Abstract

Four known prenylated flavonoids, artonins E (1) and O (2), artobiloxanthone (3), and cycloartobiloxanthone (4), were isolated from the stem bark of Artocarpus kemando by bioassay-guided fractionation using the DNA strand-scission and the KB cytotoxicity assays as monitors. Compounds 1 and 3 exhibited strong DNA strand-scission activity, and all four compounds were found to be cytotoxic.

摘要

通过以DNA链断裂和KB细胞毒性试验为监测指标的生物活性导向分离法，从白桂木的茎皮中分离出4种已知的异戊烯基黄酮类化合物，即雅顿宁E（1）、雅顿宁O（2）、白桂木氧杂蒽酮（3）和环白桂木氧杂蒽酮（4）。化合物1和3表现出较强的DNA链断裂活性，且发现所有4种化合物均具有细胞毒性。
