    Nitrogen's reactivity of various 3-alkoxypyrazoles
    摘要:
    Our current interest in the design of original chemical libraries featuring a pyrazole nucleus led us to focus on the chemistry of the 3-alkoxy-5-methylpyrazoles we have recently made readily available. With in mind the preparation of an array of the less accessible 1-arylpyrazol-3-ones, the present report describes the respective nitrogen's reactivity of various 3-alkoxypyrazoles toward arylation reaction, using arylboronic acids, as well as alkylation reactions using methyl iodide or benzylbromide. The structure assignments of the isomers obtained were achieved using long distance N-15-H-1 NMR correlation measurements or by the recourse to unambiguous synthetic pathways. (c) 2009 Elsevier Ltd.

    摘要:
    为了有效合成杂环化合物,已经开发了一种实验技术,即超声静态加热。该技术涉及超声辐射和静态加热过程。首先,在温和条件下执行超声辐照过程以形成杂环化合物的中间体,随后的静态加热过程(在无溶剂条件下加热中间体而无需搅拌)通过分子内消除反应生成目标杂环化合物。

    Abstract

    Chemoselective O‐alkylation of 1‐aryl‐3‐polyfluoroalkylpyrazol‐5‐oles under basic conditions resulted in a series of 5‐alkoxypyrazoles (26 derivatives). They showed an acceptable ADME profile (in silico) and can be considered as drug‐like. In experiments in vivo (CD‐1 mice), it was found that the obtained compounds do not have toxic properties at a dose of more than 150 mg/kg (for most compounds at a dose of >300 mg/kg, and for lead compounds – >600 mg/kg). 22 Compounds from this series demonstrated from moderate to high analgesic effects (28–104 % at 1 h and 37–109 % at 2 h after administration) in vivo in the hot plate test (SD rats, 15 mg/kg, intraperitoneal (ip)). The lead compound was 4‐([1‐phenyl‐3‐(trifluoromethyl)pyrazol‐5‐yl]oxy)butan‐1‐ol, which not only increased the latent period in the hot plate test by 103 % at both measurement points but also showed a pronounced analgesic effect under conditions of capsaicin‐induced nociception (CD‐1 mice, 15 mg/kg, ip). According to molecular modeling, all synthesized compounds can interact with the TRPV1 ion channel. This biological target was confirmed in in vitro experiments on Chinese hamster ovary cells expressing rTRPV1. 5‐Alkoxypyrazoles were partial agonists of the TRPV1 ion channel in various degree, and the most active was the same pyrazole as in in vivo tests.

    摘要在碱性条件下对 1-芳基-3-聚氟烷基吡唑-5-醇进行化学选择性 O-烷基化反应,产生了一系列 5-烷氧基吡唑(26 种衍生物)。这些衍生物显示出可接受的 ADME 特征(在学中),可被视为类药物。在体内(CD-1 小鼠)实验中发现,获得的化合物在剂量超过 150 毫克/千克时不会产生毒性(大多数化合物的剂量为 300 毫克/千克,主要化合物的剂量为 600 毫克/千克)。22 在热板试验(SD 大鼠,15 毫克/千克,腹腔注射 (ip))中,该系列化合物显示出中等到较高的镇痛效果(给药后 1 小时为 28-104%,2 小时为 37-109%)。领头化合物是 4-([1-苯基-3-(三氟甲基)吡唑-5-基]氧基)丁-1-醇,它不仅使热板试验的潜伏期在两个测量点都延长了 103%,而且在辣椒素诱导的痛觉条件下(CD-1 小鼠,15 毫克/千克,ip)显示出明显的镇痛效果。根据分子模型,所有合成化合物都能与 TRPV1 离子通道相互作用。在表达 rTRPV1 的中国仓鼠卵巢细胞上进行的体外实验证实了这一生物靶点。5-烷氧基吡唑在不同程度上是 TRPV1 离子通道的部分激动剂,其中活性最强的是与体内试验相同的吡唑
