生物活性

製品説明 HPI-4 (Ciliobrevin A, Hedgehog Pathway Inhibitor 4) is a hedgehog (Hh) pathway antagonist. It blocks Sonic hedgehog (Shh)-induced Hh pathway activation (IC50 = 7 μM) downstream of Smo.
in vitro HPI-4 does not directly target Smo. It counteracts the activities of endogenous Gli1 and Gli2 but does not directly act on transcription factor GLIs. HPI-4 significantly inhibited the proliferation of these neuronal progenitors, as measured by histone H3 phosphorylation (pH3) levels, It also reduced cellular levels of cyclin D1 protein and Gli1, Gli2, and N-Myc transcripts in the Cerebellar Granule Neuron Precursors. HPI-4 acts by perturbing ciliogenesis[1]. Treatment with HH pathway inhibitor-4 (HPI-4) could significantly decrease human chondrosarcoma cell proliferation, invasion and migration ability. Furthermore, HPI-4 could distinctly disturb HH pathway-mediated ciliogenesis and suppress primary cilia-related protein intraflagellar transport protein IFT88 expression. HH downstream effect molecular GLI2 was restrained to block parathyroid hormone-related protein and affect MAPK/ERK-regulated matrix metalloproteinases (MMP2 and MMP9)[2]. HPI-4(ciliobrevin A) is also a small molecule inhibitor of the catalytic heavy chain subunit of cytoplasmic dynein.
in vivo Pancreatic fibrosis and destruction were effectively prevented by the treatment of HPI-4, a ciliogenesis inhibitor, in zebrafish model[3].

濃度 0, 5 and 10 μM
反応時間 0, 1, 3, 6 and 9 days
実験の流れ Using MTS-8 assay to measure cell proliferation and the toxicity of this drug. 2000 cells were plated in 96-well plates per well. HPI-4 was added to cells at concentrations of 0, 5 and 10 μM in 100 μl DMEM/F12 with 10% FBS and incubated for 0, 1, 3, 6 and 9 days. Then, 10 μl MST-8 was added to the media in each well and incubated in an environment without light for 90 min. The absorbance value was measured using an enzyme microplate reader at 450 nm wavelength. The relative viability of cells was expressed by OD value.
