hpi 1

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） .

HPi1 是一种有口服活性的，针对幽门螺杆菌的选择性抗菌剂，IC50为 0.24 μM，MIC 为 0.08-0.16 μg mL。

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)

AM-211 sodium is a novel and potent antagonist of the prostaglandin D2 receptor type 2. AM-211 is active in animal models of allergic inflammation. AM211 has high affinity for human, mouse, rat, and guinea pig DP2 and it shows selectivity over other prostanoid receptors and enzymes. AM211 exhibits good oral bioavailability in rats and dogs and dose-dependently inhibits 13,14-dihydro-15-keto-PGD(2)-induced leukocytosis in a guinea pig pharmacodynamic assay.

HPP-9为一种蛋白降解靶向嵌合体(PROTACs)，基于Hedgehog通路抑制剂(HPI-1)开发，pIC50值为6.71，能够降解BET溴结构域，并表现出抗肿瘤活性[1]。
