(10) and 2-(3-methoxy-2,2-dimethyl-propyl)-naphthalen-1-ol (13). Compounds 4, 5 and 8 were prepared by methylation of compounds 2, 3 and 7, respectively while compounds 10 and 13 were prepared in good yield from naphthols 2 and 7, respectively. When tested for inhibitory activity, five compounds (2, 3, 7, 10 and 13) showed preferential inhibition of COX-2 over COX-1, while compounds 4, 5 and 8 lacked
萘酚衍生物,2-(3'-羟丙基)-萘-1-醇(2),2-(3'-羟基-2'-甲基丙基)-萘-1-醇(3)和2-(3'-羟基-2',2'-二甲基丙基)-萘-1-醇(7)已被合成,并且已经由我们的小组进行了报道。因此,在本文中,我们描述了其醚衍生物3-(1-甲氧基-萘-2-基)-丙-1-醇(4),3-(1-甲氧基-萘-2-基)-的进一步合成2-甲基-丙-1-醇(5),3-(1-甲氧基-萘-2-基)-2,2-二甲基-丙-1-醇(8),2-(3-甲氧基-丙基)-萘-1-醇(10)和2-(3-甲氧基-2,2-二甲基-丙基)-萘-1-醇(13)。通过分别使化合物2、3和7甲基化来制备化合物4、5和8,而分别从萘酚2和7以高收率制备化合物10和13。测试抑制活性时,发现五种化合物(2、3、7,10和13)显示出对COX-2的抑制作用优于COX-1,而化合物4、5和8对COX-1或COX-2同工酶均没有抑
