  Photocleavable Protecting Groups as Nucleobase Protections Allowed the Solid-Phase Synthesis of Base-Sensitive SATE-Prooligonucleotides

  摘要：

  The first synthesis of oligodeoxynucleotide heteropolymers carrying base-sensitive S-pivaloylthioethyl (t-Bu-SATE) phosphotriester linkages has been performed. It is based on the use of 6-nitroveratryloxycarbonyl (NVOC) and 2,2'-bis(2-nitrophenyl)ethoxycarbonyl (diNPEOC) groups as nucleobase protections in combination with photolysis deprotection. The synthesis was realized using the phosphoramidite approach on solid support bearing a 1-(o-nitrophenyl)-1,3-propanediol linker. The removal of the protecting groups and the cleavage of the oligonucleotides from the solid support were accomplished in a single photolysis procedure upon UV irradiation at wavelengths >300 nn. Faster deprotection rates were observed for diNPEOC-protected nucleosides and oligomers than with NVOC-protected ones. The synthesis of pentanucleoside t-Bu-SATE-phosphotriesters d((5')TpCpCpCpTp(3')), d((5')TpApApApAp(3')), and d((5')TpGpGpGpTp(3')) and of dodecanucleoside t-Bu-SATE-phosphotriesters and -phosphorothioate d((5')ApCpApCpCpCpApApTpTpCpTp(3')) and d((5')ApGpApApTpTpGpGpGpTpGpTp(3')) demonstrated the efficiency of the method.

  Adenine nucleotide (AN) 2nd messengers, such as 3′,5′-cyclic adenosine monophosphate (cAMP), are central elements of intracellular signaling, but many details of their underlying processes remain elusive. Like all nucleotides, cyclic nucleotide monophosphates (cNMPs) are net-negatively charged at physiologic pH which limits their applicability in cell-based settings. Thus, many cellular assays rely on sophisticated techniques like microinjection or electroporation. This setup is not feasible for medium- to high-throughput formats, and the mechanic stress that cells are exposed to raises the probability of interfering artefacts or false-positives. Here, we present a short and flexible chemical route yielding membrane-permeable, bio-reversibly masked cNMPs for which we employed the octanoyloxybenzyl (OB) group. We further show hydrolysis studies on chemical stability and enzymatic activation, and present results of real-time assays, where we used cAMP and Ca2+ live cell imaging to demonstrate high permeability and prompt intracellular conversion of some selected masked cNMPs. Based on these results, our novel OB-masked cNMPs constitute valuable precursor-tools for non-invasive studies on intracellular signaling.

  腺嘌呤核苷酸（AN）第二信使，如3′,5′-环腺苷单磷酸（cAMP），是细胞内信号传导的中心元素，但其潜在过程的许多细节仍然不明确。像所有核苷酸一样，环核苷酸单磷酸（cNMPs）在生理pH下是净负电荷，这限制了它们在基于细胞的设置中的适用性。因此，许多细胞分析依赖于微注射或电穿孔等复杂技术。这种设置对于中高通量格式来说是不可行的，而细胞所受的机械应力增加了干扰性伪迹或假阳性的可能性。在这里，我们提出了一种简短灵活的化学途径，产生了可渗透膜、可生物逆转掩蔽的cNMPs，我们采用了辛酰氧基苯基（OB）基团。我们进一步展示了化学稳定性和酶促活化的水解研究，并呈现了实时分析结果，我们使用cAMP和Ca2+活细胞成像来展示一些选定掩蔽cNMPs的高渗透性和迅速的细胞内转化。基于这些结果，我们的新型OB掩蔽cNMPs构成了用于细胞内信号研究的有价值的前体工具。
