of Alzheimer's disease (AD) through pharmacophores-merged approaches based on lead compounds 18d, benzyloxy phenyl analogs, and deferiprone (DFP). These hybrids possessed potent MonoamineoxidaseB (MAO-B) inhibition as well as excellent iron chelation, with pFe3+ values ranging from 18.13 to 19.39. Among all the compounds, 8g exhibited the most potent selective MAO-B inhibitor (IC50 = 68.4 nM, SI

The hedgehog (Hh) signaling pathway is involved in diverse aspects of cellular events. Aberrant activation of Hh signaling pathway drives oncogenic transformation for a wide range of cancers, and it is therefore a promising target in cancer therapy. In the principle of association and ring‐opening, we designed and synthesized a series of Hh signaling pathwayinhibitors with phenyl imidazole scaffold
刺猬 (Hh) 信号通路参与细胞事件的各个方面。Hh 信号通路的异常激活驱动了多种癌症的致癌转化,因此它是癌症治疗的一个有希望的目标。本着缔合和开环原理,我们设计合成了一系列具有苯基咪唑支架的Hh信号通路抑制剂,并在Gli-Luc报告基因检测中进行了生物学评估。化合物25被鉴定为具有纳摩尔 IC 50 的高效能,此外,它保留了对野生型和耐药性 Smo 过表达细胞的抑制作用。化合物25的分子模型研究 阐述了其与Smo受体的结合方式,为苯基咪唑类似物的进一步结构修饰提供了基础。

[Object] To provide a compound which can be used for the treatment of a disease associated with fatty acid amide hydrolase (FAAH), particularly urinary frequency, urinary incontinence and/or overactive bladder.
[Means for solution] It is confirmed that a urea compound chemical-structurally characterized by having a piperidine or piperazine ring or a salt thereof has an excellent FAAH-inhibitory activity, and thus the present invention is completed. The urea compound or its pharmaceutically acceptable salt of the present invention can increase the effective bladder capacity and ameliorate the state of urinary frequency, and is therefore useful as an agent for treating urinary frequency, urinary incontinence and/or overactive bladder.
explored the chemical space of FAM NR4A ligands by using fragment screening, in silico analysis, and systematic structure–activity relationship evaluation. From a chemically diverse library of 92 fragments, we identified 11 new FAM NR4A agonist and inverse agonist scaffolds. Structural optimization of the most active FAM fragment yielded NR4A agonists with submicromolar potency and binding affinity, demonstrating
