HFI-142 是一种小分子抑制剂,能够特异性结合氨肽酶 N 的活性位点并抑制其酶活性。HFI-142 已被证明可抑制红细胞中白三烯 A4 的生物合成,该作用通过调控与肿瘤生长和进展相关的炎症及代谢通路,可能在癌症研究中具有治疗潜力。HFI-142 还可抑制其他氨肽酶的活性,包括氨肽酶 N 以及与蛋白质代谢相关的多种酶。
M-525 binds to menin (IC50: 3 nM) and achieves low nanomolar potencies in cell growth inhibition and in the suppression of MLL regulated gene expression in MLL leukemia cells. M-525 is a first-in-class, highly potent, irreversible, and covalent menin-MLL
DL-threo dihydrosphingosine is a cell-permeable inhibitor of the extracellular signal-regulated kinase (ERK) signalling cassette in mammalian cells. DL-threo dihydrosphingosine is effective against both growth factor- and G-protein-dependent activation of
KRH102053 is a HIF-1alpha inhibitor. KRH102053 decreased the protein level of HIF-1alpha and the mRNA levels of HIF-regulated downstream target genes, such as vascular endothelial growth factor, aldolase A, enolase 1 and monocarboxylate transporter 4. Consistent with these results, KRH102053 also inhibited the rates of HIF-related migration and invasion of HOS cells as well as the degree of tube formation in human umbilical vein endothelium cells.
