  Characterization of a Novel Analogue of 1α,25(OH)₂-Vitamin D₃ with Two Side Chains:  Interaction with Its Nuclear Receptor and Cellular Actions

  摘要：

  The hormone 1 alpha,25(OH)(2)-vitamin D-3 (125D) binds to its nuclear receptor (VDR) to stimulate gene transcription activity. Inversion of configuration at C-20 of the side chain to generate 20-epi-1 alpha,25(OH)(2)Da (20E-125D) increases transcription 200-5000-fold over 125D with its 20-normal (20N) side chain. This enhancement has been attributed to the VDR ligand-binding domain (LBD) having different contact sites for 20N and 20E side chains that generate different VDR conformations. We synthesized 1 alpha,25-dihydroxy-21-(3-hydroxy-3-methylbutyl) vitamin D-3 (Gemini) with two six-carbon side chains (both 20N and 20E orientations). Energy minimization calculations indicate the Gemini side chain possesses significantly more energy minima than either 125D or 20E-125D (2346, 207, and 127 minima, respectively). We compared activities of 125D, 20E-125D, and Gemini, respectively,in several assays: binding to wild-type (100%, 147%, and 38%)and C-terminal-truncated mutant VDR; transcriptional activity (of the transfected osteopontin promoter in ROS 17/2.8 cells: ED50 10, 0.005, and 1.0 nM) mediation of conformational changes in VDR assessed by protease clipping major trypsin-resistant fragment of 34, 34, and 28 kDa). For inhibition of cellular clonal growth of human leukemia (HL-60) and breast cancer (MCF7) cell lines, the ED50(125D)/ED50(Gem) was respectively 380 and 316. We conclude that while Gemini readily binds to the VDR and generates unique conformational changes, none of them is able to permit a superior gene transcription activity despite the presence of a 20E side chain.

• High specific activity tritium labeling of vitamin D derivative RO275646

  The octahydroindenone intermediate was tritium labeled using T2O isotope exchange labeling, and then elaborated to the vitamin D derivative RO275646. Though this method of labeling was expected to give the minor isomer, it was the shortest and most convenient route to the high specific activity metabolically stable labeled sites. A total of 34 mCi (from two separate runs) at 64 Ci/mmol of [3H]-RO275646

  八氢茚酮中间体使用 T2O 同位素交换标记进行氚标记，然后精制为维生素 D 衍生物 RO275646。尽管预计这种标记方法会产生次要异构体，但它是获得高比活性代谢稳定标记位点的最短和最方便的途径。通过该方法制备了总共 34 mCi（来自两次单独的运行），浓度为 64 Ci/mmol 的 [3H]-RO275646。版权所有 © 2005 John Wiley & Sons, Ltd.
