摘要:在这项研究中,以co2为底物,研究了一些糖精衍生物对纯化碳酸酐酶i和ii的体外抑制作用.结果表明,所有化合物均抑制hca I和hca Ii酶活性.在这些化合物中,发现6-(对-甲苯基硫脲基)糖精(6M)对hca I活性最强(ic50 = 13.67μm),而6-(间-甲氧基苯基脲基)糖精(6B)是最有效的. Hca Ii活性最高的一种(ic50 = 6.54μm).结构活性关系(sars)研究表明,一般而言,硫脲衍生物(6V)比尿素衍生物(6A-K)抑制更多的hca I和hca Ii.所有化合物(不包括6C和6R)对hca Ii的抑制活性均高于对hca I的抑制活性.

摘要:The present invention relates to efficient processes useful in the preparation of fluorinated nucleosides, such as (O—{[(2R,3R,4S,5R)-5-(6-amino-9H-purin-9-yl)-4-fluoro-3-hydroxyoxolan-2-yl]methyl}O,O-dihydrogen phosphorothioate, also known as 2′-(S)-fluoro-thio-adenosine monophosphate or 2′-F-thio-AMP. Such fluorinated nucleosides may be useful as a biologically active compound and or as an intermediate for the synthesis of more complex biologically active compounds. The present invention also encompasses intermediates useful in the disclosed synthetic processes and the methods of their preparation.
