  New Serotonin 5-HT_1A Receptor Agonists Endowed with Antinociceptive Activity in Vivo

  摘要：

  We report the synthesis of new compounds 4-35 based on two different openings (A and B) of the chromane ring present in the previously identified 5-HT1A receptor (5-HT1AR) ligand 3. The synthesized compounds were assessed for binding affinity, selectivity, and functional activity at the 5-HT1AR Selected candidates resulting from B opening were also evaluated for their potential antinociceptive effect in vivo and pharmacokinetic properties in vitro. Analogue 19 [2-(4-{[2-(2-ethoxyphenoxy)ethyl]amino}butyl)tetrahydro-1H-pyrrolo[1,2-c]imidazole-1,3(2H)-dione] has been characterized as a high-affinity and potent 5-HT1AR agonist (K-i = 2.3 nM; EC50 = 19 nM). Pharmacokinetic studies indicated that compound 19 displays a good metabolic stability in human liver microsomes (t(1/2) similar to 3 h and CLint = 3.5 mL/min/kg, at 5 mu M), and a low level of protein binding (25%, at 5 mu M). Interestingly, 19 (3 mg/kg, ip, and 30 mg/kg, po) caused significant attenuation of formalin-induced behavior in early and late phases of the mouse intradermal formalin test of pain, and this in vivo effect was reversed by the selective 5-HT1AR antagonist WAY-100635. Thus, the new 5-HT1AR agonist identified in this work, 19, exhibits oral analgesic activity, and the results herein represent a step toward identifying new therapeutics for the control of pain.

  A concise method to directly generate benzyl radicals from benzyl alcohol derivatives has been developed. The simple and inexpensive combination of TiCl4(collidine) (collidine = 2,4,6-collidine) and manganese powder afforded a low-valent titanium reagent, which facilitated homolytic cleavage of benzylic C–OH bonds. The application to radical conjugate addition reactions demonstrated the broad scope

  Come full circle: A method for the nucleophilic amination of methoxy arenes was established by using sodium hydride (NaH) in the presence of lithium iodide (LiI). This method offers an efficient route to benzannulated nitrogen heterocycles. Mechanistic studies showed that the reaction proceeds through an unusual concerted nucleophilic aromatic substitution.

  reoperation was 85.4% at 5 years. Multiple factors still influence early and late survival after surgery for type A aortic dissection. Preoperative renal impairment both affects early and late outcome. Early postoperative course affects late outcome in hospital survivors. The presence of the intimal tear in the aortic arch has a negative impact on late survival.

  这项研究的目的是确定在15年内进行A型主动脉夹层手术的患者中与早期和晚期死亡率相关的最重要变量。从1984年1月到1999年3月，有110例患者接受了A型主动脉夹层的手术。88.1％的患者患有急性A型清扫术（AD），11.8％的患者患有慢性清扫术（CD）。心脏压塞和休克分别发生在21.8％和14.5％的患者中。原发性内膜撕裂的位置在升主动脉中占70.9％，在弓中占17.2％，在降主动脉中占7.2％。进行单因素和多因素分析以鉴定与院内死亡独立相关的非栓塞变量。Kaplan-Meier和Cox回归分析以及死亡风险的危害函数用于分析影响整体生存和手术生存的因素。总体住院死亡率为20.9％（23/110例患者），CD占9％，AD占21.6％。紧急手术的住院死亡率为47.6％，而非紧急手术的住院死亡率为13.7％（p <0.01）。单因素分析显示41例术前和手术变量，包括年龄（岁），年龄> 70岁，
• 7-Amino-2-phenylpyrazolo[4,3-d]pyrimidine derivatives: Structural investigations at the 5-position to target human A1 and A2A adenosine receptors. Molecular modeling and pharmacological studies

  In previous research, several 7-amino-2-arylpyrazolo[4,3-d]pyrimidine derivatives were identified as highly potent and selective antagonists at the human A3 adenosine receptor. Structure-activity relationship studies highlighted that affinity and selectivity depended on the nature of the substituents at the 5- and 7-positions of the pyrazolo[4,3-d]pyrimidine scaffold. In particular, small lipophilic residues at the 5-position and a free amino group at position 7 afforded compounds able to bind all four human (h) adenosine receptors. Hence, to shift affinity toward the hA1 and/or hA(2A) subtypes, alkyl and arylalkyl chains of different length were appended at position 5 of the 2-phenylpyrazolo[4,3-d]pyrimidin-7-amine. Among the new compounds, a dual hA1/hA(2A) receptor antagonist was identified, namely the 5-(3-phenylpropyl) derivative 25, which shows high affinity both at human A1 (K(i) = 5.31 nM) and A(2A) (K(i) = 55 nM) receptors. We also obtained some potent and selective antagonists for the A1 receptor, such as the 5-(3-arylpropyl)-substituted compounds 26-31, whose affinities fall in the low nanomolar range (K(i) = 0.15-18 nM). Through an in silico receptor-driven approach, the obtained binding data were rationalized and the molecular bases of the hA1 and hA(2A) AR affinity and selectivity of derivatives 25-31 are explained.
