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.

Synthesis and evaluation of novel N-3-benzimidazolephenylbisamide derivatives for antiproliferative and Hedgehog pathway inhibitory activity
de derivatives bearing the 4-benzyloxyphenyl moiety were synthesized and evaluated for their antiproliferativeactivity against MGC803, HT29, MKN45 and SW620 cancer cell lines in vitro. The pharmacological data demonstrated that the majority of the target compounds exhibited higher efficacy against MGC803, HT29 and MKN45 cells, among which compound 7m displayed higher antiproliferativeactivity than

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。
