Four new flavonoids, artoheteroids A-D (1-4), together with six known ones (5-10), were isolated from the roots of Artocarpus heterophyllus. Their structures were elucidated by spectroscopic methods, including 1D and 2D NMR, UV, IR, CD, and HR-ESI-MS. All isolated compounds were screened for their inhibitory abilities against cathepsin K (CatK). Among them, compounds 1-2, 4-6, and 10 were found to have suppression capabilities against CatK with IC values ranging from 1.4 to 93.9μM.
从菠萝蜜的根部分离出四种新的黄酮类化合物,即菠萝蜜异黄酮A-D(1-4),以及六种已知的化合物(5-10)。通过光谱方法,包括一维和二维核磁共振、紫外、红外、圆二色和高分辨电喷雾电离质谱对它们的结构进行了鉴定。对所有分离出的化合物进行了组织蛋白酶K(CatK)抑制能力的筛选。其中,发现化合物1-2、4-6和10对CatK具有抑制能力,其半数抑制浓度值在1.4至93.9μM之间。
