    The use of phenoxyacetyl group for the protection of the exocyclic amino function of purine bases and acetyl group for cytosine in oligonucleotide synthesis by the cyanoethylphosphoramidite approach is described. A side reaction - i.e. partial replacement of phenoxyacetyl group of protected guanines by acetyl group - was observed during the capping step. It can be avoided by the use of phenoxyacetic

    The amino functions of the common 2′-deoxyribo- and ribonucleosides were blocked by the (2-cyanoethoxy)carbonyl group on treatment with 2-cyanoethyl carbonochloridate (5) or 1-[(2-cyanoethoxy)carbonyl]-3-methyl-1H-imidazolium chloride (6) leading to 7, 18, 8, 19, 9, and 20. In 2′-deoxyguanosine, the amide group was additionally blocked at the O6 position by the 2-cyanoethyl (27) and 2-(4-nitrophenyl)ethyl

  • Membrane-Permeable Octanoyloxybenzyl-Masked cNMPs As Novel Tools for Non-Invasive Cell Assays

    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,我们采用了辛酰基(OB)基团。我们进一步展示了化学稳定性和酶促活化的解研究,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。
  • A Regioselective Synthesis of Alkyl 2-(Guanin-9-yl)acetates as PNA Building Blocks from 7-(4-Nitrobenzyl)guanine Derivatives

    Guanine derivatives substituted at N7 with 4-R-benzyl groups (R = H, MeO, NO2) have been evaluated in the regioselective N9-alkylation of guanine. Given the capricious removal of (substituted) benzyl groups from guanine derivatives and pent-4-enoylation of guaninium hydrochloride, an improved alternative approach has been elaborated consisting in the pent-4-enoylation and per-O-acetylation of guanosine (8), 4-nitrobenzylation at N7 followed by N-glycoside hydrolysis (10), N9-alkylation (13) and deprotection with sodium dithionite to afford the peptide nucleic acid building block tert-butyl [N2-(pent-4-enoyl)guanin-9-yl]- acetate (15) in 36% overall yield. This avoids N7 regioisomer formation, solubility problems and any chromatographic purification. A remarkable influence of the O- and/or N2-acyl groups on the stability of N-glycosidic bond and reactivity of 2-amino group was observed. The structure of a pyrimidine by-product 12 arising from the imidazole ring-opening of guaninium salt 4d in alkaline medium has been elucidated by 2D NMR.

    鸟嘌呤生物在N7位置被4-R-苄基基团(R = H,MeO,NO2)取代,已在鸟嘌呤的N9-烷基化中进行评估。鉴于从鸟嘌呤生物中(取代的)苄基基团的善变去除和鸟嘌呤盐酸盐的pent-4-酰化,已制定了一种改进的替代方法,包括pent-4-酰化和guanosine的per-O-乙酰化(8),N7位置的4-硝基苄基化,后接N-糖苷解(10),N9-烷基化(13)和用亚硫酸钠去保护以得到肽核酸构建块tert-丁基[N2-(pent-4-酰)鸟嘌呤-9-基]-乙酸(15),总收率为36%。这避免了N7位置异构体的形成,溶解度问题和任何色谱纯化。观察到O-和/或N2-酰基对N-糖苷键的稳定性和2-基基团的反应性具有显著影响。通过2D NMR阐明了在碱性介质中由鸟嘌呤盐4d的咪唑环开环产生的嘧啶副产物12的结构。

The surrogate of GDP-Fuc was synthesized as a 9:1 alpha/beta anomeric mixture, in 40% yield, starting from chlorosulfonyl isocyanate, perbenzylated l-fucopyranose, and a guanosine derivative, protected on the exocyclic amine and secondary
