The Heck reaction of β-arylacrylamides with aryl iodides afforded the corresponding vinylic substitution products usually in high yields. The nature of β-substituents, aryl iodides and substituents at the nitrogen atom influences the stereochemical outcome. N,N-Dimethyl-β-arylacrylamides gave vinylic substitution products with higher stereoselectivity than the corresponding N-unsubstituted β-arylacrylamides. β-Arylacrylamides containing ortho-substituents led to the formation of only one stereoisomer. The procedure was used to prepare 4-aryl-2-quinolones from β-(o-bromophenyl)acrylamide through a sequential Heck reaction and copper-catalyzed cyclization process.

The functionalized NHC obtained from salt 2 is a good ligand for palladium in the Heck–Matsudareaction of arenediazonium salts and different alkenes. The reaction is performed with low catalyst loading (0.5–1 mol-% of Pd) and in the absence of a base for acrylates. The protocol is also useful for the preparation of cinnamide derivatives. Compound U-77863 has been prepared successfully in good isolated

Potent and selective ligands for the dopamine 3 (D3) receptor are disclosed. The D3 receptor ligands have a structural formula (I) wherein X is C=O or SO2, R1 is C1-6 alkyl, R2 is aryl, heteroaryl, aryl, -(CH2)1-3aryl, or -(CH2)1-3heteroaryl, and n is 0 or 1. Methods of using the D3 receptor ligands in the treatment of diseases and conditions wherein modulation of the D3 receptor provides a benefit also are disclosed.
Acutelunginjury (ALI) is an inflammation-mediated respiratory disease with a high mortality rate. Medications with anti-inflammatory small molecules have been demonstrated in phase I and II clinical trials to considerably reduce the ALI mortality. In this study, two series of lansiumamide analogues were designed, synthesized, and evaluated for anti-inflammatory activity for ALI treatment. We found
急性肺损伤(ALI)是一种炎症介导的呼吸道疾病,死亡率很高。I 期和 II 期临床试验已证明含有抗炎小分子的药物可显着降低 ALI 死亡率。在这项研究中,设计、合成了两个系列的兰硫酰胺类似物,并评估了其治疗 ALI 的抗炎活性。我们发现化合物8n通过抑制LPS诱导的Raw264.7细胞中促炎细胞因子白细胞介素6(IL-6)和白细胞介素1β(IL-1β)的表达并激活Nrf2/HO表现出最佳的抗炎活性。 -1途径。此外,我们在LPS诱导的ALI小鼠模型中发现,化合物8n显着减少炎症细胞向肺组织的浸润,从而达到保护肺组织和改善ALI的效果。此外,我们的小鼠模型研究表明,化合物8n具有良好的祛痰作用。这些结果一致支持兰硫酰胺类似物8n代表了一类新型抗炎药,有潜力作为先导化合物进一步开发为治疗 ALI 的治疗药物。
