Abstract

Two new benzoic acids, cladoslide A () and cladoslide B (); one new β-carboline derivative, cladospomine (); and one new pyridin-2(1)-one, cladoslide C (), were isolated from the fermentation cultures of the mangrove-derived fungus sp. HNWSW-1, along with the previously reported -acetyl-β-oxotryptamine (), (4,5,11)--cladospolide B (), (4,5,11)--cladospolide B (), and (4,5,11)--cladospolide B (). Their structures were elucidated by spectroscopic analysis, Rh(OCOCF)-induced ECD experiments, and Marfey's method. Compound showed cytotoxicity against the K562 cell line with IC values of 13.10 ± 0.08 M. Moreover, compounds and exhibited inhibitory activity against α-glycosidase with IC values of 0.32 ± 0.01 mM and 0.17 ± 0.01 mM, respectively.

摘要

从源自红树林的真菌Cladosporium sp. HNWSW-1的发酵培养物中分离出两种新的苯甲酸，即枝状滑刃菌素A（）和枝状滑刃菌素B（）；一种新的β-咔啉衍生物，即枝状孢胺（）；以及一种新的吡啶-2(1)-酮，即枝状滑刃菌素C（），同时还分离出了先前报道的N-乙酰基-β-氧代色胺（）、(4,5,11)-三羟基-枝状孢菌素B（）、(4,5,11)-三羟基-枝状孢菌素B（）和(4,5,11)-三羟基-枝状孢菌素B（）。通过光谱分析、Rh(OCOCF3)诱导的ECD实验和马尔菲方法阐明了它们的结构。化合物对K562细胞系显示出细胞毒性，IC50值为13.10±0.08 μM。此外，化合物和对α-糖苷酶表现出抑制活性，IC50值分别为0.32±0.01 mM和0.17±0.01 mM。
