The synthesis, tautomerism and antibacterial activity of novel barbiturates is reported. In particular, 3-acyl and 3-carboxamidobarbiturates exhibited antibacterial activity, against susceptible and some resistant Gram-positive strains of particular interest is that these systems possess amenable molecular weight, rotatable bonds and number of proton-donors/acceptors for drug design as well as less

Previous studies demonstrated that anti-hyperlipidemic drug gemfibrozil acts as NO- and heme-independent activator of NO receptor soluble guanylyl cyclase. A series of new gemfibrozil derivatives were synthesized and evaluated for sGC activation. The structure-activity relationship study identified the positions in gemfibrozil's scaffold that are detrimental for sGC activation and those that are amendable
先前的研究表明,抗高血脂药物吉非贝齐可作为 NO 受体可溶性鸟苷酸环化酶的 NO 和血红素非依赖性激活剂。合成了一系列新的吉非罗齐衍生物并评估了 sGC 的活化作用。构效关系研究确定了吉非罗齐支架中不利于 sGC 激活的位置以及可修正以优化修饰的位置。与吉非贝齐相比,化合物7c和15b是纯化 sGC 的 cGMP 形成活性的更有效激活剂,并且表现出预收缩的小鼠胸主动脉环的增强松弛。这些研究建立了进一步改进基于吉非贝齐支架的 sGC 激活剂所需的总体框架。

Trifluoromethyl copper (CuCF3), as a diverse fluorination reagent, has been widely used in trifluoromethylation, perfluoroalkylation, and difluorocarbene reactions. However, it has rarely been reported as a single fluorine source involved in nucleophilic fluorination reactions. This work describes a general strategy involving copper-mediated deoxyfluorination of redox-active esters to rapidly access
