MRT-81 is a potent antagonist of human and rodent smoothened (Smo) receptors, with an IC₅₀ value of 41 nM in the Shh-light2 cells. MRT-81 has potent hedgehog inhibiting activity. MRT-81 can be used for the research of cancer^[1].

IC50: 41 nM (Shh-light2 cells Smo receptors)^[1]

MRT-81 inbihits the differentiation of the mesenchymal pluripotent C3H10T1/2 cells into alkaline phosphatasepositive osteoblasts induced by the Smo agonist SAG (0.1 μM), with an IC₅₀ value of 64 nM^[1].
MRT-81 (1-1000 nM) is a potent antagonist of SAG (0.01 μM)-induced proliferation of rat granule cell precursors (GCPs) with an IC₅₀ less than 10 nM^[1].
MRT-81 (0, 0.1, 1, 10, 30, 100, 300, 1000 nM; 2 h; 37 °C) blocks BODIPY-cyclopamine (5 nM) binding to hSmo in a dose-dependent manner with an IC₅₀ of 63 nM in HEK-hSmo cells^[1].

In Vivo:

请根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液，再依次添加助溶剂：

——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用； 以下溶剂前显示的百
分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

• 1.

  请依序添加每种溶剂： 10% DMSO    90% corn oil

  Solubility: ≥ 2.5 mg/mL (4.50 mM); Clear solution

  此方案可获得 ≥ 2.5 mg/mL (4.50 mM，饱和度未知) 的澄清溶液，此方案不适用于实验周期在半个月以上的实验。

  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。
