CAS No. : 25683-07-2
MCE 国际站:Pyoluteorin
产品活性:Pyoluteorin 是一种抗生素 (antibiotic),可抑制 Oomycete fungi,包括植物病原体 Oomycete fungi,并抑制由该真菌引起的植物病害。 Pyoluteorin 在体外诱导人三阴性乳腺癌 MDA-MB-231 细胞凋亡 (apoptosis)。 Pyoluteorin 可用于人类三阴性乳腺癌的研究。
研究领域:Anti-infection | Apoptosis
作用靶点:Antibiotic | Fungal | Apoptosis
In Vitro: Pyoluteorin is an antifungal compound composed of a bichlorinated pyrrole linked to a resorcinol moiety, were identified within a 24-kb genomic region of Pseudomonas fluorescens Pf-5.
Pyoluteorin has significant cytotoxicity towards MCF-7 (IC50=1.84 μM). Pyoluteorin also displays significantly selective cytotoxicity against BT474, HCC1954, MAD-MB-468, MDA-MB-231, and MCF-10A cells with IC50s of 9.75±0.16, 0.94±0.01, 3.89±0.08, 0.97±0.01, and 57.01±0.76 μM, respectively.
Pyoluteorin (0.1-10 μM; for 24 hours) induces change of apoptosis-related protein expressions. Pyoluteorin-induced cell apoptosis in MDA-MB-231 is related to Bcl-2 family proteins and caspase cascade.
Pyoluteorin (0.1-10 μM; for 24 h) induces cell cycle arrest and apoptosis in human triple-negative breast cancer cells MDA-MB-231.
