Design, synthesis and in vitro evaluation of amidoximes as histone deacetylase inhibitors for cancer therapy
摘要:
Amindoximes are geometric isomers of N-hydroxyamidines which are bioisosteres of hydroxamates. Since amindoxime group is capable of chelating transition metal ions including zinc ion, amindoximes should possess histone deacetylases (HDACs) inhibitory activity. In this work, we designed and synthesized a series of amindoximes, examined their inhibitory activities against HDACs, and investigated their cytotoxicity to human cancer cells. Preliminary results demonstrated that amindoximes possessed submicromolar HDACs inhibitory activity, with noteworthy enhancement compared with hydroxamates. Furthermore, the amindoximes arrested HCT116 and A549 cells in G2/M phase and showed good efficacy in inducing cells death. We provided a proof-of-concept that amindoximes could be used as HDACs inhibitors and hold great promise as epigenetic drugs. (C) 2016 Elsevier Ltd. All rights reserved.

Six structural motifs based on the initial (lead) structure of merbarone were designed, prepared, and tested against the glioblastoma LN-229 cell line. Three different structural moieties were modified in the search for optimal glioblastoma activity: the 1,3-diazinane moiety, the aryl moiety, and the heteroatom linker. Calculated molecular descriptors such as lipophilicity (ClogP), acidic strength (calculated pK(a)), and polar surface area (PSA) were used to design a diverse structural library of these compounds. From six different structural motifs and 136 compounds, a handful of examples with moderate (100 mu g/ml), good (10 mu g/ml) and excellent (1 mu g/ml) glioblastoma activity were elucidated.

1,3-Disubstituted benzazepines as neuropeptide Y Y1 receptor antagonists
A nuclei, have been designed, synthesized, and evaluated for activity. Through a blind screening we found the compound 1-N-(3-(N'-(tert-butoxycarbonyl)amino)benzyl)-7-methoxy-(3-(3)-methylureido)-2,3,4,5-tetrahydro-1H-1-benzazepin-2-one (9: IC50 = 1.6 mu M). Chemical modifications of 9 gave a potent NPY Y1 antagonist 3-(N-(4-hydroxyphenyl)-N'-methylguanidino)-1-N-(3-(N'-(tert-butoxycarbonyl)amino)benzyl)-2,3,4,5-tetrahydro-1H-1-benzazepin-2-one (14c: IC50 = 43 nM), which had no affinity for NPY Y2 and Y5 receptors.
