up to 68%. Derivatives containing spiro systems in which carbon C-5 of the thiazole ring is the linker atom were obtained in the presence of N,N-diisopropylethylamine. Some of the obtained compounds, at a concentration of 10 μM have activity in the inhibition of 11β-HSD1 up to 71%. IC50 value for the most active compound: 2-(allylamino)-1-thia-3-azaspiro[4.5]dec-2-en-4-one is 2.5 µM. With a high degree
1β-羟基类固醇脱氢酶1(11β-HSD1)是一种催化非活性可的松转化为生理活性皮质醇的酶。抑制这种酶的活性在治疗库欣氏综合症,代谢综合症和2型糖尿病中起着关键作用。因此,一直在寻找作为该酶的选择性抑制剂的新化合物。 在这项工作中,我们介绍了通过N-烯丙基硫脲与适当的α-溴代酸酯反应合成2-(烯丙基氨基)噻唑-4(5 H)-one衍生物的方法。在使用脂族α-溴酸酯和α-溴-β-苯基酯的情况下,反应在碱性介质(乙醇钠)中进行,分离出产物,产率最高为68%。在N,N-二异丙基乙胺的存在下,获得了含有螺环系统的衍生物,其中噻唑环的碳原子C-5为连接原子。 某些浓度为10μM的化合物在抑制11β-HSD1方面的活性高达71%。最具活性的化合物:2-(烯丙胺基)-1-硫代-3-氮杂螺[4.5]癸-2-烯-4-酮的IC 50值为2.5 µM。由于高度抑制11β-HSD1并在抑制11β-HSD1和11β
