  Derivatives of 6,8-bridged 5,6,7,8-tetrahydro-1,6-naphthyridines, designed as analogues of huperzine A, were synthesised and evaluated as inhibitors of acetylcholinesterase. In a first approach, C3-bridged naphthyridines were constructed by internal nucleophilic aromatic substitution of 2-chloro-3-(1-piperidinylmethyl)pyridine precursors containing a 3-CO2Me group on the 1-piperidinyl ring moiety.

  6,8-桥接 5,6,7,8-四氢-1,6-萘啶的衍生物，设计为石杉碱 A 的类似物，合成并评估为乙酰胆碱酯酶抑制剂。在第一种方法中，C3-桥接萘啶是通过内部亲核芳香取代 2-氯-3-(1-哌啶基甲基)吡啶前体在 1-哌啶基环部分上含有 3-CO2Me 基团来构建的。或者，应用 6,8-二烯丙基取代的四氢-1,6-萘啶的闭环复分解来构建不饱和 C4 桥。一些目标化合物显示出对乙酰胆碱酯酶的抑制，但低于石杉碱甲。抑制活性的相对顺序可以通过基于乙酰胆碱酯酶 - 石杉碱甲复合物的已知晶体结构的比较对接模拟研究来合理化。

  study is undertaken to design and synthesize novel anti-inflammatory compounds. For this, quinoline and anthranilic acid, two medicinally-privileged moieties, were linked by pharmacophore hybridization, and following their computational assessments, three hybrids 5a–c were synthesized in good over all yields. The in vitro and in vivo anti-inflammatory potential of these hybrids was determined by anti-denaturation

  尽管全球患病率很高，但类风湿性关节炎缺乏令人满意的治疗方法。因此，本研究旨在设计和合成新型抗炎化合物。为此，通过药效团杂交将喹啉和邻氨基苯甲酸这两个药用特殊部分连接起来，并根据其计算评估，合成了三种杂合体5a-c，其所有产率均良好。这些杂种的体外和体内抗炎潜力是通过抗变性和抗蛋白酶以及角叉菜胶诱导的爪水肿模型来确定的。这些杂种的计算研究揭示了它们的药物相似性、最佳的药代动力学和较低的毒性。此外，它们表现出对 TNF-α、FLAP 和 COX-II 的高结合亲和力（-9.4 至 -10.6 kcal mol -1 ）和合适的结合相互作用。三步合成路线产生了杂种5a-c ，最后一步的产率为 83-86%。在50 μg mL -1浓度下，化合物5b的抗蛋白酶和抗变性活性显着高于5a和5c 。此外， 5b显着减轻了接受角叉菜胶的大鼠右爪的水肿。这项研究的结果表明了新型杂交品种在治疗类风湿性关节炎等炎症性疾病方面的药用价值。

  A series of A-ring and E-ring analogues of the natural product luotonin A, a known topoisomerase I poison, was evaluated for growth inhibition in human carcinoma and leukemia cell lines. Rational design of structures was based on analogues of the related alkaloid camptothecin, which has been demonstrated to exert cytotoxic effects by the same mechanism of action. When compared to luotonin A, several compounds exhibited an improved topoisomerase I-dependent growth inhibition of a human leukemia cell line. (C) 2007 Elsevier Ltd. All rights reserved.
• Triazolothiadizepinylquinolines as potential MetAP-2 and NMT inhibitors: Microwave-assisted synthesis, pharmacological evaluation and molecular docking studies

  The enzymes MetAP-2 and NMT play a crucial role in the process of myristoylation of oncoproteins which is deregulated in many types of cancers. Execution of both these enzymes is considered as strategy for the intervention of various cancers and relative fungal infections, and hence the discovery of novel MetAP-2 and NMT inhibitors necessitate their high relevancy. In this investigation, we have synthesized a series of novel seven-membered triazolothiadiazepinyl quinolines 10(a-m) distinctively under microwave irradiation technique and identified as selective MetAP-2 and NMT inhibitors. Amongst the functionalized derivatives when evaluated for the in vitro antifungal assay, compounds 10b, 10c, 10e and 10f were considered promising due to notable inhibitory effects (MIC = 0.2 mg/mL) on Aspergillus fumigatus. Screening of the anticancer activity against NCI-60 Human tumor cell lines portrayed that conjugates 10b, 10c, 10e and 10f were found to be moderately effective against the Renal Cancer cell line UO-31. The data acquired from biological studies was further validated by molecular docking studies and p harmaco kinetic evaluation. (C) 2019 Elsevier B.V. All rights reserved.

  A new series of 2,5 and 1,5-regioisomers of the tetrazolyl group viz., 3-[(5-benzyl/benzylthio-2H-tetrazol-2- yl) methyl]-2-chloro-6-substituted quinoline 6h-q and 3-[(5-benzyl/benzylthio-1H-tetrazol-1-yl) methyl]-2-chloro-6-substituted quinolines 7h-q were synthesized. Docking studies of all these compounds with DNA as target using PDB: 1AU5 and 453D revealed that the compounds 6h and 6i act as covalent cross linker on the DNA helix of the former and intercalate the latter both with higher C score values. Another set of docking studies in the active pocket of dihydrofolate reductase and N-myristoyl transferase as targets to assess antifungal activity revealed that compounds 6k, 6l, 6p and 7q (with bromo and fluro substituents) showcases different binding modes and hydrogen bonding. Further, the compounds were screened for anticancer activity (primary cytotoxicity) against NCI-60 Human tumor cell line at a single high dose (10(-5) M) concentration assay. Among the tested compounds, 6h has shown 99.28% of GI against Melanoma (SK-MEL-5) and compound 6i has shown 97.56% of GI against Breast Cancer (T-47D). Further, in vitro antifungal assay against A. fumigatus and C. albicans for these compounds 6h-q and 7h-q revealed potential to moderate activities as compared to the standard.
