A new azaphilone derivative, named peniazaphilin A (1) and one known isocoumarin, (R)-3-methyl-6-hydroxy-8-methoxy-3,4-dihydroisocoumarin (2) were isolated from the fungus Penicillium sp. CPCC 400786. Their structures were elucidated by means of extensive spectroscopic analysis. The absolute configuration of 2 was established by circular dichroism for the first time. Compounds 1 and 2 exhibited weak anti-HIV activities with the IC values of 60.4 and 69.3 μM, respectively.
从真菌青霉 CPCC 400786 中分离得到一个新的氮杂菲酮衍生物,命名为 peniazaphilin A(1)和一个已知的异香豆素(R)-3-甲基-6-羟基-8-甲氧基-3,4-二氢异香豆素(2)。通过广泛的光谱分析阐明了它们的结构。(2)的绝对构型首次通过圆二色谱确定。化合物 1 和 2 表现出微弱的抗 HIV 活性,IC 值分别为 60.4 和 69.3 μM。
