Moracin P exhibits potent in vitro inhibitory activity against hypoxia-induciblefactor (HIF-1), which is a key mediator during adaptation of cancer cells to tumour hypoxia.
HIF-1 alpha (556-574) is a 19-mer fragment of hypoxia-induciblefactor-1, a master regulator of the response to oxygen homeostasis. Hypoxia-induced gene expression is initiated when the HIF-1 subunit is stabilized in response to a lack of oxygen.
Moracin O shows significant neuroprotective, and analgesic activities, it also has a strong protective influence against doxorubicin-induced cardiomyopathy in H9c2 cells with the EC50 value of 4.5 ± 1.3 μM. Moracin O exhibits potent in vitro inhibitory ac
HIF-PHD-IN-1 is a pharmacological compound that acts as an orally active inhibitor of the hypoxia-induciblefactor prolyl hydroxylase domain (HIF-PHD), displaying an IC50 of 54 nM for hHIF-PHD2. Its potential as a therapeutic agent for renal anemia is highly promising.
PRLX-93936 is an analog of erastin that has antitumor activity. It inhibits the hypoxia-induciblefactor 1 (HIF-1) signaling pathway under hypoxic conditions (IC50 = 0.09 μM in a cell-based reporter assay). PRLX-93936 (1 μM) also inhibits hypoxia-induced increases in HIF-1α expression in ME-180 cervical cancer cells. It inhibits the growth of HT-1080 fibrosarcoma, OVCAR-5 ovarian cancer, BJELR tumorigenic primary fibroblast, and PANC-1 pancreatic cancer cells with IC50 values of less than 100 nM. PRLX-93936 inhibits tumor growth in PANC-1 and HT-1080 xenograft models when administered at a dose of 50 mg/kg and induces tumor regression when administered at a dose of 100 mg/kg.
Gramicidin A 是一种从从 B. brevis 分离出来的多肽类抗生素。Gramicidin A 是一种高度疏水的通道形成离子载体,在人工膜中形成一价阳离子可渗透的通道。Gramicidin A 诱导缺氧诱导因子 1α (HIF-1α) 的降解,并能降低人肾细胞癌小鼠异种移植模型的生长。Gramicidin A 具有抗菌、抗疟活性以及溶血活性。
