In the course of searching for selective growth inhibitors of the cancer cells adapted to nutrient starvation, a new 3-alkylpyridine alkaloid named N-methylniphatyne A (1) was isolated from an Indonesian marine sponge of Xestospongia sp. The chemical structure of 1 was determined on the basis of the spectroscopic analysis and comparison with the synthesized 1 and its analogues. Compound 1 showed the
在寻找适合营养缺乏的癌细胞的选择性生长抑制剂的过程中,从印尼海洋海绵Xestospongia sp。分离出了一种新的3-烷基吡啶生物碱,名为N-methylniphatyne A(1)。1的化学结构是在光谱分析的基础上确定的,并与合成的1及其类似物进行比较。在葡萄糖饥饿的条件下,化合物1对PANC-1细胞具有细胞毒活性,IC50值为16 microM,而在一般培养条件下,直至100 microM都未观察到生长抑制作用。
