  Design, Synthesis, and Activity of 2,6-Diphenoxypyridine-Derived Factor Xa Inhibitors

  摘要：

  A novel series of 2,6-diphenoxypyridines has been designed to inhibit factor Xa, a serine protease strategically located in the coagulation cascade. The evolution from the photochemically unstable bisamidine (Z,Z)-BABCH to potent bisamidine compounds with a pyridine heterocycle as the core scaffold has been achieved. The most potent compound in the series, 6h, has a K-i for human factor Xa of 12 nM. The selectivity of 6h against bovine trypsin and human thrombin was greater than 90- and 1000-fold, respectively. Two proposed modes of binding of 6h Do factor Xa are made based on the crystal structures of 6h by itself and of 6h bound to bovine trypsin.

  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.

  本发明涉及一种2-羟基芳酰胺衍生物或其药用可接受的盐，其制备方法，以及作为活性成分的预防或治疗癌症的药物组合物。本发明制备的2-羟基芳酰胺衍生物在抑制TMPRSS4丝氨酸蛋白酶的活性和抑制TMPRSS4表达的癌细胞浸润方面表现出色，因此可以作为一种通过抑制癌细胞中TMPRSS4过度表达的组合物，特别是结肠癌、肺癌、乳腺癌、前列腺癌、卵巢癌、胰腺癌或胃癌细胞的预防或治疗癌症的组合物。

• Sequential C–F activation and borylation of fluoropyridines via intermediate Rh(i) fluoropyridyl complexes: a multinuclear NMR investigation

  DOI：10.1039/b707840d

  日期：——

  The C-F bond activation of fluoropyridines by [Rh(SiPh3)(PMe3)3] afforded Rh(I) fluoropyridyl complexes of the type [Rh(Ar(F))(PMe3)3] with concomitant formation of fluorotriphenylsilane; subsequent treatment with bis-catecholatodiboron yielded fac-[Rh(Bcat)3(PMe3)3] and the free fluoropyridyl boronate esters (Ar(F)Bcat).

  [Rh（SiPh3）（PMe3）3]激活氟吡啶的CF键，得到[Rh（Ar（F））（PMe3）3]类型的Rh（I）氟吡啶基配合物，同时形成氟三苯基硅烷。随后用双儿茶酚二硼烷处理，得到fac- [Rh（Bcat）3（PMe3）3]和游离的氟吡啶基硼酸酯（Ar（F）Bcat）。
