  Ten benzoxazole clubbed 2-pyrrolidinones (11–20) as human monoacylglycerol lipase inhibitors were designed on the criteria fulfilling the structural requirements and on the basis of previously reported inhibitors. The designed, synthesized, and characterized compounds (11–20) were screened against monoacylglycerol lipase (MAGL) in order to find potential inhibitors. Compounds 19 (4-NO2 derivative) and 20 (4-SO2NH2 derivative), with an IC50 value of 8.4 and 7.6 nM, were found most active, respectively. Both of them showed micromolar potency (IC50 value above 50 µM) against a close analogue, fatty acid amide hydrolase (FAAH), therefore considered as selective inhibitors of MAGL. Molecular docking studies of compounds 19 and 20 revealed that carbonyl of 2-pyrrolidinone moiety sited at the oxyanion hole of catalytic site of the enzyme stabilized with three hydrogen bonds (~2 Å) with Ala51, Met123, and Ser122, the amino acid residues responsible for the catalytic function of the enzyme. Remarkably, the physiochemical and pharmacokinetic properties of compounds 19 and 20, computed by QikProp, were found to be in the qualifying range as per the proposed guideline for good orally bioactive CNS drugs. In formalin-induced nociception test, compound 20 reduced the pain response in acute and late stages in a dose-dependent manner. They significantly demonstrated the reduction in pain response, having better potency than the positive control gabapentin (GBP), at 30 mg/kg dose. Compounds 19 and 20 were submitted to NCI, USA, for anticancer activity screening. Compounds 19 (NSC: 778839) and 20 (NSC: 778842) were found to have good anticancer activity on SNB-75 cell line of CNS cancer, exhibiting 35.49 and 31.88% growth inhibition (% GI), respectively.

  设计了十种苯并噁唑与2-吡咯酮结合的人类单酰甘油酶抑制剂（11-20），根据先前报道的抑制剂的结构要求和基础设计。设计、合成和表征的化合物（11-20）针对单酰甘油酶（MAGL）进行筛选，以寻找潜在的抑制剂。化合物19（4-NO2衍生物）和20（4-SO2NH2衍生物）的IC50值分别为8.4和7.6 nM，是最活跃的。它们对于一个相似的分子，脂肪酸酰胺水解酶（FAAH），显示出微摩尔级别的活性（IC50值大于50µM），因此被认为是MAGL的选择性抑制剂。化合物19和20的分子对接研究表明，2-吡咯酮结构中的酰基位于酶的催化位点的氧酰离子孔中，与负责酶催化功能的氨基酸残基Ala51、Met123和Ser122形成三个氢键（约2埃）。值得注意的是，通过QikProp计算，化合物19和20的理化和药代性质符合良好口服生物活性中枢神经系统药物的建议指南。在甲醛诱导的疼痛实验中，化合物20以剂量依赖方式减少了急性和迟发性阶段的疼痛反应。它们显著地减少了疼痛反应，比阳性对照加巴喷丁（GBP）在30毫克/千克剂量下具有更好的效力。化合物19和20被提交给美国国家癌症研究所（NCI）进行抗癌活性筛选。化合物19（NSC：778839）和20（NSC：778842）在中枢神经系统癌症SNB-75细胞系上表现出良好的抗癌活性，分别显示出35.49%和31.88%的生长抑制率（%GI）。

  A series of 2-substituted benzimidazoles, benzoxazoles were synthesized by the condensation reactions of 1-aryl-4-carboxy-2-pyrrolidinones and aromatic ortho-diamines or ortho-aminophenol. Alkylation of benzimidazoles with iodoalkanes led to 1-aryl-4-(1-alkyl-1H-benzimidazol-2-yl)-2-pyrrolidin- ones or 1,3-dialkylbenzimidazolium iodides. N-Subs- tituted γ-amino acids were prepared by the hydrolysis

  The emergence of multidrug-resistant pathogens necessitates the search for new antibiotics acting on previously unexplored targets. Nicotinate mononucleotide adenylyltransferase of the NadD family, an essential enzyme of NAD biosynthesis in most bacteria, was selected as a target for structure-based inhibitor development. To this end, the inventors have identified small molecule compounds that inhibit bacterial target enzymes by interacting with a novel inhibitory binding site on the enzyme while having no effect on functionally equivalent human enzymes.

  多重耐药病原体的出现需要寻找作用于先前未被开发的靶标的新抗生素。Nicotinate单核苷酸腺苷转移酶（NadD家族），是大多数细菌NAD生物合成的必需酶，被选为基于结构的抑制剂开发的目标。为此，发明人已经鉴定出小分子化合物，通过与酶上的新型抑制性结合位点相互作用来抑制细菌靶标酶，而对功能相当的人类酶没有影响。
