Novel androgen receptor full antagonists: Design, synthesis, and a docking study of glycerol and aminoglycerol derivatives that contain p-carborane cages
androgen receptor (AR), glycerol and aminoglycerol derivatives were designed and synthesized as a novel type of carborane-containing AR modulators. The (R)-isomer of 6c, whose chirality is derivedfrom the glycerol group, showed 20 times more potent cell inhibitory activity against LNCaP cell lines expressing T877A-mutated AR than the corresponding (S)-isomer. Docking studies of both isomers with AR

cell growth inhibitory activity against four human cancer cell lines (MCF-7, MDA-MB-453, LNCaP, and PC-3). The biological evaluation of a series of derivatives of 2a revealed that an increased number of methoxy groups on the benzene ring of 2a enhanced the cell growth inhibitory activity. Trimethoxyphenyl derivative 2g afforded the most potent cell growth inhibitory activity (mean GI50 value: 5.8 μM)
1,2-Dicarba-closo-dodecaboranes (o-carboranes) and naphthalenes have potential value as components or building blocks for supramolecular systems, We have efficiently synthesized 1-(1,2-dicarba-closo-dodecaboran-1-yl) naphthalene and 2-(1,2-dicarba-closo-dodecaboran-1-yl) naphthalene derivatives by employing three preparative methods: cyclization of the corresponding acetylenes with decaborane(14), an Ullmann-type coupling reaction of carboranes with aryl halide, and the aromatic nucleophilic substitution (SNAr) reaction of aryl-o-carboranes with nitrophenyl halide, The optimum conditions of each method for synthesis of the title compounds were also investigated.

The female hormone 17 beta-estradiol (E2) is synthesized from estrone by steroid sulfatase (STS), and metabolized into 2-methoxyestradiol (2-ME), whereby the biological activity of the latter is substantially different from that of E2. Based on the metabolic pathways of E2, a carborane-containing 2-ME mimic (1c) and its derivatives (1 and 2) were designed and synthesized as novel multitarget anticancer agents. Bissulfamate 1f exhibited potent STS-inhibitory activity and tubulin-polymerization-inhibitory activity. Moreover, the cell-growth-inhibitory (CGI) activity of 1f was similar to that of 2-ME in a panel screening against 39 human cancer cell lines. Accordingly, 1f should be a promising perspective therapeutic agent for hormone-dependent breast tissue. (C) 2017 Elsevier Ltd. All rights reserved.
