  摘要：

  乙氧基羰基异硫氰酸酯与氨基脲或硫代氨基脲的相互作用分别产生1-乙氧基羰基-2-硫代双脲或联硫脲。前者可与酸中的2-乙氧基碳酰胺基-5-羟基-1,3,4-噻二唑或2（H）-氨基甲酰基-3-羟基-5-烷硫基1,2,4-三唑环化，因此在碱性介质中生成3-羟基-5-巯基-1,2,4-三唑 1-乙氧基羰基联硫脲的闭环类似地进行，在酸的影响下提供5-氨基（或巯基）-2-乙氧基碳酰胺基-1,3,4-噻二唑。碱的作用产生了衍生自3-羟基-5-巯基-1,2,4-三唑的化合物；在选定的实例中，对2（H）-苯基硫代氨基甲酰基衍生物的分离阐明了该反应的过程。1-乙氧基羰基联硫脲的水合肼解产生4-氨基-3-肼基-5-巯基-1,2,4-三唑。

  Carbonohydrazide and its thio-analogue undergo di-addition with ethoxycarbonyl isothiocyanate. The reaction terminates at the mono-addition stage when one of the hydrazine moieties of the (thio)carbonohydrazide is blocked. The resulting 6-(substiiuted)amino-1-ethoxycarbonyl-thiobiureas and bithioureas are cyclised to the appropriate 1-ethoxycarbonamido-1,3,4-thiadiazoles by acids, and to mercapto-1

  A new series of 1,3,4-thiadiazole-2-thione derivatives have been prepared and assayed for the inhibition of three physiologically relevant carbonic anhydrase (CA, EC 4.2. 1. 1) isozymes, the cytosolic human isozymes I and II, and the transmembrane, tumor-associated hCA IX. Against hCA I the investigated thiones, showed inhibition constants in the range of 2.55-222 mu M, against hCA II in the range of 2.0-433 mu M, and against hCA IX in the range of 1.25-148 mu M. Compound 5c, 4-(4,5-dihydro-5-thioxo-1,3,4thiadi izol-2-yl)-1-(5-nitro-2-oxoindolin-3-ylidene)semicarbazide showed interesting inhibition of the turnor-associated hCA IX with K-1 value of 1.25 mu M, being the first non-sulforiamide type inhibitor of such activity. This result is rather important taking into consideration the known antitumor activity of thiones. In addition, docking of the tested compounds into CA II active site was performed in order to predict the affinity and orientation of these compounds at the isozyme active site. The results showed similar orientation of the target compounds at CA II active site compared with reported sulfonamide type CAls with the thione group acting as a zinc-binding moiety.
