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。
Revisiting a Receptor-Based Pharmacophore Hypothesis for Human A<sub>2A</sub> Adenosine Receptor Antagonists
The application of both structure- and ligand-based design approaches represents to date one of the most useful strategies in the discovery of new drug candidates. In the present paper, we investigated how the application of docking-driven conformational analysis can improve the predictive ability of 3D-QSAR statistical models. With the use of the crystallographic structure in complex with the high affinity antagonist ZM 241385 (4-(2-[7-amino-2-(2-furyl)[1,2,4]-triazolo [2,3-a][1,3,5]triazin-5-ylamino]ethyl)phenol), we revisited a general pharmacophore hypothesis for the human A(2A) adenosine receptor of a set of 751 known antagonists, by applying an integrated ligand- and structure-based approach. Our novel pharmacophore hypothesis has been validated by using an external test set of 29 newly synthesized human adenosine receptor antagonists.
