  摘要：

  α-重氮吡唑酰胺与硫化物的催化对映选择性[2,3] Stevens和Sommelet-Hauser重排是通过使用手性N，N'-二氧化物/镍（II）络合物催化剂实现的。这些重排反应在温和的反应条件下进行得很好，可以快速，轻松地获得一系列具有高到极好的对映选择性的官能化的1,6-二羰基或亚砜取代的苯乙酸酯。催化系统显示出出色的立体控制，可区分硫的异位孤对，并控制1,3-质子转移和[2,3]-σ重排。

  Discovery of 3-Methyl-N-(1-oxy-3‘,4‘,5‘,6‘-tetrahydro-2‘H-[2,4‘-bipyridine]-1‘-ylmethyl)benzamide (ABT-670), an Orally Bioavailable Dopamine D₄ Agonist for the Treatment of Erectile Dysfunction

  摘要：

  The goal of this study was to identify a structurally distinct D-4-selective agonist with superior oral bioavailability to our first-generation clinical candidate 1a (ABT-724) for the potential treatment of erectile dysfunction. Arylpiperazines such as (heteroarylmethyl) piperazine 1a, benzamide 2, and acetamides such as 3a,b exhibit poor oral bioavailability. Structure-activity relationship (SAR) studies with the arylpiperidine template provided potent partial agonists such as 4d and 5k that demonstrated no improvement in oral bioavailability. Further optimization with the (N-oxy-2-pyridinyl) piperidine template led to the discovery of compound 6b (ABT-670), which exhibited excellent oral bioavailability in rat, dog, and monkey (68%, 85%, and 91%, respectively) with comparable efficacy, safety, and tolerability to 1a. The N-oxy-2-pyridinyl moiety not only provided the structural motif required for agonist function but also reduced metabolism rates. The SAR study leading to the discovery of 6b is described herein.

  NS2B‐NS3 protease inhibitor with a 2‐6‐[2‐(5‐phenyl‐4H‐[1,2,4]triazol‐3‐ylsulfanyl)acetylamino]benzothiazol‐2‐ylsulfanyl}acetamide scaffold was identified during screening. Optimization of this initial hit by synthesis and screening of a focused compound library with this scaffold led to the identification of a novel uncompetitive inhibitor (1 a24, IC50=3.4±0.2 μM) of the WNV NS2B‐NS3 protease.

  近年来，由西尼罗河病毒（WNV）感染引起的临床症状严重程度恶化，老年人神经侵袭性疾病的发生频率增加。由于目前尚无成功的抗WNV疗法用于人类，因此迫切需要为开发新的针对该病毒的化学疗法而不断努力。由于其在病毒复制中的重要性及其独特的底物偏爱性，病毒NS2B-NS3蛋白酶是有希望的病毒抑制靶标。在这项研究中，WNV NS2B-NS3蛋白酶抑制剂具有2- 6- [2-（5-苯基-4H]在筛选过程中发现了[[1,2,4]三唑-3-基硫烷基]乙酰氨基]苯并噻唑-2-基硫基}乙酰胺支架。通过合成和的筛选该初始命中的优化聚焦化合物库与此支架导致的新颖非竞争性抑制剂的鉴定（1 A24，IC 50 = 3.4±0.2μ中号的WNV的NS2B-NS3蛋白酶）。1 a24分子对接至WNV蛋白酶表明该化合物干扰NS2B辅因子与NS3蛋白酶的生产性相互作用，并且是WNV NS3蛋白酶的变构抑制剂。
