  作为潜在甾醇 14α-脱甲基酶 (CYP51) 抑制剂的新型 4H-吡喃并[3,2-c]吡啶类似物的设计、合成、生物活性评价和分子动力学模拟

  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.
