  • Design, synthesis, and evaluation of novel 2-substituted-4-aryl-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,5]oxazocin-5-ones as NK1 antagonists

    guinea pigs (59.4% at 0.3 mg/kg iv and 62.8% at 3 mg/kg id). Furthermore, the effect of 3g on bladder function appeared to differ from that of tolterodine, another classical anti-pollakiuria agent, as determined by the distention-induced rhythmic bladder contraction assay using a urethane-anesthetized guinea pig model. Compound 3g is expected to be a promising agent for the treatment of urinary incontinence
    制备了一系列新颖的双环嘧啶衍生物,作为寻找旨在治疗尿失禁的NK1拮抗剂的一部分。其中3g,带有4-乙酰基哌嗪基和2-甲基苯基的嘧啶并[4,5-b] [1,5]恶唑啉衍生物,显示出有效的NK1拮抗剂活性,其K(B)值​​为为0.105 nM,显着增加了豚鼠的有效膀胱容量(0.3 mg / kg iv时为59.4%,id 3 mg / kg时为62.8%)。此外,使用尿烷麻醉的豚鼠模型,通过扩张诱导的节律性膀胱收缩试验确定了3g对膀胱功能的影响似乎与另一种经典的抗尿蛋白尿症托特罗定不同。化合物3g有望成为治疗尿失禁的有前途的药物。
  • Process Development and Large-Scale Synthesis of NK1 Antagonist

    DOI:10.1248/cpb.56.176
    日期:——
    A scaleable synthetic route is described to obtain 2-(4-acetylpiperadin-1-yl)-6-[3,5-bis(trifluoromethyl)phenylmethyl]-4-(2-methylphenyl)-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,5]oxazocin-5-one (1, KRP-103) as a neurokinin (NK)1 antagonist. The key step in the synthesis is the intramolecular cyclization of N-[3,5-bis(trifluoromethyl)phenylmethyl]-N-(3-hydroxypropyl)-4-chloro-6-(2-methylphenyl)-2-methylthiopyrimidine-5-carboxamide (15) which was obtained by amide formation between 4-(2-methylphenyl)-2-methylthio-6-oxo-1,6-dihydropyrimidine-5-carboxylic acid (8) and 3-[3,5-bis(trifluoromethyl)phenylmethylamino]-1-propanol (3). Treatment of 15 with 1,8-diazabicyclo[5,4,0]undec-7-ene provided 6-[3,5-bis(trifluoromethyl)phenylmethyl]-4-(2-methylphenyl)-2-methylthio-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,5]oxazocin-5-one (6). This intermediate (6) is transformed into the candidate compound (1) by two steps; oxidation, and substitution reaction of the resultant sulfone (7) with 1-acetylpiperazine. This synthetic method is free of chromatographic purification and is amenable to large scale synthesis.
    本文描述了一种可规模化合成的路线,以获得 2-(4-乙酰基哌啶-1-基)-6-[3,5-双(三氟甲基)苯基甲基]-4-(2-甲基苯基)-6,7,8,9-四氢-5H-嘧啶并[4,5-b][1,5]恶唑啉-5-酮(1,KRP-103),作为神经激肽(NK)1 拮抗剂。合成的关键步骤是 N-[3,5-双(三氟甲基)苯基甲基]-N-(3-羟基丙基)-4-氯-6-(2-甲基苯基)-2-甲硫基嘧啶-5-甲酰胺(15)的分子内环化、4-(2-甲基苯基)-2-甲硫基-6-氧代-1, 6-二氢嘧啶-5-甲酸 (8) 与 3-[3,5-双(三氟甲基)苯基甲基氨基]-1-丙醇 (3) 形成酰胺。用 1,8-二氮杂双环[5,4,0]十一-7-烯处理 15,可得到 6-[3,5-双(三氟甲基)苯基甲基]-4-(2-甲基苯基)-2-甲硫基-6,7,8,9-四氢-5H-嘧啶并[4,5-b][1,5]恶唑啉-5-酮(6)。该中间体(6)通过两个步骤转化为候选化合物(1):氧化,以及生成的砜类化合物(7)与 1-乙酰基哌嗪发生取代反应。这种合成方法无需色谱纯化,适合大规模合成。

    The structurally novel pyrimido[4,5-b][1,5]oxazocine derivative 3, a hybrid compound of pyrido[4,3-b]- and [2,3-b]-1,5-oxazocine (1 and 2, respectively), was designed and synthesized. We examined the atropisomeric property and the NK1 antagonist activity of 3. Compound 3 was found to possess both a feature of 1, free rotation about the biaryl bond, and a feature of 2, potent in vivo activity.
    结构新颖的嘧啶并[4,5-b] [1,5]恶唑啉衍生物3,是吡啶并[4,3-b]-和[2,3-b] -1,5-恶唑嗪的杂化化合物(1和2),被设计和合成。我们检查了3的阻转异构性质和NK1拮抗剂活性。发现化合物3既具有1的特征,围绕联芳基键自由旋转,又具有2的特征,有效的体内活性。
  • Analysis of crucial structural requirements of 2-substituted pyrimido[4,5-b][1,5]oxazocines as NK1 receptor antagonist by axially chiral derivatives
    作者:Shigeki Seto、Jun Asano

    日期:2007.8
    2-substituted 8-methylpyrimido[4,5-b][1,5]oxazocine derivatives. Axially chiral 8-methylpyrimido[4,5-b][1,5]oxazocines bearing a substituent at the C-2 position were synthesized and evaluated as NK(1) antagonists. The results revealed that (aR, 8S)-stereochemistry and the substituent at the C-2 position are important for NK(1) receptor recognition.
