Synthesis of 3-Aminopyridin-2(1H)-Ones and 1H-Pyrido[2,3-b][1,4]Oxazin-2(3H)-Ones
摘要:
The interaction of 1,3-diketones with chloroacetamide produced N-(3-oxoalkenyl)chloroacetamides. Heating of N-(3-oxoalkenyl)chloroacetamides with an excess of pyridine in ethanol or butanol led to the formation of pyridin-2(1De)-ones, substituted with a pyridine ring at position 3. The reactions of these compounds with hydrazine hydrate produced 3-aminopyridin-2(1De)-ones. The synthesis of 1H-pyrido[2,3-b][1, 4]oxazin-2(3H)-ones was accomplished by a reaction of 3-aminopyridin-2(1De)-ones with chloroacetyl chloride.

A series of nonnucleoside 3-aminopyridin-2(1H)-one derivatives was synthesized and evaluated for HIV-1 RT inhibitory properties. Several analogs proved to be potent and highly selective antagonists with in vitro IC50 values as low as 19 nM in the enzyme assay using rC.dG as template-primer. Two compounds from this series, 3-[[(4,7-dimethylbenzoxazol-2-yl)methyl]-amino]-5-ethyl-6-methy lpyridin-2(1H)-one

inhibitors of α-amylase and α-glucosidase is increasing. In this work, we attempted to carry out studies on the synthesis, modification and comprehensive computer and biologicalresearch of new derivatives of monothiooxamides. It was shown that monothiooxamides based on 3-aminopyridin-2(1H)-ones enter into transamidation reactions with hydrazine hydrate to form the corresponding thiohydrazides. Furthermore
由于全世界糖尿病发病率的增加,寻找新的安全有效的α-淀粉酶和α-葡萄糖苷酶抑制剂的紧迫性越来越大。在本工作中,我们尝试开展单硫代草酰胺新衍生物的合成、修饰及综合计算机和生物学研究。结果表明,基于 3-氨基吡啶-2(1 H ) 的单硫代草酰胺)-ones 与水合肼发生转酰胺基反应,形成相应的硫代酰肼。此外,在氯乙酰氯和琥珀酸酐的作用下,这些硫代酰肼环化成共轭的1,3,4-噻二唑衍生物。使用AutoDock Vina程序通过分子对接评估所得产物可能的生物活性。与已知的抗糖尿病药物阿卡波糖和 TAK-875 相比,化合物7a和8b对选定的靶蛋白显示出更高的结合亲和力。获得的 1,3,4-噻二唑新衍生物在体外试验中对 α-淀粉酶和 α-葡萄糖苷酶具有足够高的抑制活性值以及足够低的 IC 50值(8b 122.2 μM),比参考药物阿卡波糖的值(998.3 μM)小 8 倍。在人类新生儿真皮成纤维细胞的
