5 μM respectively. Compound 8v is a competitive inhibitor with respect to pyruvate (Ki = 0.74 μM) and a mixed-type inhibitor with respect to ATP, indicating that it targets the unique carboxyltransferase (CT) domain of PC. Furthermore, compound 8v does not significantly inhibit human carbonic anhydrase II, matrix metalloproteinase-2, malate dehydrogenase or lactatedehydrogenase.
通过基于结构的药物设计项目(SBDD),发现了有效的丙酮酸羧化酶小分子抑制剂(PC)。制备了一系列α-酮酸(7)和α-羟基肉桂酸(8),并在两种测定中评估了其对PC的抑制作用。两种最有效的抑制剂是3,3'-(1,4-亚苯基)双[2-羟基-2-丙酸](8u)和2-羟基-3-(喹啉-2-基)丙酸(8v))的IC 50值分别为3.0±1.0μM和4.3±1.5μM。化合物8v是相对于丙酮酸(K i = 0.74μM)和针对ATP的混合型抑制剂,表明它靶向PC的独特羧基转移酶(CT)域。此外,化合物8v不会显着抑制人碳酸酐酶II,基质金属蛋白酶-2,苹果酸脱氢酶或乳酸脱氢酶。

A silver‐catalyzed1,3‐dipolarcycloaddition of fluorinated azomethine ylides and activated olefins is reported. The reaction offers a straightforward and atom‐economical procedure for the preparation of fluorinated pyrrolidines. Broad scope and high levels of diastereoselectivity have been achieved simply by using AgOAc/PPh3 as the catalyst system. The high efficiency of the cycloaddition relies on
Intramolecular [2+2] cycloaddition of γ,δ-unsaturated ketenes derived from hex-5-enoyl chloride derivatives gave bicyclo[2.1.1]hexan-5-ones with complete regioselectivity.

Olefin metathesis (OM) is a reliable and practical synthetic methodology for challenging carbon–carbon bond formations. While existing catalysts can effect many of these transformations, the synthesis and development of new catalysts is essential to increase the application breadth of OM and to achieve improved catalyst activity. The unexpected initial discovery of a novel olefin metathesis catalyst
