Synthesis of C-14 labeled GABAAα2/α3 selective partial agonists and the investigation of late-occurring and long-circulating metabolites of GABAAreceptor modulator AZD7325
cycloaddition of pyridinium ylides with alkynes was investigated under mild conditions. A series of 13 pyridinium salts was prepared by alkylation of 4-substituted pyridines. Their reactivity with propiolic ester or amide in various reaction conditions (different temperatures, solvents, added bases) was studied, and 11 indolizines, with three points of structural variation, were, thus, isolated and

The invention relates to 3-((hetero-)aryl)-8-amino-2-oxo-1,3-diaza-spiro-[4.5]-decane derivatives, their preparation and their use in medicine, particularly in the treatment of pain.
Fluorine is a highly attractive element for both medicinal chemistry and imaging technologies. To facilitate proteintyrosinephosphatase (PTP)-targeted drug discovery and imaging-guided PTP research on fluorine, several highly potent and 19F MR sensitive PTP inhibitors were discovered through a structure-based focused library strategy.

We uncovered that mPTPB subverts the innate immune responses by blocking the ERK1/2 and p38 mediated IL-6 production and promoting host cell survival by activating the Akt pathway. We identified a potent and selectivemPTPBinhibitor I-A09 with highly efficacious cellular activity, from a combinatorial library of bidentate benzofuran salicylic acid derivatives assembled by click chemistry. We demonstrated
violaceoruber, has excellent anti-inflammatory potential. Herein, a biogenetically modeled approach to synthesize violacin A and twenty-five analogues was described, which involved the preparation of aromatic polyketide precursor through Claisen condensation and its spontaneous cyclization. The inhibitory effect on nitric oxide (NO) production of all synthetic molecules was evaluated by lipopolysaccharide
Violacin A 是一种色满酮衍生物,从Streptomyces violaceoruber的发酵液中分离出来,具有出色的抗炎潜力。在此,描述了一种合成紫罗兰 A 和 25 种类似物的生物遗传学建模方法,该方法涉及通过克莱森缩合及其自发环化制备芳香聚酮化合物前体。通过脂多糖 (LPS) 诱导的 Raw264.7 细胞评估对所有合成分子的一氧化氮 (NO) 产生的抑制作用。结果表明,在C-7上引入脂肪胺基团明显提高了violacin A的抗炎作用,并且侧链上的芳香醚代替酮基有利于提高活性。其中,模拟7a和16d被筛选为最有效的抗炎候选药物。分子机制研究表明,7a和16d由于抑制NF-κB信号通路而获得抗炎能力。
