pyridopyrrolopyrimidine alkaloids, variolin A (2) and N(3′)-methyl tetrahydrovariolin B (3), have been isolated from the Antarctic sponge Kirkpatrickia varialosa, and their structures determined by X-ray crystallography and interpretation of spectral data respectively. N(3′)-Methyl tetrahydrovariolin B (3) is moderately cytotoxic and showed antifungal activity, while variolin A (2) is weakly cytotoxic.
从南极海绵Kirkpatrickia varialosa中分离了两个吡啶并吡咯并嘧啶生物碱,variolin A(2)和N(3')-甲基四氢variolin B(3),并通过X射线晶体学和光谱数据解释分别确定了它们的结构。N(3')-甲基四氢variolin B(3)具有中等细胞毒性,并显示出抗真菌活性,而variolin A(2)具有弱细胞毒性。
