Decaturenol A (1), a new oxalicine related meroterpenoid, has been isolated from Penicillium decaturense RO050 along with seven known compounds (28). The structure of 1 was elucidated by spectroscopic data. The effects of isolated compounds (18) on endoplasmic reticulum (ER) stress-induced cell death in HT22 hippocampal nerve cells and on the interleukin 10 (IL-10)-induced expression of CD163, a M2 phenotype marker, in human monocyte-derived macrophages were evaluated. While decaturenol A (1) exhibited a protective effect on ER stress-induced cell death in HT22 cells at 10 µM, on the other hand oxalicine A (7) showed cytotoxic activity (IC50 = 5.9 µM). Additionally, decaturenol A (1), decaturins D (2), E (3), and B (4) inhibited the IL-10-induced expression of CD163 each at a concentration of 20 µg/mL.

从十度青霉菌RO050中分离得到的Decaturenol A和已知的草酸相关的类萜类化合物及其新的生物学活性。

Decaturenol A(1),一个新的相关oxalicine meroterpenoid,已经从分离青霉decaturense具有七个已知化合物(沿RO050 2 - 8)。通过光谱数据阐明了1的结构。分离的化合物(的影响1 - 8)上的内质网(ER)应激诱导的细胞死亡中海马HT22神经细胞和白细胞介素10(IL-10)CD163,一个M2的表型标记物的诱导表达,在人单核细胞评估了巨噬细胞。十氢萘酚A(1)对ER应激诱导的HT22细胞中10 µM的细胞死亡具有保护作用,而草酸辛酯A(7)显示出细胞毒活性(IC 50  = 5.9 µM)。此外,十全醇A​​(1),十全蛋白D(2),E(3)和B(4)分别以20μg/ mL的浓度抑制IL-10诱导的CD163表达。
