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)
based on p-carborane (an icosahedral carbon-containing boron cluster) as a hydrophobic core structure. Here, we report the design, synthesis and biological evaluation of carborane-based vitamin D analogs bearing various substituents at the diol moiety. Among the synthesized compounds, methylene derivative 31 exhibited the most potent vitamin D activity, which was comparable to that of the natural hormone
非类固醇维生素D受体(VDR)配体是许多临床应用中有希望的候选物。最近,我们开发了一种基于新的非secosteroidal VDR激动剂p -carborane(二十面体含碳硼簇)作为疏水性核心结构。在这里,我们报告在二醇部分带有各种取代基的基于硼烷的维生素D类似物的设计,合成和生物学评估。在合成的化合物中,亚甲基衍生物31具有最强的维生素D活性,与天然激素1α,25(OH)2 D 3相当。。该化合物是迄今为止报道的最有效的非类固醇类VDR激动剂之一,是开发新型候选药物的有希望的先导。
Synthesis and structure–activity relationship of p-carborane-based non-secosteroidal vitamin D analogs
different from classical secosteroidal vitamin D analogs. Here, we report systematic synthesis and activity evaluation of carborane-based non-secosteroidal vitamin D analogs. The structure–activity relationships of carborane derivatives are different from those of secosteroidal vitamin D derivatives, and in particular, the length and the substituent position of the dihydroxylated side chain are rather
1α,25-二羟基维生素D 3 [1α,25(OH)2 D 3:1 ]是核维生素D受体(VDR)的特定调节剂,新型维生素D类似物是多种临床应用的治疗候选物。我们最近开发了带有p的非类固醇VDR激动剂-碳硼烷笼(含碳的硼簇)作为疏水核结构。这些碳硼烷衍生物在结构上与经典的类固醇维生素D类似物完全不同。在这里,我们报告基于碳硼烷的非secosteroidal维生素D类似物的系统合成和活性评估。碳硼烷衍生物的结构-活性关系与类固醇维生素D衍生物的结构-活性关系不同,特别是,二羟基化侧链的长度和取代基位置在碳硼烷衍生物中相当灵活。此处介绍的结构-活性关系应有助于开发用于临床应用的非类固醇维生素D类似物。
