In the present study, a novel generation of selective aldose reductase ALR2 inhibitors with significant hypoglycemic activities was designed and modulated based on rhodanine scaffold joined to an acetamidelinker in between two lipophilic moieties. The synthesis of the novel compounds was accomplished throughout simple chemical pathways. Moleculardocking was performed on B-cell membrane protein SUR1
Broadened antibacterial activity was introduced to rhodaninederivatives targeting Mycobacterial tuberculosis enoyl-acyl carrier protein reductase (Mtb InhA) by recruiting feature of xacins to bring DNA Gyrase B inhibitory capability. This is significant for preventing further bacterial injections in the tuberculosis treatment. The most potent compound Cy14 suggested comparable bioactivity (IC50 = 3

The oxidative cyclization of β-Aryl-α-mercaptoacrylic acids with chlorine in dry carbon tetrachloride rapidly gives the corresponding benzo[b]thiophen-2-carboxylicacids in high yield. This process is a considerable improvement on processes previously reported. The purity of the crude β-aryl-α-mercaptoacrylic acids can be determined by titration with iodine in ethanol and thus the crude intermediates
在干燥的四氯化碳中,β-芳基-α-巯基丙烯酸与氯的氧化环化反应可快速生成相应的苯并[ b ]噻吩-2-羧酸。此过程是对先前报告的过程的重大改进。粗β-芳基-α-巯基丙烯酸的纯度可以通过在乙醇中用碘滴定来确定,因此无需使用所计算出的氯气量即可纯化粗中间体,而无需进一步纯化即可将其中间体环化。

novel series of N-aroylated 5-methoxybenzothiophene-2-carboxamides (imides) as potent and selective Clk1/4 inhibitors. Potency of this series was found to be mainly dependent on the presence of an intramolecular H-bond between an ortho-methoxy group and the imide NH, that stabilizes a nearly coplanar conformation of high affinity to the ATP binding pocket(s) of Clk1/4. The two most potent hits in this
