从海洋样品中分离得到的詹氏青霉(Penicilliumjanczewskii)中,合成了两个新的非对映体喹啉酮化合物,3S*,4 R *-二羟基-4-(4 '-甲氧基苯基)-3,4-二氢-2(1H)-喹啉酮(1)和3R*,4 R *-二羟基-4-(4-甲氧基苯基)-3,4-二氢-2(1H)-喹啉酮(1)。(4 ′-甲氧基苯基)-3,4-二氢-2(1H)-喹啉酮(2),沿着两种已知生物碱,3)和3-甲氧基-4-羟基-4-(4 ′-甲氧基苯基)-3,4-二氢-2(1H)-喹啉酮(4)。对8种肿瘤细胞系的细胞毒性试验显示,对SKOV-3细胞的中度特异性为2。
From Penicillium janczewskii, obtained from a marine sample, two new diastereomeric quinolinones, 3S*,4R*-dihydroxy-4-(4 '-methoxyphenyl)-3,4-dihydro-2(1H)-quinolinone (1) and 3R*,4R*-dihydroxy-4-(4 ' methoxyphenyl)-3,4-dihydro-2(1H)-quinolinone (2), were identified, along with two known alkaloids, peniprequinolone (3) and 3-methoxy-4-hydroxy-4-(4 '-methoxyphenyl)-3,4-dihydro-2(1H)-quinolinone (4). Cytotoxicity testing on eight tumor cell lines revealed a moderate specificity of 2 on SKOV-3 cells.
