  Development of fluorinated CB2 receptor agonists for PET studies

  摘要：

  A convergent strategy was followed to modify systematically carbazole based CB2 receptor ligands. The length of the N-(fluoroalkyl) group (n in 7), the length of the alkanamide (m in 7) and the substitution pattern of the phenyl moiety (X and Y in 7) were varied systematically. The highest CB2 affinity was found for the 2-fluoroethyl substituted carbazole derivative 20a (K-i = 5.8 nM) containing the propionamide and the 2-bromo-4-fluorophenyl moiety. According to docking studies 20a fits nicely into the binding pocket of the CB2 receptor, but elongation of the fluoroethyl side chain leads to a different binding mode of the ligands. The high CB2 affinity together with the high selectivity over the CB2 subtype qualifies the fluoroethyl derivative 20a to be developed as a PET tracer. (C) 2013 Elsevier Ltd. All rights reserved.

  第二代 1,2,4-恶二唑衍生物，具有增强的溶解度，可抑制埃及伊蚊的 3-羟基犬尿氨酸转氨酶 (HKT)

  摘要：

  控制埃及伊蚊种群最广泛使用的方法是化学控制方法。它代表了一种通过病媒控制来遏制多种疾病（例如登革热、寨卡、基孔肯雅热、黄热病）的省时且经济有效的方法。因此，为了最大限度地减少杀虫剂抗药性的上升，必须发现与现有化合物具有不同作用方式的新化合物。解毒酶是发现新杀虫剂的一个有吸引力的目标。犬尿氨酸途径是一条重要的代谢途径，它产生化学稳定的黄尿酸，由活性氧和氮物质的前体 3-羟基犬尿氨酸通过 3-羟基犬尿氨酸转氨酶 (HKT) 生物合成。此前，我们通过体外和计算机研究报道了 1,2,4-恶二唑衍生物作为埃及伊蚊和 AeHKT 抑制剂的杀幼剂的有效性。在这里，我们报道了新型 4-[3-(芳基)-1,2,4-恶二唑-5-基]丙酸钠的合成及其同源 HKT 抑制活性。这些新衍生物可作为竞争性抑制剂，IC 50值在 42 至 339 μM 范围内。我们进一步对我们小组先前报道的先前合成的4-[3-(芳基)-1

  The synthesis of 3-(3-aryl-1,2,4-oxadiazol-5-yl)propionic acids from arylamidoximes and succinic anhydride under focused microwave irradiation conditions is described. The new synthetic method furnished the desired products in 2-3 min and good yields. Furthermore, the previously complicated purification procedure has been simplified in a manner which is quick, eco-friendly and cost-effective. Larvicidal

  描述了在聚焦微波辐射条件下由芳基嘧啶和琥珀酸酐合成3-（3-芳基-1,2,4-恶二唑-5-基）丙酸。新的合成方法可在2-3分钟内提供所需的产品，并具有良好的产量。此外，先前复杂的纯化过程已经以快速，环保和成本有效的方式得到简化。使用几种3-（3-芳基-1,2,4-恶二唑-5-基）丙酸进行了杀幼虫的生物测定和真菌生长抑制试验。这些酸对埃及伊蚊的L4幼虫具有很强的杀幼虫活性。结果表明，杀幼虫活性可能与除氟原子以外的苯环对位的吸电子取代基的存在有关。在幼虫生物测定中，1,2,4-恶二唑在虹吸管和肛门乳头的幼虫螺旋瓣中观察到的变化是幼虫死亡的原因。此外，在初步评估中，所有酸均抑制了五种不同类型的真菌（即镰刀镰刀菌，尖孢镰刀菌，念珠形镰刀菌，十二指肠球菌和红曲霉）的真菌生长。这两个活性都首次公开了在丙酸的C-3处连接的1,2,4-恶二唑-5-基环。

  CB2受体是止痛药和抗炎药的有吸引力的治疗靶标。在本文中，我们描述了发现一类新的恶二唑衍生物的发现，由此开发了有效的和选择性的CB2激动剂。通过使用药效团模型结合一系列物理化学过滤器对样品集合进行虚拟筛选，从大麻靶偏倚的文库中识别出最初的第7个匹配项。7被证明是选择性CB2激动剂（CB2 EC50 = 93 nM，Emax = 98％，CB1 EC50> 10 microM）。但是，该化合物在大鼠中表现出较差的溶解性和相对较高的清除率，导致口服生物利用度低。在本文中，我们报告了有关提高功效，理化性质和溶解度的7条途径的详细SAR研究。
