从南中国海绵中分离得到一个新的倍半萜对苯二酚--19-羟基-聚纤维海绵B(1),以及5个已知化合物:聚纤维海绵B(2)、异非正构体对苯二酚(3)、利马喹酮(4)、司米松碱(5)和苦参碱(6)。通过广泛的光谱分析确定了其结构。对HIV-1RT进行体外抗HIV活性评价。化合物3-6表现出中等的抑制活性,其IC50值分别为239.7、16.4、176.1和130.4µM,而化合物1和2对同一生物靶标没有活性。
Detailed chemical investigation of the South China sponge Dysidea arenaria resulted in the isolation of a new sesquiterpenoid hydroquinone, 19-hydroxy-polyfibrospongol B (1), along with five known compounds: polyfibrospongol B (2), isosemnonorthoquinone (3), ilimaquinone (4), smenospongine (5) and smenotronic acid (6). The structures were determined by extensive spectroscopic analysis. The in vitro anti-HIV activity on HIV-1 RT was evaluated. Compounds 3-6 displayed moderate inhibitory activity, with IC50 values of 239.7, 16.4, 176.1, and 130.4 µM, respectively, while 1 and 2 were found to be inactive against the same biological target.
