从深海真菌灰黄青霉(PenicilliumgriseofulvumMCCC 3A 00225)中分离得到10个新化合物(1-10)和26个已知化合物(11-36)。新化合物的结构通过详细的NMR和HRESIMS光谱数据分析确定。通过X-射线晶体学、Marveland方法和ICD方法建立了绝对构型。在免疫球蛋白(IG)E介导的大鼠嗜碱性白血病(RBL)-2H3细胞中测试所有分离物的体外抗食物过敏生物活性。化合物13显著降低了脱颗粒释放,其IC 50值为60.3 μM,而阳性对照氯雷他定的IC 50值为91.6 μM。
Ten new (1–10) and 26 known (11–36) compounds were isolated from Penicillium griseofulvum MCCC 3A00225, a deep sea-derived fungus. The structures of the new compounds were determined by detailed analysis of the NMR and HRESIMS spectroscopic data. The absolute configurations were established by X-ray crystallography, Marfey’s method, and the ICD method. All isolates were tested for in vitro anti-food allergic bioactivities in immunoglobulin (Ig) E-mediated rat basophilic leukemia (RBL)-2H3 cells. Compound 13 significantly decreased the degranulation release with an IC50 value of 60.3 μM, compared to that of 91.6 μM of the positive control, loratadine.
