of 0.01 μM[2]. | ||||||||||||
| 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].
