  摘要：

  为了能够研究细胞内的第二信使 d-肌醇-1,4,5-三磷酸腺苷（InsP3）及其受体（InsP3Rs），人们希望开发出受保护的 InsP3 衍生物，这种衍生物能够在细胞外应用时进入细胞。随后，细胞内的酶会去除亲脂性保护基团，释放出 InsP3，从而激活 InsP3R。报告了两种 d-肌醇 1,4,5-三磷酸己二异（丁酰氧基甲基）酯（d-InsP3/BM）和一种 l-InsP3/BM的合成。研究表明，细胞外施用 d-对映体会导致 Ca2+ 释放，这被认为是通过 InsP3Rs 发生的。应用 l-对映体则几乎没有 Ca2+ 释放。

  Cyclic ADP-ribose (cADPR) is a second messenger that acts on ryanodine receptors to mobilize Ca2+. cADPR has a net negative charge at physiological pH making it not passively membrane permeant thereby requiring it to be injected, electroporated or loaded via liposomes. Such membrane impermeance of other charged intracellular messengers (including cyclic AMP, inositol 1,4,5-trisphosphate and nicotinic acid adenine dinucleotide phosphate) and fluorescent dyes (including fura-2 and fluorescein) has been overcome by synthesizing masked analogs (prodrugs), which are passively permeant and hydrolyzed to the parent compound inside cells. We now report the synthesis and biological activity of acetoxymethyl (AM) and butoxymethyl (BM) analogs of cADPR. Extracellular addition of cADPR-AM or cADPR-BM to neuronal cells in primary culture or PC12 neuroblastoma cells induced increases in cytosolic Ca2+. Pre-incubation of PC12 cells with thapsigargin, ryanodine or caffeine eliminated the response to cADPR-AM, whereas the response still occurred in the absence of extracellular Ca2+. Combined, these data demonstrate that masked cADPR analogs are cell-permeant and biologically active. We hope these cell-permeant tools will facilitate cADPR research and reveal its diverse physiological functions. (C) 2012 Elsevier Inc. All rights reserved.

  Phytic acid (IP6) is an ingredient in cereals and legumes, and limited amounts of this compound are considered to enter the cell and exert anti-cancer effects. These effects have been seen by studying cells treated with around 1-5 mM IP6. However, such a large amount of IP6 chelates metals and changes the pH in cell culture medium. To overcome this problem, we synthesized a prodrug of IP6 (Pro-IP6) and elucidated generation of IP6 from Pro-IP6 in cells. Cellular experiments using Pro-IP6 demonstrated selective anti-cancer effects including apoptosis and inhibition of Akt activation. Furthermore, an in vivo study using mice with adult T-cell leukemia also showed that Pro-IP6 reduced the size of the cancer. Taken together, Pro-IP6 is a useful biological tool and may lead to development of new anti-cancer drugs.
