  Tetrahydro-isoquinoline-Based Factor Xa Inhibitors

  摘要：

  Derivatives of (2-amidino-1,2,3,4-tetrahydro-isoquinolin-7-yloxy)phenylacetic acid (TIPAC) were developed as inhibitors of factor Xa (fXa). The compounds are prepared using 15 synthetic steps on average. The most potent compounds (14, 17, 22-26) display inhibition constants of K-i = 21-55 nM but do not inhibit thrombin (K-i = 5->100 mu M) and only weakly inhibit trypsin (K-i = 0.08-5 mu M). They bear a second basic moiety, e.g., substituted 1-(iminomethyl)piperidines, which is linked to C-4 of the phenyl group of TIPAC via an oxygen atom. The inhibition constants of these compounds are almost independent of the size of the (iminomethyl)piperidine substituent. Due to the fact that fXa displays two cation binding sites, namely, the S1 and S4 sites, in principle two binding modes are conceivable for the novel dibasic fXa inhibitors. Molecular modeling experiments based on the X-ray structures of uninhibited fXa and the DX-9065a/fXa complex were carried out. The results taken together with the inhibition constants clearly favor one binding mode: the tetrahydro-isoquinoline fills the S1 pocket even better than the naphthalene moiety of DX-9065a, and the (iminomethyl)piperidine residues occupy the S4 site.

  Hydroxynitrile lyase (HNL) catalyzed enantioselective CC bond formation is an efficient approach to synthesize chiral cyanohydrins which are important building blocks in the synthesis of a number of fine chemicals, agrochemicals and pharmaceuticals. Immobilization of HNL is known to provide robustness, reusability and in some cases also enhances activity and selectivity. We optimized the preparation

  羟基腈裂解酶（HNL）催化的对映选择性CC键形成是合成手性氰醇的有效方法，手性氰醇是许多精细化学品，农用化学品和药物合成中的重要组成部分。已知HNL的固定可提供鲁棒性，可重复使用性，并且在某些情况下还可以增强活性和选择性。我们通过交联酶聚集体（CLEA）法优化了褐藻（Balospermium montanum HNL）固定化的制备（BmHNL），并通过SEM对其进行了表征。使用CLEA-BmHNL进行了生物催化参数的优化，以从苯甲醛获得最高的％转化率和ee（S）-扁桃腈的ee。优化的反应参数为：反应时间20分钟，7 U CLEA-BmHNL，1.2 mM底物和300 mM柠檬酸盐缓冲液pH 4.2，合成了约99％ee和约60％转化率的（S）-扁桃腈。与其他CLEA-HNL不同，在CLEA-BmHNL生物催化中添加有机溶剂的ee％或产物转化率没有提高。CLEA-BmHNL可以成功地连续使用八

  A new hydroxynitrile lyase (HNL) was isolated from the seed of Japanese apricot (Prunus mume). The enzyme has similar properties with HNL isolated from other Prunus species and is FAD containing enzyme. It accepts a large number of unnatural substrates (benzaldehyde and its variant) for the addition of HCN to produce the corresponding cyanohydrins in excellent optical and chemical yields. A new HPLC

  compounds were tested as activators of dopamine-sensitive adenylate cyclase (a measure of DA-1 agonist activity) and as renal vasodilators. All three O-methyl derivatives were much less potent than 1 in cyclase activation and as renal vasodilators. Weak inhibition of adenyl cyclase was also observed for all three compounds and one showed weak renal vasoconstrictor activity. Preliminary investigation of the

  Ruthenium‐catalyzed dehydrogenation of cyanohydrins under acceptorless and base‐free conditions was demonstrated for the first time in the synthesis of acyl cyanide. As opposed to the thermodynamically preferred elimination of hydrogen cyanide, the dehydrogenation of cyanohydrins could be kinetically controlled with ruthenium (II) bidentate phosphine complexes.
