  Quinazolineacetic acids and related analogs as aldose reductase inhibitors

  摘要：

  A variety of 2,4-dioxoquinazolineacetic acids (10, 11) were synthesized as hybrids of the known aldose reductase inhibitors alrestatin (8), ICI-105,552 (9), and ICI-128,436 (2) and evaluated for their ability to inhibit partially purified bovine lens aldose reductase (in vitro) and their effectiveness to decrease galactitol accumulation in the 4-day galactosemic rat model (in vivo). In support to SAR studies, related analogues pyrimidinediones (12), dihydroquinazolones (13), and indazolidinones (14, 15) were synthesized and tested in the in vitro and in vivo assays. All prepared compounds (10-15) have shown a high level of in vitro activity (IC50 approximately 10(-6) to 4 x 10(-8) M). However, only the 2,4-quinazolinedione analogues 10 and 11, with similar N-aralkyl substitution found in 2 and 9, have exhibited good oral potency. The remaining compounds were either inactive or had only a marginal in vivo activity. The structure-activity data support the presence of a secondary hydrophobic pocket in the vicinity of the primary lipophilic region of the enzyme.

• Structure−Activity Relationships of a Series of Substituted Benzamides:  Potent D₂/5-HT₂ Antagonists and 5-HT_1a Agonists as Neuroleptic Agents

  A series of substituted (4-(4-(1,2-benzisothiazol-3-yl)-1-piperazinyl)butyl)benzamide derivatives was prepared and evaluated as potential atypical antipsychotic agents. The target compounds were readily prepared from their benzoyl chloride, benzoic acid, or isatoic anhydride precursors, and they were evaluated in vitro for their ability to bind to dopamine D2, serotonin 5-HT2, and serotonin 5-HT1a

  制备了一系列取代的（4-（4-（1,2-苯并噻唑-3-基）-1-哌嗪基）丁基）苯甲酰胺衍生物，并将其评估为潜在的非典型抗精神病药。目标化合物可以很容易地从其苯甲酰氯，苯甲酸或等位酸酐的前体制备，并在体外评估它们与多巴胺D2、5-羟色胺5-HT2和5-羟色胺5-HT1a受体结合的能力。为了评估这些化合物的潜在抗精神病活性，我们研究了它们在小鼠中抑制阿扑吗啡诱导的爬升反应的能力。进一步评估了选定的化合物，以确定其潜在的副作用。本文讨论了单取代的和多取代的苯甲酰胺的结构-活性关系。尽管几种类似物在体外和体内具有潜在的非典型抗精神病药活性，但蒽环酰胺77（1192U90）的药理作用却十分出色。这项研究的结果是，选择1192U90（2-氨基-N-（4-（4-（1,2-苯并噻唑-3-基）-1-哌嗪基）丁基）苯甲酰胺盐酸盐进行进一步评估。目前正在I期临床试验中，作为一种潜在的非典型抗精神病药。

  Drug-resistant malarial strains have been continuously emerging recently, which posts a great challenge for the global health. Therefore, new antimalarial drugs with novel targeting mechanisms are urgently needed for fighting drug-resistant malaria. NADH-ubiquinone oxidoreductase of Plasmodium falciparum (PfNDH2) represents a viable target for antimalarial drug development. However, the absence of

  最近，耐药性疟疾菌株不断出现，这对全球健康构成了巨大挑战。因此，迫切需要具有新颖靶向机制的新抗疟药来对抗耐药性疟疾。恶性疟原虫的NADH-泛醌氧化还原酶（Pf NDH2）代表了抗疟疾药物开发的可行目标。但是，缺乏有关Pf NDH2的结构信息限制了合理的药物设计和进一步的开发。在这里，我们首次报道了Af-，NADH-和RYL-552（一种新的抑制剂）结合状态的Pf NDH2蛋白的高分辨率晶体结构。该Pf的NDH2抑制剂通过潜在的变构机制，对体外耐药菌和体内寄生虫感染的小鼠均表现出出色的效力。此外，发现该抑制剂可以与二氢青蒿素（DHA）协同地结合使用。这些发现不仅对于基于疟疾Pf NDH2蛋白的药物开发很重要，而且对其他含有NDH2的致病微生物（如结核分枝杆菌）也可能具有广泛的意义。
