gli 1

GLI1-IN-1 (CBC-1)，一种GLI-1抑制剂，展现出优异的水溶性及抗癌特性。该化合物能通过抑制Hedgehog (HH) 通路 (IC50=1.3 μM) 来阻止结直肠癌的生长，并能诱导细胞凋亡 (apoptosis)。

GANT 61 (GANT61) 是一种Gli1和Gli2抑制剂，靶向Hedgehog GLi 通路。

RU-SKI 43 是一种有效的选择性刺猬酰基转移酶 (Hhat) 抑制剂，IC50 为 850 nM。RU-SKI 43 具有抗癌活性，是治疗肺腺癌的潜在化合物。RU-SKI 43 通过独立于平滑化的非规范信号传导降低 Gli-1 激活，并抑制 Akt 和 mTOR 通路活性。

HPI 1 是一种刺猬 (Hh) 信号抑制剂。在 Shh-LIGHT2 细胞中抑制 Sonic Hedgehog (Shh)-、SAG- 和 Gli 诱导的 Hh 通路激活（Shh-、SAG-、Gli2- 和 Gli1 诱导的激活的 IC50 值为 1.5、1.5、4 和 6 μM） .

IHR-1 是一种Smo 拮抗剂，不能透过细胞膜。

HPI-1 (hydrate) is a Hedgehog (Hh) pathway inhibitor that suppresses signaling through Sonic Hh (IC50= 1.5 μM) without significantly affecting Wnt signaling (IC50≥ 30 μM).1HPI-1 suppresses Hh activation induced by loss of Suppressor of Fused or by Gli overexpression, suggesting action at posttranslational modification of Gli protein or at the interaction of Gli with a co-factor.1HPI-1 (hydrate) also inhibits signaling through the oncogenic Smoothened (Smo) mutant SmoM2 in neuron precursors, preventing cell proliferation.1 1.Hyman, J.M., Firestone, A.J., Heine, V.M., et al.Small-molecule inhibitors reveal multiple strategies for Hedgehog pathway blockadeProceedings of the National Academy of Sciences of the United States of America106(33)14132-14137(2009)

Darinaparsin is a dimethylated arsenic linked to glutathione. It is cytotoxic to DU145, LNCaP, and PC3 prostate cancer cells (IC50s = 5-10 µM) and patient-derived primary prostate cancer cells (IC50s = 2.5-20 µM), as well as Jurkat T cell lymphoma and L540 Hodgkin lymphoma cells (IC50s = 2.7 and 1.3 µM, respectively). [1][2] It decreases the tumor-initiating subpopulation in DU145 and PC3 cells and halts the cell cycle in the G2 M phase. Darinaparsin decreases transcription of Gli-2, a transcription factor that mediates Sonic hedgehog signaling, when used at a concentration of 1.5 but not 3 µM. It decreases SHP1 phosphatase activity and increases ERK phosphorylation. [2] Darinaparsin reduces tumor growth in DU145 and PC3 prostate cancer mouse xenograft models when administered at a dose of 100 mg kg every other day.[1]
