Discovery of Novel Inhibitors of Uridine Diphosphate-N-Acetylenolpyruvylglucosamine Reductase (MurB) from Pseudomonas aeruginosa, an Opportunistic Infectious Agent Causing Death in Cystic Fibrosis Patients
The catalytic enantioselective diorganozinc additions to cyclic diketones including pyrazolin‐4,5‐diones and isatins have been developed. In the presence of morpholine‐containing chiral amino alcohol ligand, the corresponding chiral cyclic tertiary alcohols were produced in good to excellent yields (up to 97 %) and enantioselectivities (up to 95 % ee). The notable feature of this protocol includes
that plays an important role in controlling the regioselectivity in the three rearrangements, further determining the structures of o-semidines, p-semidines, and diphenylines. The current results provide new insights into the o/p-semidine and diphenyline rearrangements and useful information for controlling and predicting the structures of the rearrangement products.
The invention relates to novel 6-arylmethyl-substituted pyrazolopyrimidines, process for their preparation and their use for producing medicaments for improving perception, concentration, learning and/or memory.

environmentally benign compounds with high biological activity, low toxicity and low resistance, 8 novel benzoylhydrazines containing pyrazole were designed and synthesized. All compounds were characterized by 1H NMR spectra and HRMS. The preliminary results of biological activity assessment indicated that most of title compounds exhibited certain insecticidalactivities against Mythimna separata Walker at 200
为了寻找具有高生物活性,低毒性和低抗性的环境友好的化合物,设计并合成了8种新型的含吡唑的苯甲酰肼。所有化合物均通过1 H NMR光谱和HRMS表征。生物活性评估的初步结果表明,大多数标题化合物在200 mg·L -1时具有一定的杀灭Mythimna separata Walker的杀虫活性,但在50 mg·L -1时对六种真菌具有优异的杀真菌活性,优于对照。
