A cell-permeable oxo-tetrahydroquinolinecarboxylate compound that acts as a downstream Hh (Hedgehog) pathway blocker, effectively inhibiting Gli-dependent transcription activity in both Sufu+/+ NIH 3T3 (shh-LIGHT2) and Sufu-/- fibroblast cultures (IC₅₀ = 1.5 & 3 µM, respectively) in a manner similar to two other Hh downstream blockers, HPI-3 (Cat. No. 373276) and GANT-61 (Cat. No. 373401). However, only HPI-1, but not HPI-3 or GANT-61 (no effect at 30 µM), remains effective against Sufu-/- fibroblasts overexpressing Gli1 or Gli2 (IC₅₀ = 6 & 4 µM, respectively). HPI-1 is also shown to inhibit the ligand-independent Hh pathway activation in SmoM2-expressing primary murine CGNPs (Cerebellar Granule Neuron Precursors) and NIH 3T3 (smoM2-LIGHT) cultures.，官网链接：https://www.sigmaaldrich.cn/product/mm/373275 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
