  摘要：

  为了发现潜在的甾醇 14α-去甲基酶 (CYP51) 抑制剂，设计并合成了 34 种未报道的 4 H-吡喃并[3,2- c ]吡啶衍生物。测定结果表明，大多数化合物在 16 μg/mL 浓度下对核盘菌、胶状炭疽菌、灰葡萄孢、指状青霉和尖孢镰刀菌表现出显着的杀菌活性。化合物7a 、 7b和7f对抗灰霉病的半数最大有效浓度(EC 50 )值分别为0.326、0.530和0.610。即，它们比氧环唑具有更好的抗真菌活性（EC 50 = 0.670 μg/mL）。同时，它们对CYP51的半数抑制浓度（IC 50 ）值分别为0.377、0.611和0.748 μg/mL，这表明它们也比氧环唑（IC 50 = 0.802 μg/mL）具有更好的抑制活性。蛋白质的荧光猝灭测试表明7a和7b具有与氧环唑相似的猝灭模式。分子动力学模拟表明7a和氧环唑与CYP51的结合自由能分别为-35.4和-27.6 kcal/mol。

  A new series of 3,5-bis(arylidene)-4-piperidones, as chalcone analogues carrying variety of aryl and heteroaryl groups, pyrazolo[4,3-c]pyridines, pyrido[4,3-d]pyrimidines, and pyrido[3,2-c]-pyridines, carrying an arylidene moiety, and a series of pyrano[3,2-c]pyridines, as flavone and coumarin isosteres, were synthesized and screened for their in vitro antiviral and antitumor activities at the National Cancer Institute (NCI). Compounds 9 and 18 proved to be active against herpes simplex virus-1 (HSV-1), while compound 13 showed moderate activity against human immunodeficiency virus-1 (HIV-1). Compounds 14, 26, 28, 33, and 35 exhibited a broad spectrum antitumor activity. In addition, compounds 26, 33, and 35 proved to be of moderate selectivity toward leukemia cell lines. The pyrano[3,2-c]pyridines heterocyclic system proved to be the most active antitumors among the investigated heterocycles.

  An atom efficient, green protocol for the synthesis of fifteen 2-amino-6-methyl-4-aryl-8-[(E)-arylmethylidene]-5,6,7,8-tetrahydro4H-pyrano[3,2-c] pyridine-3-carbonitriles in quantitative yields from the reaction of 1-methyl-3,5-bis[(E)-arylmethylidene]tetrahydro-4(1H)-pyridinones with malononitrile in presence of solid sodium ethoxide under solvent-free condition is described. The compounds were tested for their in vitro activity against Mycobacterium tuberculosis H37Rv (MTB), multi-drug resistant tuberculosis (MDR-TB), and Mycobacterium smegmatis using agar dilution method. 2-Amino-4-[4-(dimethylamino) phenyl]-8-(E)-[4(dimethylamino) phenyl] methylidene-6-methyl-5,6,7,8-tetrahydro-4H-pyrano[3,2-c]-pyridine-3-carbonitrile was found to be the most potent compound (MIC: 0.43 mu M) against MTB and MDR-TB, being 100 times more active than standard, isoniazid against MDRTB.

  To discover potential sterol 14α-demethylase (CYP51) inhibitors, thirty-four unreported 4H-pyrano[3,2-c]pyridine derivatives were designed and synthesized. The assay results indicated that most compounds displayed significant fungicidal activity against Sclerotinia sclerotiorum, Colletotrichum lagenarium, Botrytis cinerea, Penicillium digitatum, and Fusarium oxysporum at 16 μg/mL.
