aspergillin

Gliotoxin 是一种次生代谢产物，由A. fumigatus 分泌，可以抑制巨噬细胞的吞噬作用和其他免疫细胞的免疫功能。它通过阻止 IκB 降解来抑制诱导型NF-κB 活性，从而诱导宿主细胞凋亡。它可以激活PKA 并增加细胞内 cAMP 浓度，调节肌动蛋白细胞骨架重排以促进A. fumigatus 内化到肺上皮细胞。

Aspergillin PZ is a fungal metabolite originally isolated from A. awamori. It induces morphological deformation of P. oryzae conidia when used at a concentration of 89 nM. Aspergillin PZ is active against S. epidermidis (MIC = 20 μM) but not S. aureus, E. coli, or B. cereus (MICs = >20 μM). It is cytotoxic to HL-60 promyelocytic leukemia cells (IC50 = 56.61 μM) but not THP-1 acute monocytic leukemia or PC3 prostate cancer cells (IC50s = >80 μM).
