The present invention relates to a 2-hydroxyarylamide derivative or a pharmaceutically acceptable salt thereof, a preparation method thereof, and a pharmaceutical composition for preventing or treating cancer comprising the same as an active ingredient. The 2-hydroxyarylamide derivative prepared by the present invention is excellent in the inhibition of the activity of TMPRSS4 serine protease and the suppression of the infiltration of TMPRSS4-expressed cancer cells, and thus can be useful as a composition for preventing or treating cancer by inhibiting TMPRSS4 over-expressed in cancer cells, particularly, colorectal cancer, lung cancer, breast cancer, prostate cancer, ovarian cancer, pancreatic cancer, or stomach cancer cells.

Three furanosesquiterpenes, the new tsitsikammafuran (1) and the known nakafurans-8 (2) and -9 (3) were isolated from a South African Dysideasponge. The structure of tsitsikammafuran, initially proposed as 3-[(furan-3-yl)methyl]-p-cymene, from a combination of biosynthetic arguments and the available spectroscopic data, was unequivocally confirmed by the synthesis of 1 from thymol. The synthesis of
从南非Dysidea海绵中分离出三种呋喃倍半萜,新的tsitsikammafuran(1)和已知的nakafurans-8(2)和-9(3)。由百里香酚合成1明确地证实了从生物合成论点和可用光谱数据的组合出发,最初被提议为3-[(呋喃-3-基)甲基]-对-异丙基的tsitsikammafuran的结构。tsitsikammafuran的两种区域异构体,4的合成- [(呋喃-3-基)甲基] -米-cymene(4)和2 - [(呋喃-3-基)甲基] - p -cymene(22),从p-甲酚和2-溴-2-硝基樟脑分别进一步支持1的结构分配。
