126-81-8

3218-36-8

1099644-42-4

以对苯基苯甲醛（1 mmol）、5,5-二甲基-1,3-环己二酮（0.14 g，1 mmol）、乙酰乙酸乙酯（0.13 g，1 mmol）、乙酸铵（0.115 g，1.5 mmol）和Fe2O3（催化量）负载于羟基磷灰石（HAP，催化量）上为原料，加入三聚氰胺（0.15 g）作为助剂，在80℃下加热反应。反应进程通过薄层色谱（TLC，展开剂为正己烷/乙酸乙酯，体积比10:3）进行监测。反应完成后，将反应混合物冷却至室温，用热乙酸乙酯洗涤，并通过磁力分离去除催化剂。将固体残余物分离，并通过在热乙醇中重结晶进行纯化，得到目标产物4-([1,1'-联苯]-4-基)-2,7,7-三甲基-5-氧代-1,4,5,6,7,8-六氢喹啉-3-羧酸乙酯。

常见问题列表

生物活性

ITD-1是有效的TGF-β抑制剂。它不抑制TGFBR1或TGFBR的激酶活性，但能够有效地抑制TGFβ2诱导的效应因子SMAD2/3磷酸化，对Activin A的影响甚微。

靶点

Target	Value
TGF-β ()

体外研究

ITD-1 potently blocks phosphorylation of the effector SMAD2/3 proteins induced by TGFβ2, and only minimally in response to Activin A. HEK293T cells are transfected with a Smad4 response element driving luciferase (SBE4-Luc) to test whether ITD-1 blocks Activin A/Nodal and/or TGFβ signaling, which utilize the same intracellular signaling cascade through Smad4. ITD-1 strongly inhibits TGFβ2 signaling with similar efficacy (92% vs. 99% respectively), but with lower potency compared to SB-431542, an ACVR1B/TGFBR1 kinase inhibitor (IC ₅₀ = 850nM vs. 70nM respectively), and is a weak and partial inhibitor of Activin A signals. ITD-1 selectively enhances the differentiation of uncommitted mesoderm to cardiomyocytes, but not to vascular smooth muscle and endothelial cells. ITD-1 reveals an unexpected role for TGFβ signaling in controlling cardiomyocyte differentiation from multipotent cardiovascular precursors .
